"Time's up, Momonga onii-chan!"
-Bukubukuchagama using her voice acting.

Bukubukuchagama (ぶくぶく茶釜) is one of the three female guild members of Ainz Ooal Gown and regarded as one of the Forty-One Supreme Beings by the NPCs of the Great Tomb of Nazarick. She is the older sister of Peroroncino and the creator of Aura Bella Fiora and Mare Bello Fiore.


Bukubukuchagama’s exact race and appearance is unknown. Since Peroroncino described her as an "Odd-looking pink flesh," it seems her appearance is quite grotesque.


Bukubukuchagama had a cheerful nature and enjoyed playing pranks on her friends. She can be at times mischievous around her little brother's friend Momonga. When she acts serious, she would often quarrel with Peroroncino, insisting on the notion that the younger brother must obey their older sister. In that regard, Bukubukuchagama's thoughts influenced the relationship between Aura and Mare, a pair of siblings similar to the kind she shared with her brother.

Moreover, Bukubukuchagama usually speaks in the high pitch tone she uses for acting. Whenever Bukubukuchagama had to reprimand her brother, she would become a very scary person, as described by the other guild members. Because of that, her tone would suddenly change, and she would use her original deeper voice to scold him. She tends to be mindful of the words spoken by her brother strictly so. For that reason, she would even scold Peroroncino for saying something she doesn't like to hear from him.


Bukubukuchagama Emblem

Bukubukuchagama's Emblem

Bukubukuchagama is one of the three female members of Ainz Ooal Gown. Due to her race, Bukubukuchagama had trouble joining with a party before she met Momonga and Touch Me. After meeting the World Champion, she joins his clan which is Nine's Own Goal prior to the formation of Ainz Ooal Gown guild. The story behind that problem was when Bukubukuchagama was not able to find a party of her own to adventure. She couldn't easily adventure with other players due to her appearance, but with the exception of Touch Me who was the first to volunteer allowed her to join him. 

In real life, she is a famous voice actress, who often played young girl characters in H-Games to earn money. Bukubukuchagama's younger brother, Peroroncino, who played YGGDRASIL with her, happened to stumble upon one of the H-Games she had played a role in. After discovering that Bukubukuchagama was a voice actor for one of the heroines in the game he wanted to buy and play, her brother lost further interest in it since then.

Bukubukuchagama's mainstream stage name happens to be called Kazeumi Kumi. Her old fans used to refer her as Kaze-chin.[1]

Only in the Web Novel, from a distant past, Bukubukuchagama had once visited the Gigantic Tree within the 6th Floor of Nazarick where her NPCs created by her reside in. When Bukubukuchagama was around, there were several guests who visited there alongside her. They were the female members of Ainz Ooal Gown such as Yamaiko and Ankoro Mocchi Mochi. Along with the subordinates her friends have created. While Bukubukuchagama was staying in the Gigantic Tree, Aura would often be seated on her Bukubukuchagama’s lap.

For instance, Aura's dresser was filled with extravagant dresses and feminine clothes selected and then collected by Bukubukuchagama for her NPC to try out wearing. There were remnants of the time where Bukubukuchagama used Aura as a dress-up doll alongside the variety of plushies she has given to her to complement the elf's look.[2]

Bukubukuchagama has was a fierce proponent of the Field of Flowers as it was a safe spot to do her photo shooting. Due to this Tabula Smaragdina helped create Photo Studio Tabula of her personal use.[3] And also the Beauty Parlor to satisfy her desire to recreate a scene of a particular old movie.[4]

During a raid against a boss, her brother Peroroncino's cover fire had accidentally killed it, robbing Ulbert Alain Odle and Touch Me of the glory. Bukubukuchagama berated her sibling for the mistake, demanding he kneel and apologize, though her teammates were fine with the result.[5]


The Undead King Arc

Prior to YGGDRASIL's silent shut-down at the end of the game, Momonga recalls all the good times he had with the members of Ainz Ooal Gown, including Bukubukuchagama. In his lamentation of his fellow guild-mates departure a few minutes before him, the Great Tomb of Nazarick and all of its NPCs were transported to the New World.[6]

Later, when he meets the Floor Guardians in the 6th Floor, Momonga is surprised by how similar Shalltear’s and Aura’s relationship is to their creators, Peroroncino and Bukubukuchagama.[7]

The Bloody Valkyrie Arc

Main article: The Bloody Valkyrie Arc

Sebas asked Shalltear about her relationship with Aura and why they seem to be on bad terms with each other. Shalltear simply replies that this is the way Peroroncino created her and wonders if Bukubukuchagama made Aura's setting to be at odds with her. She also informs Sebas that Peroroncino and Bukubukuchagama are siblings, so in a way, she and Aura are also considered sisters.

The group discusses about Bukubukuchagama's job as a voice actor and the powers they assumed she possesses. Because Shalltear has no knowledge about the real world, she assumes that Bukubukuchagama's job as a voice actress has the power to create life.[8]

Ainz equips Bukubukuchagama's Wristwatch before attacking Shalltear with his super-tier spell. During the battle, the voice from his friend's watch began to show its effect, signaling to him the exact time where the battle between them can be finished.[9]

When Aura is working in the construction site in the Great Forest of Tob, Bukubukuchagama's wristwatch given to her by Ainz announces its break time. Despite having no need to rest, eat or sleep because she wears a Ring of Sustenance, she decides to do so because her own master worried about the well being of everyone.[10]

The Ruler of Conspiracy Arc

Main article: The Ruler of Conspiracy Arc

Aura and Mare suggested a rule where boys should dress like girls, and girls should dress like boys. Ainz is surprised by this suggestion and screamed Bukubukuchagama's name internally. He rejects the idea of thinking it would be like declaring to all parties inside and outside the country that the Sorcerer Kingdom was a nation that valued cross-dressing. Ainz is able to fool Aura and Mare by saying that they are special beings created by Bukubukuchagama and that only they should be dressed the way they are.

In Ainz's mind, he felt Bukubukuchagama would be interested in the idea of having all men and women within a nation cross-dress. However, he shortly thereafter started to doubt that would be the case for her. This was upon taking into consideration if Bukubukuchagama was in the New World with him, Ainz believes she would definitely not want to make a country like that.

On the other hand, he also thought what sort of reaction Bukubukuchagama would act around her NPCs if she learned about them developing their own egos. He described that Bukubukuchagama will probably avoid meeting her creation, Aura and Mare.[14]

The Craftsman of Dwarf Arc

Main article: The Craftsman of Dwarf Arc

When Ainz told Aura that he was planning to enlist the help of Shalltear during his journey to the Dwarf Kingdom, it left the dark elf shocked, considering that she has very limited uses. Seeing how Aura acted the way she did towards Shalltear, it reminded Ainz of the sibling relationship shared between Bukubukuchagama and her younger brother. He remembers Bukubukuchagama's concern whether Peroroncino had been causing problems for her companions to which the latter replied no, making her feel baffled by it that he had not done anything wrong yet. Along the way, he inquires Aura about how she would respond to his orders if it conflicted with her creator Bukubukuchagama's orders, leaving the dark elf uncertain on what to do. Nonetheless, Aura prayed to Bukubukuchagama in hopes of Shalltear being able to successfully complete her mission without problem as she is created by her brother. Meanwhile, Ainz made note of all the rewards he had given out to the NPCs so far for their hard work. One of them was Bukubukuchagama's Wristwatch awarded to her creation Aura.[15][16]

Shalltear's Travel Diary Arc

Main article: Shalltear's Travel Diary Arc

The next morning after a night spent in the fortress conjured by Ainz, while heading to the Dwarf Kingdom, Aura and Shalltear greet Ainz. Ainz seeing their chipper attitudes asks how their night was. The two mistakenly think that Ainz knows about their musings from last night and apologize, begging for punishment. Though Ainz is confused, states that there is nothing wrong, as he believes they were just chatting about their creators, Bukubukuchagama and Peroroncino, and thus did not press the issue any further.[17]

The Paladin of the Holy Kingdom Arc

The Witch of the Falling Kingdom Arc

Main article: The Witch of the Falling Kingdom

When Mare feels hesitant in being able to successfully fulfill his task, he felt that his creator Bukubukuchagama would be angry to see him acting distraught like this. Mare couldn't help but tearfully imagine Bukubukuchagama disciplining him. Seeing how poor his results are after destroying a town during the beginning of the Sorcerer Kingdom's war with the Re-Estize Kingdom, Mare felt deeply disappointed at himself for bringing shame upon Bukubukuchagama. However, his master Ainz's words of encouragement spurred Mare back to his senses, giving the elf the resolve to not give up on himself. Mare was more than ever determined to destroy more towns and cities and kill more people to become the person Bukubukuchagama wanted him to be.[19]

The Half Elf God-kin Arc

Main article: The Half Elf God-kin I and The Half Elf God-kin II Arc

Upon hearing that Ainz wanted to have a nice place to hold a conversation with the Elven Slaves, Aura suggested that they could do it outdoors on the 6th Floor. She offered him the use of a table and parasols that Bukubukuchagama used when conversing with the other Supreme Beings and had left behind in the Gigantic Tree.[20]

During Ainz’s vacation in the Elf Country, he gave Mare Elemental Gacha to supplement the dark elf’s summoning abilities with another summoning item that given to Mare by Bukubukuchagama.[21]

For Mission: Red Ogre Cried, Aura crafted cover story for her and Mare that their parent was currently missing and that they were being cared for by the uncle. After she earned the trust of the dark elves, Ainz and Mare prepared to head to the Dark Elf Village. Though before doing so Ainz asked Mare to forgo wearing his normal attire. Mare agreed to the request, reasoning Bukubukuchagama would understand. Later Ainz who was observing Aura interact with the dark elves mused that she had Bukubukuchagama’s personality.[22]

Abilities and Powers

Bukubukuchagama is specialized in defensive ability. She had the title of "The Unsinkable." She is very skilled as a player and played the role of a commander. Her swift and accurate judgments, born of long experience with the game, placed her firmly in the top class of YGGDRASIL's players. She was skilled at hate management, which was a difficult task since hate was a hidden value, especially in a data-heavy game like YGGDRASIL.

Since the guild is working together, she had to put the whole team together as a tank. While her character’s stats are low, she is able to compensate that sort of weakness with first-class defensive items. Whenever the whole guild is away, she would hold down the fort for them until they returned. Additionally, she was immune to the negative status effects that undead could inflict her with, like poison or paralysis.[23]

Though her race suffered a racial penalty for wearing items like armor or shield, the slime still did things like equipping shields in both hands or using special skills to harden her clay-like body.

As her younger brother's close friend, she got along quite well with Momonga. She gave him a wristwatch with her voice as the alarm. The reason why a mainstream voice actress like herself would affect such a vexing tone was clearly because she wanted to tease Ainz. Momonga trust her skills as a player and followed her instructions. In a sense, he admired her for how she was skilled at hate management, which was a difficult task since hate was a hidden value. They worked in the same team to clear the Great Tomb of Nazarick. 


Bukubukuchagama often had a quarrel with him, mainly because she thinks of Peroroncino, as her younger brother, who must act obediently towards her. Her creations, Aura and Mare, reflects her ideal relationship between siblings. Peroroncino had to genuflect before her because she has blackmail material on him from when he was twelve years old.


She had a friendly relationship with Yamaiko. She used to call her Yama-chan in the past. Yamaiko said that there is no need for her to sound like a cute child because her normal voice was already pleasant enough, which Bukubukuchagama jokingly replied that she fell in love with her. They worked in the same team to clear the Great Tomb of Nazarick. Yamaiko trusted her skills as a gamer and would follow her instructions.

Ulbert Alain Odle

They worked in the same team to clear the Great Tomb of Nazarick. Ulbert trusted her skills as a player and would follow her instructions.

Warrior Takemikazuchi

They worked in the same team to clear the Great Tomb of Nazarick. Nishikienrai trusted her skills as a player and would follow her instructions.


Flatfoot thinks that Bukubukuchagama is scary, being scarier than his department chief.

Aura Bella Fiora & Mare Bello Fiore

As Bukubukuchagama is the creator of both Aura and Mare, the twins revere and respect's Bukubukuchagama the most out of the Forty-One Supreme Beings of Ainz Ooal Gown and withholds their loyalty first and foremost to her alone.

Bukubukuchagama is Aura's creator. Her dominance over Mare is most likely due to her belief that younger brothers should listen to their older sisters. Aura is shown to greatly love Bukubukuchagama and misses her dearly, as seen where she greatly delights in the wristwatch given to her by Ainz and smiles and blushes heavily whenever she hears her creators voice. Her love for Bukubukuchagama was so great that she even holds more affection for the Wristwatch over her own pets and longingly desires to hear more of her creator's voice.

Bukubukuchagama is Mare's creator. She programmed him to be a pushover whom is constantly ordered around by Aura. This is because of her belief that the younger brothers should listen to their older sisters. She also dressed him like a girl for some unknown reason.

Mare like his sister, its shown to greatly love and long for his creator despite the unusual tendencies given to him by Bukubukuchagama, its shown that Mare actually takes immense pride in his cross dressing and upon learning from Ainz that this tendency was made exclusively for him and him alone by his creator, Mare immediately bursted into happiness and declared that he would allow no one but his sister to share in the uniqueness made for him by Bukubukuchagama.

Ankoro Mocchi Mochi

The two of them get along very well and were really close as companions, a trait that their NPCs inherited.

Variable Talisman

While friends, Bukubukuchagama admitted to the tanker, that she couldn't look his avatar in the eye, due to his centipede face being too much for her to handle.[24]

  • Bubble Bubble (ぶくぶく) is also used as a word to depict a fat person. In fact, she was fat in the past, but she succeeded in losing weight when she played YGGDRASIL.
  • Bukubukuchagama is very similar in name to Bunpuku Chagama, a japanese folklore about a shape-shifting tanuki.
  • Shalltear knows that her job is a voice actress, but due to her lack of knowledge about the World of 2138, she misunderstood voice actress as a class that creates life.
  • According to Peroroncino, Bukubukuchagama had a less mainstream stage name, Kazeumi Kumi. Her old fans used to call her Kaze-chin. Bukubukuchagama changed it several times, but she liked it the best.
  • Suzuki Satoru had a photo of Bukubukuchagama dressed as a princess in a white dress while holding a shield aloft. According to him, it depicts herself happily riding a pumpkin carriage which she, as a girl, has always dreamed of doing.[25]
  • Despite not knowing much mythological or cultural concepts, Bukubukuchagama is familiar with Cthulhu Mythos as she her work was involved in the media.
  • During her YGGDRASIL exploring career, when Nishikienrai found a geyser that gushed water at regular intervals, Warrior Takemikazuchi and Bukubukuchagama believed it to be a common game gimmick and that the geyser could propel a player in the air to a hidden scaffold. However it turn out just to be only hot water, causing Nishikienrai to suffer damage to his game avatar.[26]


  • (Bukubukuchagama's Childish Voice): "Momonga-oniichan! I’m setting the time!"
  • (To her companions concerning Peroroncino): "Has my stupid little brother given you any trouble?"
  • (To Peroroncino): "...People might laugh it off at a drinking party, but do you really think you can shout this sort of thing out just because you're among friends?"
  • (To Peroroncino): "Oi, brat. Do you want me to tell everyone about what you did when you were twelve?"
  • (To Peroroncino): "...Hey, did I give you permission to shut up? Did that sound like a joke to you? Hah? You'd better—"
  • (To Peroroncino): "Oi, dumbass brother of mine. Remember this well — mind your manners, even if you get along with people. Especially when you crack your dirty jokes. Don't embarrass me just because you get excited around friends. Got it?"
  • (To Yamaiko): "Let's not talk about marriage, Yama-chan. You see, I am everyone's idol Chagama-san, so all talk of lovers and weddings are forbidden."
  • (To Yamaiko): "You shouldn't say that, Yama-chan~ people discover new things because of folks like Ulbert-san who want to find them. Sometimes they might even find a loophole, but that's expected of those shitty devs."
  • (To Momonga): "Momonga-san, don't be mistaken. This isn't taking on a hardship, but rather, it's because we're like this that we can take it on at all. Look, in terms of physical damage dealing, defense, magical damage dealing, healing and support, we're probably the most specialized members of Nine's — no, of Ainz Ooal Gown. If I could put a team together to fight that boss, I'd probably pick all of us again."
  • (To both the Death Knight and Asura): "You're the best, Death Knight-kun! Now look at me, you son of a bitch!"
