Tsuibayaya (どごその馬鹿 (ツイバヤヤ) ) is a dwarf craftsman from Mass for the Dead.


He is a dwarf with rust-colored hair and beard with a rosy nose. Tsuibayaya has muscular arms and wears a blue tunic underneath a green coverall with suspenders and thick green gloves. On his brow are a pair of lens goggles.


Tsuibayaya though hailed by his human neighbors as a grumpy yet reliable craftsman, it is just a ruse that he created for the sake of his work. He was the kind of dwarf craftsman who has a personal hobby in making swimsuits to the point of obsession.

Tsuibayaya is quite the manipulative and selfish person as he expressly state’s that the fortunes of his adopted village or even the Kingdom matter to him not. All his deeds that he had done such as making tools for free and high-quality armor were merely to buy him social capital to gain the trust of the humans in the village to continue his swimwear research.


Some years ago, Tsuibayaya had become enthralled by the concept of the swimsuit from oral histories of his people. This was from during the time of when the Boastful Sage lived two hundred years ago. Unable to handle having just an imperfect concept of the object of his obsession, he left his hometown and chose to live in a seaside village in the Re-Estize Kingdom where there were legends of a mermaid. However to fund his work, Tsuibayaya may have stolen some ores and materials for his own purposes.

Though the villagers at the time were hesitant to accept an outsider, he eventually won them over, using all manners of tricks such as making tools for free and even teaching the men how to properly fight. While outwardly it appeared that he was a generous and vital member of the community, the dwarf only cared about setting up a shop to continue his research into water repellent materials for swimwear. After using various materials to craft his swimwear such as fish scales, animal fat, and livers, he came to the realization that the scales from the village's local legend, the "Legendary Mermaid" were a vital piece to his work. By studying an ancient poem that detailed on how to meet the mermaid, the dwarf realized that the time to meet would coincide when four stars shone specifically in the sky. In addition, the meeting place was located somewhere on the seaside, which was accessed through a cave that was unfortunately locked and gated by the village chief. Knowing full well he would need the key to get to the beach, in order to win over the chief, he started sharing alcohol from his homeland with the man.

At some point, Tsuibayaya's research required much needed funding. Thus to support his work, the craftsman entered into a private contract with the royal family of the Kingdom and began crafting high-quality armors several times a year.


Mass for the Dead Arc[]

Main article: Mass for the Dead Arc

Tsuibayaya in search for water repellent materials for his swimsuits believed that he needed the scales of the "Legendary Mermaid" to complete them. After many years of winning over the villagers in a seaside village, Tsuibayaya managed to make a copy of a key to the locked cave that led to the shore. He urgently needed to meet the mermaid soon as the time for a meeting would soon pass. His desire to complete his work, made him neglect his previous obligation to ready the armors for the Kingdom. Hence when he received a notice informing of the deadline, he chose to ignore it and went on to go do his quest.

To avoid suspicion from his neighbors, Tsuibayaya told the village that he would be away to attend a meeting. After leaving, the dwarf headed to the forbidden cave and used his key to open it. Traveling through the cave tunnel, he made his way to the isolated beach. Making camp at the shore, Tsuibayaya was attacked by Giant Crustaceans, but he managed to escape and head towards the cave network where he was pursued. Tsuibayaya was eventually found by the Nazarick contact party led by the protagonist and the adventurers of Blue Roses.

Despite being healed by Lakyus Alvein Dale Aindra and rescued from monsters, the dwarf refused to turn back to the village to give the adventurers the promised armors as he was busy. The dwarf was blackmailed by Lakyus, who threatened to inform the village that he was trespassing on an off limits area by the village. The dwarf then revealed his reasons to the group, and insisted in putting his own obsession before the Kingdom, stating all his efforts were for this moment to get the best materials for his swimsuits. After showing them his swimsuits, the dwarf would not back down to return to the village until he is able to meet with the Legendary Mermaid.

However, he did offer the adventurers a deal, in that he would give the armors to them if they helped him find the mermaid to get his materials. While the adventurers found his offer reprehensible, Lakyus accepted it to get the armors, inviting the protagonist and his friends along on the adventure. Once they agreed to get the armors for him, Tsuibayaya told them about the Legend of the Mermaid which possessed instructions of where and how to summon the Legendary Mermaid. Knowing that the beach happen to contain various types of aquatic monsters, the dwarf offered to lend his prototype swimwear equipment for Blue Roses to use minus Gagaran. While the adventurers accepted the items, his offer to help fit them into his gear properly was turned down by Lakyus who had Evileye use [Fly] to take him back to the village for his safety. Though the dwarf complained about being roughly handled by the ride back home, he did gift Evileye one of his other prototypes for her to use when she returned to her friends.

Upon receiving the scales from the Legendary Mermaid from the adventurers, the craftsman was elated at the find and rushed to work in his studio. Ignoring the impatience growing on Blue Roses, the dwarf revealed his perfect swimsuit to the women and selected Gagaran to wear it as he believed her to be the best to wear a form of ultimate beauty. Once the brawny adventurer wore it, the dwarf was moved by the sight of his masterpiece being finally completed at long last. In gratitude for realizing his dream, he allowed Gagaran to keep the swimsuit as a gift from him to her.

Once Blue Roses left with the armors that Tsuibayaya promised to the royal family he stood outside his village watching them go alongside the protagonist and his companions. Now that Tsuibayaya fully achieved his goal, the dwarf was at a loss of what to do with his life from now on. Tsuibayaya was beginning to have an existential crisis. The protagonist took pity on the passionate craftsmen, and decided to give him something to see. At once, the Pleiades present themselves in full swimwear regalia of the very items the dwarf had been trying to replicate. Seeing the actual item of his dreams and recognizing that they were far superior to his own masterpiece, reignited the dwarf's passion to craft an even better swimwear.

Eventually under Momonga's approval, the dwarf was allowed to keep some of Nazarick's swimwear for study in order to research them to produce superior varieties. Since then, the dwarf has been collaborating with Nazarick, producing new prototype swimwear for the NPCs to try on.[1]

Some time before the protagonist migrated to E-Rantel permanently, Tsuibayaya had already used the ones from Nazarick to reproduce several variations. Nazarick in the process of sending the Pleiades out to assist Cocytus in subjugating the other races in the Great Lake decided to test some of the prototypes out to see if they were well enough to consider mass production for use by their summons. Demiurge also wished to test the dwarves swimsuits to advance the idol project. The new swimsuits were tested out in Spa Resort Nazarick, though the dwarf's creations were durable the Pleiades still favored the swimsuits from the Treasury as they were more comfortable.[2]

After hearing the report from Lupusregina Beta and CZ2128 Delta who had infiltrated Six Arms the existence of "rune weapons" became known to Nazarick. Momonga who was unfamiliar with such weapons wondered if he should inquire Tsuibayaya on the matter.[3]

Tsuibayaya was reported to have moved to E-Rantel. He would be involved in Nazarick's promotion of a series of dolls based on Blue Roses for the Adventurer's Guild. The first doll the dwarf made in the series and released was Gagaran due to his impression of his first meeting with her.[4]

Tsuibayaya still living in E-Rantel, was part of the logistic force of the city, as well as the occasional weapon making, but still practiced his hobby of making swimsuits. During E-Rantel's Harvest Festival, organized by the protagonist into a version of Halloween, Tsuibayaya took an immediate interest in the swimsuit Slimeko was wearing for the masquerade. Upon examining it, he proclaimed it was a relic of the Boastful Sage and thought it was wasteful on Surako, thinking Gagaran was best suited for the item. The revelation, surprised the people in the crowd, as they did not realized the Sorcerer Kingdom had ties to such a illustrious hero of the past. Truth be told the dwarf's encounter with Slimeko was not by chance, but planned by the protagonist so that the craftsman would come to the conclusion of the relic and spread world of the Sorcerer Kingdom's alleged association with the Boastful Sage.[5]

The head of the logistics of E-Rantel was later summoned to a secret meeting by the protagonist and his partner Surako. This item asking for his help in constructing several items that were supposedly devised by the Boastful Sage. The dwarf was convinced this story after the homunculus gave him a copy of an ancient manuscript that was recently discovered in the Sorcerer Kingdom with details various inventions such as the Heating Box, Cooling Device, Scented Moisture Fan, Warm Pot, and a Loudspeaker. Tsuibayaya though was curious as to why the kingdom did not have its own craftsmen create these items, but bought the story that the protagonist's countrymen were more interested in weapons-development than daily household items. He understood the secrecy as it could be seen as a major embarrassment to the Sorcerer Kingdom if word of this got out, and agreed to keep quiet of his collaboration. In exchange Tsuibayaya was given Momonga's personal swimsuit surfer brief to study which the dwarf was excited to have and admire on his wall, given they were a a new variant and was promised a new swimsuit when he finished his task. Tsuibayaya completed all the items in two days, save for the Warm Pot as it was similar to the Heating Box, and they were delivered to the protagonist in items for the "Sorcerer Kingdom Daily Household Magic Item Fair".[6]

Tsuibayaya aid was later requested by the protagonist to gain a swimsuit for Saint Clementine for her to use in an operation to eliminate a Super Giant Sanitary Slime created by Zurrernorn for a Death Spiral ritual. The craftsman was happy enough to provide the Holy Maiden his latest work, and even wanted to come along for the duration of the operation taking place in the sewers, but was told not to by the protagonist as it was too dangerous.

After the end of the operation and the public announcement by the adventurers and the saint in E-Rantel's city square, Tsuibayaya came rushing over to Clementine to ask about the performance of his swimsuit. Later after seeing all the publicity of how his work helped the city, the dwarf hoped that it would shine interest on swimsuits with the rest of the world. Tsuibayaya was last seen having Clementine at his workshop, busying himself examining her and the equipment to find ways to improve it.[7]

Just before leading an expedition to the Dwarf Kingdom, the protagonist had originally wanted to bring Tsuibayaya on as a guide, however the dwarf declined as he explained the circumstances of his departure from his homeland and may be regarded as a thief that would not be welcomed back. By chance the expedition encountered a dwarf named Bigosa in the abandoned dwarven city of Feo Raidho who just so happened to be Tsuibayaya's father.[8]

Months after the "Calamity of Cracks", Tsuibayaya participated in the Festival of E-Rantel's Reconstruction. He was seen among the vendors in the city's streets showcasing the items from the Sorcerer Kingdom, which included his prized swimsuit.[9]

After the success of Nazarick's Bard Plan leading to the creation of the rock band Βγδth, the next phase of the plan was to subtly introduce the musical instruments used by the band members to E-Rantel. Since many of the instruments like the electric guitar and stand mic did not exist in the New World, Momonga had the protagonist, Slimeko and Narberal recruit Tsuibayaya to create a contemporary prototype of the items. The dwarf complied and managed to reverse engineer the electric guitar as well as the stand mic, after being told that they were items uncovered to be from plans developed by the Boastful Sage. In exchange for his services, the dwarf was rewarded another swimsuit from the Sorcerer Kingdom to study.[10]

By the time of when a monetary workshop was hosted in Nazarick, it was stated that the dwarf was still creating inventions for the Sorcerer Kingdom.[11]

Tsuibayaya's workshop was visited by the protagonist, Surako and Sebas to pick on weapons they ordered. For the cost of the service, the dwarf stated that the development costs of his swimsuits and materials would be covered by the Sorcerer Kingdom. Seeing his friend looking down, the dwarf asked what was troubling the adventurer as the city was slowly being restored and noted the "cleansing" ritual done with his swimsuits had helped the city. He inquired about the women who wore one of the swimsuits, Clementine, which the protagonist told the dwarf that the saint was doing her best for the people, though he had frustrations on helping the become overcome their trauma of not just the mind but the body.

On the topic of fatigue, Tsuibayaya was nostalgic of his homeland's bathhouses musing that a nice dip in a bath and some alcohol would help refresh him. This inspired the protagonist to think of using "hot spring therapy" to treat the people of E-Rantel. Tsuibayaya soon found himself pressed by the protagonist for more answers about dwarven bathing customs.

Later Tsuibayaya's story of his homeland's bathhouses were passed to Momonga. It was then determined that an investigation needed to be conducted to study the dwarven baths and their health benefits. For a guide to the Dwarf Kingdom, Tsuibayaya was suggested but Momonga dismissed the idea as the dwarf while being a former local of the Dwarf Kingdom he had left the country to pursue his research swimsuits and his departure involved taking valuable minerals and goods with him which might cause some resentment by his countrymen.[12]

Abilities and Powers[]

Tsuibayaya is a dwarf whose skills are involved in crafting high-quality armor. His craft-work is noted to be impressive, by members of Nazarick who comment that the weapons he crafts are in a better quality than what most adventurers and soldiers possess. His production skills are highly spoken and regarded for as shown when he successfully replicated swimwear, using oral histories passed down from his ancestors. Furthermore, Tsuibayaya has previous experience as a warrior that even a veteran warrior from his adopted village complimented to be worthy of skill.

Main Equipment[]

  • Blacksmith Hammer: A small forge hammer he wields in his right hand.


Lakyus Alvein Dale Aindra[]

The dwarf views her to be a lousy woman as she blackmailed him to reveal his intentions when he was out searching for the Legendary Mermaid.


Their initial interaction only started out as strife between them. Due to this, he refused to give Blue Roses the armors he made for the Kingdom initially, which earned Gagaran's desire to pummel him in the face. However he did bear some form of admiration for her physical form, scouting the female warrior out as the perfect person to wear his masterpiece swimsuit and offering it to her when he saw it on her body. Even after their parting, the dwarf thought fondly of her, believing her to be a superb model for swimsuits.


Bigosa is Tsuibayaya's parent who finds his obsession with swimsuit to be foolish.

Saint Clementine[]

Tsuibayaya holds some form of recognition of Clementine. Though this is only due to her being a model for the dwarf’s swimsuits.


  • Tsuibayaya is the first dwarf character to appear in the Mass for the Dead game.
  • In his former profession in his homeland, Tsuibayaya once played a role in logistics in the Dwarf Kingdom.
  • He was briefly mentioned by Evileye while speaking to Narberal on a mission to Re-Blumrushur.[13]
  • Later it seems that Tsuibayaya lent one of his prototype swimsuits to Kyuko after she took an interest in wearing one.[14]


  • (To Blue Roses): "Oh yeah! Now, let's choose from the ones we already have. Due to the magical equipment, the size corresponds to the physique of the wearer, but it is imperative-----"
