Bloody Love Maiden

Bloody Love Maiden is a game event that occurred in Mass for the Dead. It was released on February 12, 2020 to February 22, 2020.

Background
One day Shalltear Bloodfallen while patrolling the Rift at the Throne Room, daydreams about her and Momonga and being lovers. Her idealistic reality is interrupted by her two Vampire Brides who inform her that the Rift is about to undergo a Chaos Zone. Annoyed that she was brought away from a nice place, she dons her armor and readies for combat. After wiping out all the swarming Chaos Beasts, her subordinates praise their master on her job in wiping which Shalltear soaks in. She wonders aloud why Momonga has not accepted her love to the confusion of the vampires. Having a realization sh excuses herself and locates the protagonist and Slimeko in Ashurbanipal. Making sure that Albedo is not present in the library, Shalltear demands to know what the protagonist thinks of the results on the Princess War. Since the final decision couldn't be made by Momonga as both Albedo and Shalltear tied in all competitions, the only one who can answer that is Momonga, but unfortunately left the outcome inconclusive.

But Shalltear believes that the reason why Momonga did not choose either of them was because of their lack of power. She insists that it is a test and hidden test that their master has laid out. The protagonist thinking on this admits that an issue like this for the future of the Great Tomb of Nazarick is too important to be left unresolved. Thinking this to be a "Trial of Love" Momonga is waiting for a woman you expresses genuine love. The protagonist finds a precedence in an anecdote, "The Three Visits", where Liu Bei succeeded in recruiting Zhuge Liang after paying three personal visits until at last Zhuge Liang accepts to join Liu Bei due to his patience. Thinking this leads to proof of such a trial the protagonist and Slimeko pledge to strategize a way to win Momonga's heart for Shalltear. To avoid complications with the other Floor Guardians, they develop a cover story to spend time outside of Nazarick to "teach" Shalltear tactical knowledge.

Incident
Now that both Momonga and Albedo are under the impression Shalltear wishes to go outside Nazarick to undergo training, the trio commit to themselves in helping Shalltear pass the Trial of Love. Later Momonga summons Shalltear to handle an outbreak of fly-type Chaos Beasts in the vicinity of Nazarick. Though the creatures are not that far from the dungeon, Momonga worries of them attacking human settlements, and may cause refugees to flood in the area which will allow Nazarick to be discovered. Shalltear accepts the mission and departs. Momonga noticing Shalltear's lacking lewd behavior when usually talks to him, asks Foire if there is anything strange with the Floor Guardian lately. The maid on duty cannot say but suggests maybe keeping her emotions in check for the mission and perhaps she is just taking her duties seriously.

Outside tomb, Shalltear prepares to get ready for her mission and is excited that now she can begin the first stage of her operation "Attracting the Attention of the Target". This mission given to her is the perfect way which her two comrades Slimeko and the protagonist agree. They are later joined by Narberal Gamma and Entoma Vasilissa Zeta who have come to support her during the mission to purge the Chaos Beasts. Shalltear however insists that they observe while she deals with the monsters. Surprised by her request the two maids consent to her order as it will be a good lesson to watch how Shalltear fights. The three women take to the air in the sky.

Back in Nazarick, Momonga observes the three via Mirror of Remote Viewing with Slimeko and the protagonist. Whilst Shalltear singlehandedly slaughters multiple flying Chaos Beasts, Momonga cannot help but admire her skills and speed. Slimeko watching Momonga's growing interest is pleased. The former notices and asks if something is the matter, but the slime quickly directs his attention back at Shalltear. With that Momonga asks if the two noticed any new changes in Shalltear's behavior as she was not her usual self and was worried she was dissatisfied at something. The two delicately dodge the answer stating that Shalltear just wanted to regain her levels. Hearing that Momonga thinks that this exercise should solve that issue for Shalltear but decides to ask her directly when she returns.

In the air Shalltear's onslaught attracts the attention of a Giant Flying Chaos Beast as she has been killing its minions. Excited at the beast, Shalltear declares to take the opportunity and capture it as experimental material for Momonga. After weakening it enough, Shalltear orders the shocked two maids to bring it back to Nazarick. When she returns to Nazarick, Momonga congratulates her on her successful hunt.
