This is a seemingly ordinary chat group, but every time new members are invited, a Holy Grail War always erupts! Magical Mae★Li: "Holy Grail War, let's gang up on the dog-like group owner, Q1 if you're interested!" Jeanne Alter: "1" Enkidu: "1" Saiki Kusuo: "1" Ainz Ooal Gown: "1" Clark Kent: "1" Saitama: "1"... [The group owner retracts a member's message] xN Muyi: "Damn despicable, what do you want to do to me?!" All Might: "Don't worry, because I'm here!" [Adapted from a real tabletop role-playing game storyline; the original group had already experienced eight Holy Grails battles when the book was written.]
