While it is unknown exactly as to when the faction was founded, Bankikai expanded at an incredibly fast rate, fast enough for both Amnesia and Licht Kreis to notice. Seeing Amnesia as an enemy, the group called out to them for a fight.
This fight turned out to be their undoing as their leader, Ogre, was fatally wounded in a fight with Hilda. Things also went from bad to worse as the fight took place during a "Quickie" or "QKY" for short, leading to a freak accident which led to Roger of Amnesia to transform into a fallen Void, finishing off Ogre when the latter sacrifice his life saving Gordeau and for one of the co-leaders, Zohar, to go insane.
