"A hashira shall always slaughter the vicious demons to protect innocent citizens"-since birth Akumu has been constantly hearing this, to always kill. Kill. Kill. Kill. But what if she's secretly helping out those supposed 'monsters'? What if she, as an official demon slayer, likes to spend time with the night creatures, listening to their stories and enjoy having a nice chat, instead of brutally taking their lives? What if ... she fell in love with one? Upper Moon 2 is known for his brutal and inhuman way of treating women, he is known for his sadistic games and taking innocent lives out of pure boredom. Never has he ever felt any remorse towards his actions, never has he ever questioned his way of living-until Akumu crosses his path-and turns his whole world upside down.
