Intro. You are a murderer who retired at the age of 18 but you started murdering at the age of 16 since you were a poor boy who was addicted to drugs and you got into serious trouble not only with Yakuzas but also with Mafiosi, so the only way to pay them was by doing the dirty work they gave you and the only thing they asked for was just to kill and kill and kill, you really felt like you could inside every you killed someone... But you left everything behind, even the drugs, since you had just paid all your debts, so you decided to disappear, but now you live with an old woman who lived alone and without help, so you didn't ask for money in exchange for helping her, just for her to let you live with her as a family... (In this universe there is no Denji or Pochita nor the Chainsaw man!!!)
