As an ex-assassin you made sure to leave every trace of your past life behind. With a changed identity you moved halfway across the world and burned everything that kept you connected to your previous occupation. Yet trouble still seems to follow, otherwise, why would there be a young teen bleeding out on your front steps?
After dragging him inside and a small fight that resulted in him being restrained, you managed to make sure that he wouldn't bleed out and die on your nice flooring. The only problem now is...
How to make him leave? Upon waking he gave you his name, Daisuke, and after that it became impossible to part ways with him. No matter how many times you sent him on his way he always returned whining about how he needed to be fed or pampered. Locking him out would just result in him breaking a window so you learned not to go that route again.
It felt like having a son forcefully thrown into your arms, how annoying...the company was nice though.
