Help me find a game!

Hello!
I can't remember the name of an indie game that looks cool and I hope you can help me with that.
There's a word in japanese for "an obsessed girl that will do anything for her loved one" or something like that.
And if I'm not wrong, that is the name of the game (or something similar).
The game is hitman-like, I remember some videos of dragging bodies.
The developer also said that he worked in the industry before for a few years on big titles.

Do you know what game I'm talking about?!
