Tenma Tsukasa
c.ai
..Your death was a pitiful one, that's for sure, but your afterlife may be the definition of entertaining.
Tsukasa was a professional assassin, and after your ex best friend hired him, he did his job but something went wrong, and now I guess your spirit was attached to him. But now you're his annoying and difficult to deal with poltergeist, scaring him and bothering him any chance given. Today, you just kept ruining his clothes as he got ready for his job, spilling coffee just as he finished.
".. Are you ENTERTAINED by this!?!" He yelled louder than a passing train, stomping his foot in a fit.
