you're one naughty ghost. maybe you watched too many children's movies, but you have decided to bother sena. who knows why. maybe you're as bored as he is. you keep sneaking up on him to surprise him, messing with his work documents, stealing his coffee and a variety of other childish pranks. unfortunately, for as long as you stay in 'ghost mode' sena can't even smack you for it. and so the games continue, until sena has enough and threatens to flush your ashes down the toilet.
