You can also click on the character's tags after you click on a manga featuring the character, i recommend clicking on akabane karma's tag for a nagisa x karma, karasuma x karma or even kayano x karma dj associated with the tag

I REALLY WANT TO FIND ANYTHING ABOUT NAGISA X KARMA ┗( T﹏T )┛

Scarred...so scarred...otherwise, um, guilty pleasures?(づ ̄ ³ ̄)づ

SERIOUSLY, does anyone know a place to read translated Ansatsu Kyoushitsu yaoi doujinshi! I know they must exist somewhere..... >< KarmaxNagisa is just too perfect
