Well, awhile ago, I read this manga...here is a lil' desription...there is a main character is is stuck in jail for some crime and ther are 4 bosses of the jail, north, sout, east, west...and its about how he becomes stonger? and faces the henchmen or the bosses and the bosses themselves............anyone know the name of it??

You're in luck, i was reading the description of this manga just yesterday, i'm pretty sure it's Riki-Oh.

Common sense just isn't that common

Oh....my...gosh I can't believe i forgot the name....wow....thanx!!
