Akechi Mizuki is a Very Strange Woman

A soon to be high school student of Sobu; A descent of Alexandria's Genesis or whatnot bought an apartment and met Hiratsuka Shizuka who happens to be her neighbour. As the title may suggest, Shizuka might gonna have a hard time, she could learn wholly extraordinary from her, or this neighbour may be as rotten as... (who?); who knows what another thing's coming for her. Be careful.
