adj.A person who is initially loving, but then becomes mentally unstable over unforeseen trauma, using violence and / or anger as an outlet for their emotions. Stems from 'yan', which stands for mental illness and 'dere', which stands for affection.
Yandere Kanojo isn't quite accurate, if you're trying to describe the main lead. She's more like a tsundere rather than a yandere…unless she's planning to lash out and kill the main guy at the end (which I hope she doesn't).
Ryuuzaki Reina is your typical high school thug. She's a leader of a gang of female delinquents, and touts an equally fearsome exterior. One day she meets Tanaka Manabu, and the pair instantly fall in love with each other. Unfortunately for Manabu, she can't fathom anyone finding out that she's a young maiden at heart, so they have to keep their relationship hidden.
This manga started back in 2009 and is currently on-going. It's a 4koma gag manga in the style of Lucky Star, Azumanga Daioh, and K-ON!, and is probably my current favorite guilty pleasure. There's so many quirky hijinx the two star-crossed lovers fall into, that I can foresee this manga running for a very long time — which I'm equally happy to admit!
By far the most interesting character of the bunch is Manabu's younger sister Mayami. Never before have I seen a girl with such an extreme fetish! Mayami's an 'm' or masochist, which means that she extremely enjoys being verbally or physically abused — which Reina has no problems obliging. Anytime she pops up, there's only trouble (and lots of laughter) that ensues!
Kinda reminds me of Kanbaru in a more ecchi sort of way.
There's only a few chapters out there. Hopefully someone will pick it up and continue the translations, as this is one story that'll keep you wanting more. If you're in for a quick read for something light and extremely humorous, check out Yandere Kanojo!
