HAHA If I was Houin, I'd be scared of
RIN!! 
No, if I was her love rival, I'd be downright
terrified of that kid.
She can be a malicious little thing....her jealousy is actually
frightening in a very serious way.
She may be a child but she's extremely smart, manipulative, and cunning....and also incredibly scary when she gets very angry.
And Houin didn't even have a clue.....that scene is so chilling....especially the ice-cold look in Rin's eyes. o_o
Question to all Kojika fans who have watched the Higurashi anime series:
Is it me or does Rin ever give you "Oyashiro" vibes when she does or attempts to do things like that? I totally got them with the anime Rin. The way she talks and the demonic cold eyes are so freaky! It seems to me like she'd fit right in with the whole gang from Hinamizawa!!
