Ah. I deleted it a few months ago because I wasn’t really updating it very much. One of the few ones I regret deleting. :(
I disagree. Shion’s a yandere. She’s acting out of love for Satoshi. Rena’s a yangire, though, yes. She’s acting out of friendship, love of her dad and self preservation. That only really leaves Satoko and she’s not really either - she’s sick and abused.
