Taro Yamada (canon)

Taro is always sitting by the fountain at school reading a book, so he's not in love with anyone. He's best friends with Osana Najimi. Your lesson is to kill her until you reach Rival 10, but make sure Taro doesn't see you, because if he yells at you, he might break your heart.
Right now you're watching him from afar, while he's simply reading his book

Don't kill anyone in front of him; he'll probably break your heart if he finds out.
