Age:  15
Medical Info:  Very healthy; heals a lot faster than he should, but that's probably just the Dying Will Flame.
Abilities:  He's handy with a sword. He's also a natural-born assassin -- which means it took him about a year to get from 'baseball freak' to 'widely known and respected Rain Guardian'. He can irritate anyone to death just by being his friendly, good-natured self. He's damn good at baseball. Oh, and he can make sushi.

Notes for the Psychics:  Yamamoto is either a Genius Ditz, or a master of cheerful Obfuscating Stupidity. Maybe a little of both; maybe a lot. You'll probably catch different things at different times.
Can I shapeshift/bodyswap/spit at/step on/etc?:  Sure; just contact me first for the big stuff.
Maim/Murder/Death: I'd prefer if you asked me first, but it would be interesting. ;)
Kissing/Hugging: It's all good. |D
Cooking: He works at his dad's sushi shop, but he's probably not too familiar with foreign cooking.

Threadjacking: Sure!
Fourthwalling: Haha, go right ahead.
