Yoji is a mystic afflicted with hyperreligiosity. He is often found wandering around, sharing his insights with anyone that will listen. He's mostly harmless, and people tend to pity him, so he is generally decently fed and obliged. Some people think he has Waxman-Geschwind syndrome.
Quotes:
"Well, you see, the actual etymology of the word 'want' is based on the sound a baby makes as it cries. Waaaa, it says, it wants something." - Yoji
