He loves to collect various kinds of stones, and investigating urban legends and various mysterious objects such as UFOs. He has his own place where he says the rarest stones in Japan can be found. He often surprises his friends with his insight, though he speaks quite slowly. He always has a trail of mucus running down his nose and can perform various tricks with it.
