When I first watched Gravitation I over looked Ryuchi for a few of the others characters. He was just the crazy singer who spent all his time SD. I didn't even realize he was himself half the time. The second time I watch Gravitation through, he finally caught my attention and rapidly became my fave character on the show.
I love his super genki, SD side. It's fun to watch a thirty year old man jump off buildings and carry around a stuffed pink bunny. His more serious side is rather frightening though. He becomes so cold and professional, almost like Yuki. *shivers* I don't know which side is really him. I don't think anyone does *sweatdrop*
He has something going on in his head though, and he knows all the ways to get Shuichi to do what he has to. I think he's 100% in control of his various personalities since he switches back and forth so quickly. Maybe a little bit of concentration is needed to bring on the more serious ones and zero thought what so ever for the really out there ones. *shrugs* All I know is I like him best on his in between side best. When he's relaxed and "normal" (althou normal is a questionable word when it comes to Ryu-chan...)
