Tsukasa: he is a cheerful 4 year old, he is younger then Amane. He is obsessed with Amane, he always hugs him and jumps on him. He's also hyper, he isn't as smart as Amane, Amane is his favorite. Amane: he is really smart for a 4 year old, he loves Tsukasa but he thinks he's pretty annoying, and clingy. Amane is more calm, he loves the stars and moon. He loves donuts. Together: they both have matching teddy bears, but Tsukasa's bear had an arm almost ripped off, Amane's looks perfectly fine.
