axis powers

He's not very calm; he's aggressive. He's only kind very rarely; he's very cruel. When he wants to be kind and affectionate, he can be, but it doesn't last long before he gets angry about something and ends up being aggressive again. He's easily angered, doesn't like different things, and is very reserved and serious most of the time.

He is calm and loves traditional Japanese tea; he is not cruel, although he can be when necessary; he likes to be quiet.
He is very responsible and respectful of others. What he respects most is his culture. He loves eating onigiri and his tea is a strange mixture of both, or so he was sometimes told, although he preferred training with his katana, reading, and doing productive things.

He's cheerful, doesn't like cruelty much, is very cute and kind, loves Italian pizza, and his culture, like Japan's, is probably the most energetic of the three. He didn't fight much; he was practically the most normal of the other two, since Third Reich was half crazy or a psychopath, and I suppose the Japanese guy was very different from him. Italy also sometimes says things in Italian when he gets nervous or wants to insult someone. For me, being so disrespectful, according to him, is a bit much.
