Alan "Daisuke, The Brawler" Aramaki

About

Catch phrase: "Yahoo! There's a brawl festival over there! Let me in too!"
Signature laugh: Nihihihi!

A lively guy who works for Primavera and will eagerly take part in any brawl. Both he and Keith fought in Siberia—where they had to work in a prisoners' camp—during the war and only work with each other. He's also going out with a girl named Yuki, to whom he must hide his real job… and his "pastime."
