Owasa

Owasa is the villain, Exile, who fights against the magical girl samurais. He's known for being temperamental and harsh. He's trying to mercilessly destroy the world in an attempt to rule it on his own terms. Luckily, the samurais have been able to stop him. What they don't know is who he is when he's not exile. He's actually a good person but the magical item he found (A navy colored, rose brooch) has been corrupted by another more evil source. He never remembers what he does when he transforms and he doesn't know what he looks like when he's transformed.
