Takeshi Kino

Zwei was an ordinary person, until one day, while walking the streets a night, he witnessed a brutal assassination. He managed to avoid the sniper, a young girl named Ein, but was soon captured, and had the memories of his former life erased. He is spared death only by accepting a condition: to train to become an assassin alongside Ein. Now he must find a way to free himself from this shady world and reclaim his life once again.

Hazumu confessed his love to Yasuna, but she turned him down. To ease his heartbreak, he went to Mt. Kashimayama where he had met her for the first time. He loses his way in the mountains, and it starts to get dark. Seeing a big shooting star in the sky, he begins to formulate a wish, but quickly notes that something is very wrong. For the shooting star is actually a space ship about to crash into him. And then he died. Only with the help of the aliens could his live be saved. However, he became a girl, due to an accident during the reconstruction of his body.
