This is Kagami from my Sailor Moon RPG. Kagami means mirror and he is the brother or, really, creator of Kyoko, which her name means mirror as well. I love naming characters! Anyways, she died, he left because he was the Guard of Sad or, in his tongue (partial Japanese really), Kanakanshii. He needed to get back to his job and restore the sadness levels in the city from what Kyoko disrupted. Yeah. It was fun.
