Rei lives with her grandfather at the Hikawa Shrine, where she's a shrine maiden. Rei's mother died when Rei was a young girl. Her father is a politition for the Democratic Liberal party in Japan. He doesn't care about anything but politics, and part of the reason Rei's mother died is because he was neglecting them. That's why Rei moved in with her grandfather. Her grandfather is a pervert, but he's sorta powerful. Think Ranma 1/2's Happosai, just less perverted, and less powerful. He looks up the rest of the girls skirts sometime which I find amusing. He probably gets his power because of the fact he was one of the seven shadow warriors. Amoungst all his flaws however he's still smart enough to love Rei dearly, and, though she might get sick of him eves- dropping and his perverse way Rei loves him as well.

Get Out Of Here, We're Meditating, GO HOME! or if you wish to the corridor of characters.
