Thirty-two 7's

Mari has never been able to feel any emotion ever since birth. Everything changes when she finds herself in a unfamiliar place. There, at the so called "school", Mari is able to feel emotions once again by sponging up the leftovers from the Devils and Angels. There are 14 of each, girls and boys. She begins to fit in, making friends and getting her own harem. But nothing lasts. Soon, she begins to recall memories of others and her own twisted past lives . A fated day soon will arrive. It will either become her life or it will utterly destroy it. Lies and unanswered questions build the very school. To dark or to light, someone must cage the ravaging emotions that roam the schools. It turns out Mari is the only one to do so, for the others before have turned their backs.
