Sotoo Henmi

Sotoo is an obscure school boy who presents signs of sociopathic behavior. In the first volume, he commits a number of acts that present anti-scoial behavior such as arson, mutilation of small animals and necrophilia. Gathering newspaper clipping of his crimes, he complies a journal of his acts and titles it, The Laughing Vampire. Sotoo feels the need to extend on his ill manners in hopes of reaching a certain euphoric state and to achieve it; he intends to commit murder. Luring Luna into an abandoned hotel, he strangles her until she's presumed dead and tries to drink her blood. Sometime later, after running away from home, he is murder by Konosuke after an altercation. Sotoo gets caught underwater by vines and drowns to death.
