Bokurano

There’s a claw-fisted, genocidal maniac terrorizing the planet of endless illusion, and only Van, a tight-lipped loner in a jet black tuxedo, can bring the scoundrel to justice. Armed with his shape-shifting sword and a mechanized suit of armor, Van hunts the villain who murdered his one true love. With any luck, he’ll find the man he seeks before the sun sets on civilization.

Accused of murder and thrown into the Pit, a young orphan joins a group of monster fighters with special powers to uncover the truth and seek vengeance.

When a shapeshifting demon with a thirst for human flesh, known as "youma," arrives in Raki's village, a lone woman with silver eyes walks into town with only a sword upon her back. She is a "Claymore," a being manufactured as half-human and half-youma, for the express purpose of exterminating these monsters. After Raki's family is killed, the Claymore saves his life, but he is subsequently banished from his home. With nowhere else to go, Raki finds the Claymore, known as Clare, and decides to follow her on her journeys. As the pair travel from town to town, defeating youma along the way, more about Clare's organization and her fellow warriors comes to light. With every town cleansed and every demon destroyed, they come closer to the youma on which Clare has sought vengeance ever since she chose to become a Claymore.

Yet, like all men, he has a particular weakness for the opposite sex...
