The strongest weapon in the universe wielded by legends

Issei or more commonly referred to as the heroes weapon is a ring that can change shape into a weapon that is unimaginably sharp and unbreakable, over the years issei gained new abilities like bow aura, sword aura and other types of weapon aura but he was forgotten by time sealed somewhere, after years of being sealed he eventually gained a conscience or his own will, a few more years after he gained a human form so issei just sat there all alone with no one to talk to
