Ōtenta (大典太, Great Law Plump) is one of the Tenka Goken.
It seems to have the same ability of sword creation as Togusa.
Actual Historical Ōtenta Mitsuyo was created by swordsmith Miike Mitsuyo and is famous for it's magnificent Sugata. A legend says Oda Nobunaga tested the bravery of some of his retainers by going onto an haunted place. Maeda Toshiie wielded it when it was his turn, a gift of Hideyoshi to protect his friend against those supernatural phenomenons. And indeed, the evil spirits didn't appeared before lord Toshiie. They fled the keen edge and spiritual powers of Ōtenta, or so it is said.
