Description
Born Toshitada Koma in 1551 Kyoto (then Yamashiro Province) during Japan's Warring States period, he fought as a young lord to protect his lands and harbored ambitions of unifying Japan. Frustrated by his clan's limited power, his growing impatience drew the attention of Arago, ruler of the Netherworld. Arago promised dominion over humanity. Between ages 11 and 14, Toshitada accepted, abandoning his clan and humanity to become one of Arago's four Masho: the Oni Masho. His body and spirit were fully corrupted, sealing his original identity.

As the Oni Masho, he served Arago's invasion of the human world, commanding the Armor of Cruelty (Oni armor), representing spring and associated with the ogre. Considered the strongest Masho and embodying loyalty, he adhered to a personal code of honor, favoring direct combat over sneak attacks and despising mediocrity. Repeated failures led to his demotion from leadership. His true self remained suppressed under the control of Badamon's Jiryoshu spirits, further entrenching him in Arago's forces.

A transformation occurred when the Ancient One, Kaos, intervened, guiding him to reconnect with the inherent virtue within his armor. Opening his heart broke Arago's control, restoring his memories and human spirit. Freed from corruption, he chose Kaos's path. He allied with Nasutei and Jun on a critical mission to retrieve the Jewel of Life, one of three sacred objects essential to defeating Arago. During this quest, he formed bonds with the Ronin Warriors, becoming integral to their group. He ultimately sacrificed himself using the Jewel of Life to free Kayura from Arago's influence, cementing his legacy as a redeemed warrior.

Physically, he stands 173 cm tall and weighs 67 kg, with red hair and blue-green eyes. His body bears scars from human battles and metaphysical corruption. Post-redemption, he adopted monk attire and wields a Shakujo staff for protection, transportation, and spiritual purposes. He enjoys reading, writing, and self-improvement, and dislikes beans.

In battle, his primary weapon was the Yokoshima Oni Kama, a kusari-gama featuring a sickle attached to a chain with a clawed weight. His signature technique, the Ko Rai Sen, manifested as a flash of crimson lightning. This attack exploited the chain, often involving the clawed weight burrowing underground before erupting to entangle and electrocute targets with red electricity. His armor granted immense physical strength, capable of sending opponents flying with punches.
