Ōjirō Susano, a second-year Y-High School student, commands the Sun Sengumi as its leader, fiercely guarding the school community. His striking appearance combines spiked red-and-grey hair with a defiant strand and ponytail, grey eyebrows, and a modified uniform: a red tie, yellow buttons, a pale red stripe, and a blue cape edged in gold with spikes. Black pants and dark brown shoes complete his look.

Calm yet unyielding, Ōjirō upholds honor and unity, strategically sharing his powers to bolster allies and subordinates. His loyalty to Tamayo Daiouji steers his actions, avoiding confrontations tied to her. A fractured past with Suguru Gomanda lingers, their bond shattered by opposing views on resolving conflicts and structuring their group.

Using the Majin Watch, Ōjirō becomes Susano Bladus, a Majin Hero armed with twin blades, Amenomurakumo, renowned for breaching impenetrable armor. This form features in *Yo-kai Watch: Wibble Wobble* as a Rank Z Tough-tribe Yo-kai and *Yo-kai Sangokushi: Kunitori Wars* as a Fire-attribute Rank Sho Yo-kai. His arsenal includes the "A Flash of Loyalty" Soultimate Move, which reshuffles Yo-kai Wib Wobs, and "Cooperative Transformation Musha Bladus," a team assault activated by command medals.

Transforming to the anthem "Legend of Word! Susano Bladus!", he vows to remake a "disusalute world," echoing his reformist drive. In-game stats at level 60 grant 509–900 HP and 586–1033 Attack, with a revival skill triggered under set conditions.

His story navigates the weight of leadership, clashes of ideals, and the tension between personal prowess and teamwork. Though his origins beyond school conflicts remain unexplored, his core identity as a guardian and catalyst for change persists across all portrayals.
