Daigo is a middle-aged man with lightly tanned skin and a round head that appears to merge into his thick neck with little distinction. He has small, black eyes that always remain closed, set close together on his face, notably small eyebrows and a visibly hooked nose. His dark hair is very short, and is worn in a round shape on the top of his head with two stripes of hair, that go around the back of his head, visible below.
Like the rest of Wolfram’s minions, Daigo dresses in a black combat suit, complete with a full-face mask, a paler X-shaped design patterning it over his face.
Daigo appears to be a loyal henchman dedicated to Wolfram's cause. He enjoys fighting and commends those who know how to fight well. Daigo takes pride in his own abilities as well, and despite disliking being underestimated, his arrogance caused him to underestimate Katsuki Bakugo in battle.
Daigo is present alongside all of Wolfram's men when they sneak into I-Island. After setting their plan into motion, Daigo and the others restrain the security guards and take over the Central Tower control room. They follow Wolfram's orders and turn I-Island's security on its citizens, tourists, and Pro Heroes.
When U.A. students start ascending the tower in an attempt to rescue the hostages, Wolfram sends Daigo and Nobu after them. The duo reaches the 80th floor and notices Katsuki and Eijiro there. The latter tries to explain they got lost, but the villains don't believe them. Nobu attacks, but the villains are quickly frozen by a surprise attack from Shoto Todoroki.
Nobu frees the duo from their icy prison and Daigo transforms into a hulking purple beast. He breaks through Shoto's next ice attack and even shakes off one of Katsuki's explosions. His counterattack sends Eijiro flying into a far away wall. He admits the other two boys know how to fight pretty well.
Unnamed Beast Form Quirk: Daigo's transformation-type Quirk gives him the ability to enlarge his body and shift into a gorilla-like purple beast. This grants him increased strength and speed. With his Quirk active, Daigo could shake off Katsuki's explosions and break through Shoto's ice with brute force alone.
