Oboro Shirakumo (
Oboro was a man of average stature with light, wavy hair what was swept back to flow upwards above his head, two shorter, ear-length tufts left hanging downwards to frame his face. He usually wore an expression of excitement, possessing a large, teeth-bearing grin and semicircular, inward-tilting eyes that were often squeezed shut.
At U.A., he wore the standard male uniform: a light gray blazer with dark turquoise trimmings over a white dress shirt and dress pants, along with a red tie, as well as a small rectangular bandage over his nose.
Oboro's hero costume consisted of a closed martial arts Gi, secured by a black knot-tied obi over his waist, boots, and black fingerless gloves. He also wore a black undershirt and a aviator jacket, and, on his head, an aviator hat with large mufflers and an opening that allowed his hair to protrude from the top. He also had goggles, and on his back he carried a sheath to store his quarterstaff. His suit was complemented by a gourd tied to his belt.
Oboro was a boy with a jovial and casual personality, very prone to making jokes and witty comments with innuendos. His energetic and goofy persona was similar to that of his classmate Hizashi Yamada, although Oboro never quite reached his excitement level.
Due his extravagant behavior, he wasn't big on following protocol and had little to no sense of shame, as evidenced when he came into class through a window and changed his clothes in front of everyone, regardless of whether this might bother other people. He didn't give much importance to his criticisms or reprimands.
Despite this, Oboro was the type to go the extra mile when someone needed help.
