[color=a187be][u][b]Name:[/b][/u][/color] Ushiyama Shifumi (牛山 白笛美)
[color=a187be][u][b]Alias:[/b][/u][/color] Ushi-Oni (牛鬼)
[color=a187be][u][b]Age:[/b][/u][/color] 37
[color=a187be][u][b]Gender:[/b][/u][/color] Female

[color=a187be][u][b]Appearance:[/b][/u][/color][indent]Shifumi is slender and over two meters tall with sickly, pale skin. Due to metabolic stress and age, she has white streaks in her hair, which she styles to look reminiscent of horns. She normally wears an apathetic poker face, but when she smiles, it is gentle and sinister. She exudes an oppressive aura and pins people with black, lusterless eyes. She hunches often to listen to people shorter than her speak.

Like most Yakuza, she has tattoos, the most prominent being on her back, hidden from view, of her namesake.

Due to the nature of her quirk, Shifumi's muscles are embedded with special staples, but the accrued bio-toxicity has caused a blackening discoloration of the skin around the staples.

On the field, she tends to wear a set of black metallic armor with white trimmings.

[color=a187be][u][b]Personality:[/b][/u][/color][indent]The spine, the foundation, Ushiyama Shifumi presents a facade of immovable strength. She speaks softly, but with weight, keeping her expression placid and her thoughts and emotions close to her chest. During confrontations, however, she is brutal and relentless, preferring to end the confrontation swiftly. To those close to her, she can be motherly in a tough love sort of way, but for the most part, she doesn't let people get close emotionally because she knows that she has too much to lose if such weaknesses ever got exploited.[/indent]
[color=a187be][u][b]Background:[/b][/u][/color][indent]Shifumi and her mother grew up in destitution. While heroes protected people from physical dangers, like natural disasters and villains, nobody was going to save anyone from financial inequality. In the dark, seedy underbelly of society, overlooked by humanity's 'saviours', Shifumi had to fight to protect what was hers. It wasn't long before she joined a small street gang to protect her neighborhood, moving from one organization to the next based on the perceived strength of the organization. Soon she found herself as the local enforcer of her current Yakuza group. As long as she continued to serve with distinction, Shifumi and her mother's lives were decent, some might even consider luxurious. But in addition to being just muscle, Shifumi was a fast learner, and demonstrated the 'heart' of a Yakuza with her loyalty and dedication. Eventually, leadership of the local group passed to her. At some point, Shifumi's mother passed away, but she passed away in comfort. But now Shifumi had a bigger family to take care of.[/indent]
[color=a187be][u][b]Aspiration:[/b][/u][/color][indent]Shifumi's loyalty, first and foremost, is to her Yakuza group. She desires to keep them and their families safe and well-fed, even if that means going up against heroes, and other villains. Due to the rise in heroism and villainy, the Yakuza has seen tough times, and Shifumi hopes that the villain who has contacted her, and the challenges he has presented her with, will give her and her group legitimacy in the eyes of other villains so that they can cooperate against the forces that seek to suppress their collective ambitions.[/indent]
[color=a187be][u][b]Strength & Weakness:[/b][/u][/color][indent]Besides her quirk, Shifumi's greatest strength is her organizational leadership and willingness to negotiate, a rare trait in a world of egotistical, self-important villains. She can take a step back and consider what the more pragmatic options are, instead of letting her pride take the reins. Her greatest weaknesses are actually her ties to her Yakuza group. Members getting taken hostage is not something she can ignore.[/indent]
[color=a187be][u][b]Quirk:[/b][/u][/color][indent][i][b]Do You Even Lymph, Bro?[/b][/i] - When Shifumi has an immune reaction, her white blood cells release a strength-enhancing chemical. By embedding bio-reactive staples into her musculature, she ensures that her body is in a perpetual state of bio-rejection, and thus operating at maximum strength all the time. She also regularly draws her own blood and, using her Yakuza group's medical facilities, extracted the serum, which her allies can consume as a temporary strength boost.

[color=a187be][u][b]Skills/Talents:[/b][/u][/color][indent]As the leader of a Yakuza group, Shifumi has management, leadership, and diplomacy skills. She also has quite a bit of capital to back her up. Being a bit of a traditionalist, Shifumi has exposure to various forms of Japanese martial arts, though her forte is jiujitsu.[/indent]
