wow, i see that you're pretty goddamn far into this. well, just read this if you wanna.
Name: Adorin Arin
Age: 14
Gender: Female
Appearance: She has jet black, long, drooping hair that reaches to her waist. While doing the adrenaline thing, it sticks up like she's a super saiyan or some shit, minus the change in color.
Personality: In her normal form, she's lazy, sarcastic, antisocial, and such. She really just wants to go home and play video games, and has no actual close friends at the school besides a few. While she's in her adrenaline-boosted form, she becomes fiery, competitive, hella aggressive, and energetic.
Quirk: Adrenaline Junkie: So, adrenaline gives Adorin a massive boost in condition. This ups her energy, strength, stamina, speed, reaction time, such. She also keeps her usual intelligence while using the quirk. After the adrenaline wears out, however, she becomes stricken with fatigue for about an hour or so.
Weaknesses: There is a 2 hour time limit for this quirk to take affect. Due to her newfound fiery nature, Adorin may also make poor judegments and not strategize. Like, at all.
Costume: She wears a sleeveless sweater and under, a sleeveless shirt. Both are made from a special fabric that grants light blast resistance to the torso. She also wears a red and black masquerade mask and tight black pants, all the better to move around.
