@paperweight04 Alright here it is
Name: Kazami Bakugou
Quirk: Thermodynamics.
Allows the user to change the atmosphere temperature either to make it hot or cold. User can also use the quirk like Half Cold and Half hot. But not limited to either side.
Limits User at most can go to the temperature of 500°C and -20°C if he goes either above or below. He will have massive damage on his body. User can only control the temperature of area around 5 meters.
Story: One of the distance cousins of the Bakugou family. They were considered a black sheep of the family and they were tormented for it. They had a sad life in school and they had their crush stolen by Masaru as they liked Mitsuki but they didn't know that Mitsuki liked Masaru. They were belittled due to their quirks and weird looks. (Imagine he looks like Gyutaro of Demon Slayer, Daki brother upper moon six). After the start of culling game, he gained a boost in their quirk allowing them to use it like half Cold and half hot and they promised to get Mitsuki back from Masaru and will do anything to get her.
Honestly this came to mind as I read a chapter of fic by the name of Quirk Cultivator. You should read it, it is funny.
