Inasa Yoarashi/Synopsis

History
When he was young, Inasa admired the Hero Endeavor because he symbolized his belief that all Heroes have "hot spirits". The young Inasa tried to get Endeavor's autograph, but Endeavor refused Inasa's request and told him not to stand in his way. Inasa felt betrayed by Endeavor's unheroic behavior and his admiration for Endeavor slowly turned to hatred.

Inasa participated in U.A. Entrance Exam the same year as Izuku Midoriya. During the exam which consisted of a marathon, Inasa spotted Shoto Todoroki and became interested in him after seeing his great usage of ice; although Inasa had a bad feeling coming from Shoto, he felt reassured that once they became classmates, Shoto's eyes would not bother him. Inasa and Shoto reached the goal but Inasa reached the goal first by a stretch, making him the first to cross the finish line while Shoto came in second.

After the marathon, Inasa approached Shoto and praised him. However, Shoto dismissed Inasa just like his father and told him that he was a nuisance, which shocked Inasa. Inasa received the top score and passed. However, he declined U.A. High School's admission. Instead, Inasa enrolled into Shiketsu High School.

Provisional Hero License Exam Arc
Inasa joins his fellow peers from Shiketsu High at the Provisional Hero License Exam site, Takoba National Stadium. Inasa overhears Class 1-A students about to cheer "Plus Ultra" and decides to emphatically join the chant. He explains that he loves U.A. and tells the students it will be an honor to compete against them.

Seiji Shishikura scolds Inasa for crashing their chant and Inasa apologizes in the strangest way possible. He slams his head into the ground and loudly projects his apology. Camie comments that Inasa's head is bleeding and he replies that he likes blood. Seiji tells them both to follow him into the arena. Shota Aizawa tells his class that the energetic student is Inasa Yoarashi, the young man who came in first in U.A.'s entrance exam for recommended students.

During the first phase of the exam, Inasa is inspired by other students battles. In the city district of the arena, Inasa stands on a tall building and uses his Quirk to collect the balls of many rival students. He asks if he can join the fun and then reigns down a barrage of projectiles on his opponents. Inasa manages to eliminate one hundred and twenty students at one time and becomes the first competitor to complete the first phase.

At the end of the first stage, while the approved students rest, Shoto Todoroki confronts Inasa and asks if he has done something to him, since Inasa has been acting strange towards him, and Inasa tells him that he hates him and his father.

At the start of the second phase of the exam, Inasa starts his rescue using his Quirk to move the rubble and the people under them but is cautioned by supervisors for being too careless. Shortly after, Gang Orca appears playing a villain role in the exam. Inasa is one of the first students to confront him and tries to use his hand to attack the villains but Shoto's fire gets in the way, nullifying both attacks. Inasa and Shoto argue. Inasa mentions the reason he hates both Shoto and his father. Both end up being defeated by Gang Orca and his group and failing the exam.
