Mt. Kamui

Mt. Kamui is the het ship between Yu Takeyama and Shinji Nishiya from the My Hero Academia fandom.

Canon
Yu and Shinji are both introduced in the first episode of the anime as Pro Heroes Mt. Lady and Kamui Woods. They both fight the villain that had appeared in the city, but Yu, who is making her debut as a hero, ends up getting all the credit for taking him down, which Shinji is not happy about.
