Oboro Shirakumo

Oboro Shirakumo was a student in Class 2-A at U.A. High School, training to become a Pro Hero at the same time when Shota Aizawa and Hizashi Yamada were also attending.

History
On his way to start his second-year at U.A. High School, he finds a cat that Shota Aizawa left an umbrella over. He takes the cat and the umbrella with him to class. Oboro arrives through his homerooms window using a cloud he made using his Quirk He gets in trouble from his home room teacher, and insist he use the door like everyone else. Soaked from the rain, Obero interrupts roll call and ask if anyone has a towel with no success. He also ask Shota if he dropped his umbrella and hands it back to him. With his clothes all wet he decides to change to his gym attire in front of everyone. This causes the classmates to shriek but he censors himself with a cloud. He pulls out his new friend, the cat, and everyone falls in love with it. Now dressed places the cat on a cloud pillow and lets roll call continue.

Joint Training Arc
After the U.A. faculty conference, where Hitoshi Shinso is officially admitted to the Hero Course, Present Mic brings up Oboro to Shota as they are walking down the hallway.

Quirk
Cloud: Oboro has the ability to manipulate water to form clouds. The full potential of this Quirk is unknown, however, given that Oboro was in U.A. High's hero course, Cloud is presumably useful in combat and/or rescue. He is capable of moving through the air by creating clouds and riding on them.
