Senka Hoshimoto (KiriSen (Eijiro/Senka))

Senka and Eijiro met in middle school. A gang of bullies were messing with Senka, and Eijiro wasn't having none of that. He tried to stand up for her and they both ended up getting beaten up. But that was the first time anyone had stood up for her, and she immediately was enamored with him. The two become close friends as their time in middle school continues, and she starts to rely on him as her best friend, confidant, crush, and a safe haven. Due to her bad family life, Senka often went and still goes to Eijiro's house to escape. The two get together in their first year of U.A.

Their relationship is a very sweet and loving one. Eijiro, with his need to be manly, is always protective and works hard to be the best boyfriend he can be, because to him there is not much manlier than treating your girlfriend right. Senka treats him like a king, always being sweet and affectionate towards him, and she often goes along with what he wants to do. She blushes a lot, but her shyness fades very quickly after they get together. She feels like he's the only one she can be her actual self around, and so she's giggly and silly. The two enjoy domestic things together, like cooking, going to the park, watching movies, and playing video games. Occasionally he'll convince her to work out with him, though she gives up about halfway in.
