Kirishima and Kaminari were friends, but each wished it was more. In high school, their days were happy and content. Now, they haven't seen each other in four years, and they are adults now.

Kirishima worked in a hero agency with Tetsutetsu, and often with Momo, like in high school. But he can't help but wonder about his high school crush, that loving yellow-haired boy.

One day, he hears about transfers to a new agency. He's thrilled about the agency base in Osaka and takes the transfer.

The day Kirishima got there; he saw the back of someone's head in an office next to him. He recognized the black lightning streak on that yellow mess of hair as the boy turned his head. He felt his eyes widen. "Denki?" He called out as he walked over, ruffling his own sleek red hair in his hands slightly.
