|Club||Student Council President|
|Friends|| Ryōko Kaji (Girlfriend)|
Masafumi is a fair-skinned teenage boy with short dark-blue hair that has bangs covering the left side of his face, violet eyes and oval-shaped eyeglasses.
Akagi is a passive aggressive lover with a little too much sass, but he is really smart that he and Ryōko Kaji have complement each other very well.
Ryōko is Masafumi's girlfriend whose relationship with her is confusing, but it has a great story to it. He often teases Ryouko, much to her annoyance and their dynamic is pretty consistent: she is raging and he is taming.
Shinichi is one of Masafumi's friends. It is said by Shinichi that they should never keep secrets from each other, and even hits Shinichi when he finds out that Shinichi had been repeating years and kept it secret from him.
