Kaito Aizawa (藍沢 海人 Aizawa Kaito) is a student of Hiiragi Academy's main campus, and is the established leader of Team Blue Corps. As someone who greatly enjoys Junichirou's work, he is given the nickname "Self-Proclaimed Fan."
A game-loving third-year S-rank student, the leader of Team Blue Corps, and one who considers himself a huge fan of Junichirou Kagami. He first appears alongside Tendou as they watch, from afar, Junichirou’s group defeating Team Titan in soccer; looking forward to Blue Corps’ eventual encounter with the teacher.
The time comes when one of his team members, Daiki Kuujou, catches the attention of Junichirou as he tries to burn the farm crops of the Noble Garden Team. Aizawa appears before the two, and, after making a bet with Junichirou to gain one of his female students, forces Daiki to accept Junichirou’s challenge as it would be rude to overlook a challenge from someone lower ranked. He watches from the side as Daiki loses in a match of water polo against Junichirou; revoking Noble Garden’s expulsion, and asked for everything regarding their bet to be invalid.
It is here that Aizawa makes a proposal; for his Blue Corps Team, and Junichirou’s Ichou group to join forces. However, Junichirou refuses the offer and forces him into the water; “teaching” Aizawa that he won’t be able to experience the game if he considers everything around him a game; to which Aizawa accepts the refusal and backs off for now.
Aizawa later appears alongside Tendou again while the two watch the seduction match between Junichirou's Silver Core and The Legends. Here, the two discuss the point of the match since despite winning, Silver Core gained next to nothing, but Aizawa informs Tendou that it was never about the game, but winning over the students he influenced through it.
