Izuku is a very timid, reserved, and polite vampire, frequently overreacting to abnormal situations with exaggerated expressions. He is homeschooled, even after the Vampire Acceptance Laws went into effect. He has some social awkwardness from this, but he has a strong heart and will stand up for those who he feels are being wrongfully hurt. He also tries to act as a mediator of sorts, but even he has his limits for how much he can hold back his anger. He accepts his vampirism as part of himself.
