Kaito Shinonome

Kaito has a strong sense of justice and hates corrupt things, but tends to pick fights and prefers to go about his business alone as he doesn't like to rely on others. Kaito cares deeply for his sister, worrying for her all the time, but they often misunderstand each other because Kaito is clumsy at expressing himself.

Kaito's obsession with protecting Miu becomes even stronger whilst in the alternate World, leading him to become violent and hurt those around him. This obsession also annoys Miu and causes her to rebel against him. Dracmon helps Kaito calm down and think carefully before he acts.

If Takuma asks Kaito why he likes Miu so much, he will go on a long tangent in which he states he loves her physical appearance due to her being so cute and small, loves her cute eyes and the way she looks at him, the way she eats with her small mouth, and how slender her arms are with that making him wanna protect her. This freaks Takuma out, with him coming to the conclusion that his affection for his sister is incestual —though Kaito angrily relents that isn't the case and claims his affection for her is normal for a brother.
