Ryo Kurokiba is Alice Nakiri's aide. For the most part, Ryo is normally very slow, lazy, and gloomy. His general demeanor lacks any sort of interest in what is going on around him, but he remains attentive to the needs of Alice. He is not shy to speak his own mind or criticize Alice in this form but generally will only speak when necessary if he is with anyone but Alice. His speech is formal and simple, but slow. However, Ryo has a much more passionate personality that only emerges once he wears his signature bandana or any sort of tight-fitting headgear. This new demeanor is much bolder, wilder, and untamed, akin to a wild beast, fittingly called his "Berserk Mode". His speech is also much more aggressive as he has no qualms as to whom he talks to, even having violent outbursts in an instant. However, if someone were to remove his headband, he will instantly revert to his usual gloomy personality even in mid-sentence. Ryo considers all kitchens to be a battlefield with the food a chef makes as a representation of their power. He thus loathes bonds between chefs as he believes that such soft feelings weaken a chef's true capabilities.
