Special: Ryou can transform into a cat. He tested the DNA fusion on himself to ensure it was safe for humans. In his feline form, he becomes "Alto," a grey cat who frequently assists Ichigo, the main character.
Mew Mew mark: Like the other girls, Ryou presumably has a DNA mark. His symbol is located on the right side of his neck and remains hidden by his collar.
Personality: Coming from a wealthy background and possessing an IQ over 180, Ryou is naturally a genius, particularly in genetics. It’s rumored he graduated from an American university. Due to this and past events, he tends to be distant, sarcastic, and rude towards most characters, except his childhood friend Akasaka-san. Beneath this exterior, he shows kindness, something Ichigo notices later in the series, especially when he encourages Lettuce, who struggles with self-confidence. Ryou seems romantically interested in Ichigo, but she does not reciprocate these feelings. He is headstrong and serious yet occasionally behaves immaturely, such as during arguments and teasing sessions with Ichigo.
