Shirogane, Ryou

Weight: N/A

Special: Ryou has the ability to transform into a cat. This is because he wanted to make sure the DNA fusion would be safe in humans, so he tested it on himself. Hence, in cat form, he takes on a new personality and becomes "Alto", the grey feline who's always helping out Ichigo (the main character).

Mew Mew mark: Ryou assumably has a DNA mark like the rest of the girls. His symbol is located on the right side of his neck and is always hidden by his collar.

Personality: Ryou comes from a wealthy family and has been stated to have an IQ surpassing 180, making him a natural genius, especially when it comes to genetics. It has also been rumored that he graduated from an American University. Because of this, and events in his past, he has a removed, sarcastic, and rude nature towards most of the cast, apart for his childhood friend, Akasaka-san. Despite this, he seems to be a kind person underneath, something that Ichigo catches on to later in the series, probably most obvious when he is trying to encourage Lettuce who has little self-confidence. He seems to have a romantic interest in the main character, Ichigo, but, these feelings are not returned. Ryou is headstrong and serious, but has moments where he will behave immaturely, such as his arguing with and teasing Ichigo.
