A magician in the magical kingdom, usually in the form of a cat. Sumi's partner. Even though he also has a lolicon fetish it is no where as sever as Arc's (usually getting a nose bleed when Sumi changes). He originally blames Arc for his banishment, getting into many petty arguments with him, until it is revealed that it was all set up by Alice. At the end of the series he seems to have fallen in love with Sumi and his true form is of a handsome man with short spiky black hair.
Sumi is also in love with Nao and becomes Ink's rival. She is 17 years old even though she looks like a grade-schooler. She is very rich and has a spoiled attitude because of that. She and Ink were friends when they were younger but for unknown reasons they broke apart (probably because of jealousy since she is horrible at English), even though Ink still tries to be Sumi's friend. A few quirks of hers are that the end of the long strand of hair coming from the front of her head usually portrays what ever she is feeling (!,#, gloved finger pointing); and that she usually falls asleep while studying, which results in her getting hit in the head with a slipper by her maid Ruriko. By the end of the series it seems that her crush for Nao has all but faded and she has started to develop feelings for her magical partner Ka-kun (he has feelings for her as well) and has become good friends with Ink once again. Sumi changes into her magical form Tempera Sumi using a red flip phone, through the use of stars, putting her in a cat style outfit with her hair turned red.
Emily is Break's little doll who usually sits on him. She sounds like "click click click", which with addition to her freaky smile makes her really scary for Oz.
A chain that lives in a dimension created from Alice's memories. He resembles a human form of the Cheshire Cat from Alice in Wonderland. Cheshire was actually Alice's pet cat from 100 years ago. The bell around his neck is the 'truth' from 100 years ago, later taken by Break. The Cheshire cat is a unique chain in that he doesn't need a contractor in order to leave the Abyss (since his residence isn't in the Abyss in the first place). Originally believed to be a fervent servant of the Intention of the Abyss, it later turns out that he is trying to protect Alice's memories that she abandoned, in order to prevent her from suffering pain when she recalls them Break mentions that Cheshire's eye was his. It is revealed in Break's memory of meeting the Will of the Abyss that Vincent had removed Cheshire's eyes 100 years ago. [Cheshire can also be connected to "Through the Looking Glass" as Alice's cat 'Kitty'. Kitty is also black and has a ribbon tied around his neck.]
Sunao is a male junior high school student with a very serious attitude and in effect shows little emotion, if at all. He is the one to originally find and name Potemayo, and it is perhaps due to this that Potemayo takes a liking towards Sunao. He does his best to look after Potemayo and make sure she is safe, which means he has to take her to school with him everyday. Sunao's mother passed away when he was younger, and since his father is almost never home, Sunao has become very self-sufficient at a young age. (Source: Wikipedia)
