One of the Demons on the Warriors of Hope's Demon Kill List being hunted down By Kotoko. 

Kanon Acts like a sterotypical model who is stuck in the 90s, is rather lustful, perverted, and appears to be rather self conscious about herself, dressing up really flashy and looking pretty to make herself feel better. Kanon is Leon's younger cousin by two years. The two are implied to have a sibling-like bond since childhood,she is very devoted to Leon, to the point of obsession. She loves him more than anything, saying that he is her world. When she finds out that Leon has died due to the members of the Future Foundation, she swears to take revenge. Even after his death, she loves him, and whispers his name in her sleep.  Kanon was chosen as Leon's hostage during the School Life of Mutual Killing, meaning that she was extremely important to him, more than anyone else in the world.   

After saving Hagkure from a monokuma attack she decides to travel with him in an attempt to escape the city.
