Chika Daimon

大門知香

Masaru's younger sister who's nowhere near as reckless as her brother. She has no official Digimon partner, but does befriend a Biyomon who eventually causes Mercurimon to come into the real world to bring Biyomon back. She argues a good deal with her brother, but they otherwise get along well. Chika also seems to have a crush on Touma.
