Friendly yet inept, Io Azuma is a distant cousin of Suzuna and is good friends with Tomomi. He was originally chosen to be a suitor for Suzuna, but much to her disappointment, he matured somewhat effeminate instead of into the charming gentleman she was expecting. A devout otaku, Io frequently spends most of his leisure in the house library reading manga; playfully extending his obsession to Suzuna who, much to her chagrin, he tends to address with the Japanese honorific title Chan. He and Koichi have no sexual contact in the anime, unlike in the original game.
