Mitsuhiko Azuma is an elderly man who appears as a supporting character in the Too Cute Crisis series. He is sixty-two years old, with short gray hair and brown eyes. He is the grandfather of Kasumi Yanagi and also of Hanazumi and Sasara Azuma, with Sasara living together with him. Azuma has a deep fondness for hamsters and has kept many of them over the years; at one point he is caring for his seventeenth hamster, a Djungarian hamster named Mitsurou. His enthusiasm for his pets is strong, and he often holds differing opinions from Sasara when it comes to the best way to care for animals. In the story, his role revolves around his family connections and his hobby, contributing to the everyday-life and pet-focused moments of the series. His caring but occasionally stubborn attitude toward his hamsters defines much of his personality and interaction with those around him.
