Hanako Ōmuro (大室 花子 Ōmuro Hanako ) is a supporting character in the anime, as well as one of the main characters in the spin-off manga series Ōmuro-ke. She is Sakurako and Nadeshiko's younger sister, and an 8-year-old elementary school student.
Much like Nadeshiko, Hanako is showcased as having quite a mature personality, being able to handle most things on her own, and is also showed to be quite a prodigy in most things she studies at school. She also appears as having quick thinking over situations, as displayed when she ended up being the one helping Akari out after a series of small incident, some time during Season 3.
