Honoka is friendly and kind towards others. She loves her big brother very much and enjoys watching his training and is worried over how hard he has it at Ryozanpaku. She enjoys hanging around Natsu and thinks of him as another big brother (as Natsu thinks of her as his deceased little sister).
She has a bit of a mischievous side, often following her brother to the dojo that he trains at, despite him telling her not to, and trying to make him come home. She even broke into his room and tends to annoy him because she likes being with him. She seems to be a bit jealous Miu, who she calls "Big Boobs" due to her figure, believing her to be the only reason Kenichi stays at the dojo, which isn't completely true as he just wants to become stronger to protect his loved ones. She tends to lose her temper when upset and leaves in crying fits such as when Kenichi refused to go home. She tends to be impressed by her father when he tries to do something overdramatic, often believing it to be the right thing to do, especially with anything pertaning to Kenichi.
Honoka enjoys hanging around Shigure and Apachai, whom she plays board games with. She also often teaches them minor things they are unaware how to do such as how to make tea. She knows some level of martial art moves due to her watching her brother train and having her mother teach her some techniques.
Honoka has a similar hairstyle to that of her brother Kenichi, being short brown hair except she has no fringe in the front. She typically wears striped shirts or her school uniform or a dress. Miu describes her as being very cute for her age.
