Honoka Shirahama (白浜 ほのか Shirahama Honoka) is the younger sister of Kenichi Shirahama whom she cares for greatly that she often competes with Miu Fūrinji for his attention. The second time she visits the Ryōzanpaku dojo, she shows Shigure Kōsaka and Apachai Hopachai how to properly make tea, which impresses them. Honoka soon becomes good friends with the two masters and consequently visits the dojo regularly to play with them.
Physical Appearance
Honoka is a very cute girl for her age group (as described by Miu Fūrinji) has the expect same hairstyle as her big brother Kenichi Shirahama has but her hair was shorter brown hair except she has no fringe in the front and has brown eyes.
She typically wore striped shirts or her school uniform or a skirt.
Personality
Honoka is a caring and friendly girl towards others who loves Kenichi Shirahama very much that she enjoys watching his training and she is worried over how hard he has it at Ryōzanpaku. She enjoyed hanging around Natsu Tanimoto and thinks of him as another big brother (as Natsu even thinks of her as his deceased little sister).
She has a bit of a little sister complex, often following her big brother to the dojo that he trains at, despite him telling her not to, and trying to make him come back home. She even broke into his room and tends to annoy him because she likes being with him. She seems to be a bit quite jealous towards Miu Fūrinji, who she calls "Big Boobs" due to her body shape, 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 bad temper when she is upset and leaves in crying fits such as when her big brother Kenichi refused to come back home. She even tends to be impressed by her father when he tries to do something over dramatic, often believing it to be the right thing to do, especially with anything pertaining to Kenichi.
Honoka enjoys hanging around Shigure Kōsaka and Apachai Hopachai, whom she plays board games with them. She also often teaches them a few minor things such as they were unaware of how to do such as how to make tea. Honoka even knows some level of martial art moves due to her watching her big brother train and having her mother teach her some of her techniques.
