Honoka Shirahama

First appearance: Battle 2

Martial Arts: None

Shirahama Honoka is Kenichi's younger sister, who cares for her brother greatly, often competing with Miu for his attention. The second time she visits the Ryozanpaku dojo, she shows Apachai and Shigure 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. 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 wheres striped shirts or her school uniform or dresses. Miu describes her as being very cute for her age, but in reality, she is much younger looking than her age. 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 over their. She enjoys hanging around Tanimoto Natsu and thinks of him as another big brother (as Tanimoto 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 and believing he's going through cruel training she tried to get him to come home. She even broke into his room and tends to annoy him because she likes being with him.
