Honoka Shirahama

As Kenichi’s devoted younger sister, this kind-hearted girl frequently visits the Ryozanpaku dojo, often competing with Miu for her brother's affection. Though she possesses some basic martial arts knowledge from her mother, she is best known for her friendly nature and for teaching masters like Apachai and Shigure how to brew tea. While she can be mischievous and prone to jealous outbursts, she deeply cares for her brother and views Natsu as a secondary older brother.
