白浜ほのか
from History's Strongest Disciple Kenichi
Honoka Shirahama is Kenichi's younger sister, who cares for her brother greatly, often competing with Miu for his attention. The second time she visits the Ryōzanpaku dojo, she shows Shigure and Apachai 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.

History's Strongest Disciple Kenichi
Shirahama "weak legs" Kenichi is a typical high school student with typical problems: he's frequently bullied and tends to run away in the face of his enemies. Things change when Kenichi meets Furinji Miu, whose grandfather runs a dojo; and not knowing what he's getting himself into, he signs up to become a disciple. As Kenichi's life-threatening training continues and he becomes more and more powerful, he inadvertently becomes the target of the deadly gang called Ragnarok. With mental and physical challenges ahead, can Kenichi survive his encounters with Ragnarok, or will the masters of his dojo get to him first?
