Hō Honoka is a minor character from the science fiction anime Knights of Sidonia. She is one of the Honoka sisters, a group of numerous identical young women who are clones engineered specifically to serve as pilots for the Garde mecha units that defend the generation ship Sidonia from the alien Gauna. Like her sisters, Hō Honoka was created through accelerated growth processes, allowing her to reach physical maturity and be deployed in combat at the chronological age of approximately five years old. She possesses enhanced physical strength and agility as a result of her genetic design and conditioning. Her appearance is uniform with her siblings, featuring light pink hair styled in a hime cut and brown eyes, reflecting the standardized cloning methodology used to mass-produce pilots. No specific details about her individual personality are provided, though her actions and role are defined entirely by her function as a frontline combatant.

Hō Honoka is designated as the pilot of unit TS-205, which is later re-designated as unit 705. Her primary purpose and motivation are simply to defend Sidonia from Gauna attacks, a duty for which she and her sisters were created. She is part of a larger cohort of Honoka clones that includes sisters such as En, Ren, Ro, Yō, and Shō, among many others. Her key relationships are almost exclusively with these fellow clones, as they operate and live together as a unit, often seen basking under artificial lights to sustain themselves through photosynthesis rather than consuming traditional food.

Hō Honoka is notable in the story for being the first of the Honoka sisters to be killed in action. She meets her end during a battle against a powerful Gauna known as the Crimson Hawk Moth, also referred to as Benisuzume. Her death takes place during an engagement in the third volume of the original manga, witnessed by her sister Ren Honoka, and prompts a rescue attempt by the series' protagonist, Nagate Tanikaze. This event underscores the brutal and expendable nature of the clone pilots' existence, as their high casualty rates are accepted as a necessary measure to maintain the ship's defensive capabilities against the relentless Gauna threat. In terms of development, Hō Honoka's arc is tragically brief, beginning and ending with her deployment and subsequent death in combat. Her notable abilities are those common to all Honoka sisters, including her physical enhancements and her proficiency in piloting a Garde, which she utilizes in support of the Sidonia's defense forces.
