Michibiki Honoka♀

Honoka is amiable, full of curiosity, and always ready to play a prank on someone. Everyone gets along with her. She’s the protagonist’s childhood friend and they were recently reunited after not having seen each other for a year. Her pranks can be of a very provocative nature and the protagonist finds it difficult not to get carried along. Her family owns a workshop that manufactures a variety of rocket parts. She’s extremely talented in her father’s line of work, which requires high dexterity and skill, but does nothing productive with her abilities.
