K anon is an associate of Nodoka's in the Hungry Butterfly Maid Cafe. She and her parents moved to Kanzakai with her parents due to living near the coast of Fukushima. While her parents constantly relocated around the prefecture, they eventually gain the brain power to realize it's not a good idea to live in such risky places of the Tohoku region. She is fairly talented at tennis, and is pursuing to become a tennis star, constantly competing in tournaments at her college. She also dual-majors in business, because it'll allegedly make her look better in comparison to sports stars with no experience in said field. She works at the cafe for supposedly nothing more but work experience, but she secretly knows she joined to watch the maid dresses flow with every step. She is also the only worker to wear a butler outfit, though she is anal about the quality of the maid dresses her co-workers wear. She tends to flatten out wrinkles, offer to wash them after work, and fixes collars and straps spontaneously if something seems off. Despite her abnormal situation, she personally finds it normal, taking a liking to her personal slice of life with her family and eventually their Voids. She doesn't talk much, which can make her seem dry and uncaring of her surroundings, but she has a strong work ethic and a sense of care and common courtesy.

Her mother Miku and her father Akihiko (usually just called Aki) are obsessed with the paranormal and several psuedosciences, though it is all thankfully harmless stuff and not dangerous rhetorics. They are most concerned with ufology and alien sightings, believing that aliens are making their way here in these unidentifable spacecrafts to collect human DNA and create human clones. They have dumped way too much money into organizations for UFO research than I really want to say. The two of them were extremely renowned people before their sudden switch in occupation, as Miku was a mangaka for a widely popular manga and Akihiko was a airline pilot before their retirement. Aki hosts Takanohana, Miku hosts Yua, and Kanon hosts Midosuji.

Kanon was not always stoic, and in her teenage years she was convinced that she was a fallen angel that turned into a half-demon meant to observe humans to quell her powers. Once her uncontrollable powers were calmed, she could go back to the Holy World and become an angel again. So she thought. She was blunt, unnecessarily mean to others because of her demonic powers taking over, and mischievous. She was arguably just as wacky as her parents, but grew out her phase once her parent's antics ramped up, realizing that it's all very silly, leaving behind her chunni syndrome. Sometimes her college friends bring it up and she gets flustered. Now, she's just a cool, casual gal who is a bit critical about her generation and their form of entertainment, and her friends and family are enraptured by the way she holds herself. Her family misses the crazy phase though.
