Hana

Hana is an anatomical model split down the middle: exposed muscle on her right, a covered skin half on her left. The skin side shows hair pulled back and a shut left eye. She has no limbs at all, unlike Taro, so a round base fixed to her lower torso is what keeps her standing. Once she settles into the Ayase residence, a beanie along with a shirt are added to keep her covered.

Hana shares a deeply affectionate bond with her partner Taro. Lively and responsive toward him, she falls completely silent in front of everyone else, perhaps out of shyness or because, as fellow anatomical models, the two can only speak to each other.

Hana grew close to a fellow anatomical model, Taro, back at Kami High, but the pair were split apart after she was discarded as an outdated model. Taro later finds her in a junkyard, hurrying to reunite, and his frantic dash draws Momo, Jiji, and Okarun, who have been trailing him. Hana urges Taro to let her go, having accepted her fate, yet his devotion moves her. Momo invites her to live at the Ayase residence so the couple can stay together, and the next morning Hana waits with Momo for Taro, who arrives late after a truck runs him over.

During the Evil Eye Arc she sits quietly through the family dinner, then resurfaces as Okarun battles the Evil Eye, carried about by Momo. When the Evil Eye strips off his underwear, breaking Okarun's deal, Hana, Momo, and Aira are spun around to look away. With Seiko too worn out to face their wrecked home, Hana joins Turbo Granny, Momo, and Seiko to rest at a bathhouse. Momo carries her home again just as an alien appears watching them, and after Okarun and Aira quietly summon Mantis Shrimp, who enlists his friend Ludris to put the house back together. Hana is glimpsed one final time within the half-finished Ayase residence.
