Radio club from TMHK

A ghost who was formerly human and is considered the Seventh School of the Kamome Mystery Academy. Height: about 150 centimeters.
In his human form, he wore the old Kamome Academy summer uniform: a white Western-style shirt with short sleeves, black pants, a belt, and white shoes.
He wears a black school uniform: a black gakuran with gold buttons, a white collar, and red hems, under which is a white, long-sleeved Western-style shirt, black shoes, and red socks. He also wears a black hat with a white lining, a gold emblem, and red strings.
Sometimes appears wearing a long, flowing black cape with a golden-red collar and a red underside.
On his left cheek, he wears a white seal with the kanji "封" (seal) written in red. He appears to be a playful and somewhat sadistic ghost who approaches his duties with a certain frivolity. He treats most people with familiarity, behaves in a cheeky and relaxed manner, and often jokes and teases.
Despite her apparent dismissiveness, she values ​​and cares for her friends greatly. She always comes to their aid and worries when they are in danger. She feels guilty if she deeply offends them and sincerely apologizes. Hakujodai are two ghostly, translucent spheres (one with a turquoise core, the other with a red core) controlled by Hanako. She uses them as weapons against other spirits, for reconnaissance, and for surveillance. The red hakujodai allows teleportation, while the turquoise one creates a cloak that enhances Hanako's abilities and makes her immune to lightning generated by anti-spirit items.
Duty: To watch over other supernatural beings in the school and maintain balance between the living world and the spirit world.
He can put a person to sleep by touching their forehead with two fingers. His primary motivation is to atone for the sin of killing his own twin brother, Tsukasa. He serves as the Seventh Secret, maintaining order between the worlds of the living and the spirit world, believing this will help atone for his guilt.

Capabilities
Spirit and Ghost Vision: Nene is able to see supernatural beings (including Hanako) without any connection to them. The reason for this differs from the standard explanations in the manga world.
Fish Transformation: After Nene swallowed one of the Marriage Beads, she began to transform into a fish when in contact with water:
when hands get wet, pink scales appear on the skin (disappear after drying);
in water it completely transforms into a miniature fish with light pink scales, turquoise fins and tail, small horns and a brooch with a ribbon;
Outside of water, he maintains his human form thanks to his contract with Hanako.
Other conditions:
Hanako's obsession: appearance remains almost unchanged, but eyes become sharper and acquire an amber tint;
Mocca form: appears in a dream, leaving only the horn-shaped hairpins and a brooch with a bow.

Androgynous—many note his "girlish" appearance. A slender and relatively tall middle-school-aged ghost with pink hair and eyes. He has a mole under his left eye, medium-length hair with bangs covering his right eye, and his hair is usually pulled back into a small ponytail held in place with bobby pins. He wears predominantly pink clothing.
He was a student at Kamome Academy High School and a member of the photography club. He died in a car accident in winter. He was friends with Ko Minamoto until his death.
Tsukasa Yugi forced him to absorb the heart of the former Third School Mystery, resulting in Mitsuba becoming its representative—the representative of the Third School Mystery, the Hell of Mirrors. Personality: Self-assured, foul-mouthed, and overly confident in himself, especially his appearance. He often boasts about how cute he is. He tends to call people rude names and isn't afraid to insult others.

Personality: Reckless, unfriendly. His motives are questionable; it seems he helps Tsukasa and Sakura simply because he's in love with Sakura. He's hopelessly in love with Sakura, obsessed with her, and continues to fall in love with and pursue her despite her lack of affection.

He controls two hakujodai (koku-jodai), similar to Hanako's, but black instead of white, with pink and blue circular markings, respectively. In the past, Amane Yugi killed Tsukasa, and this became his greatest sin, binding him to the school. Tsukasa returned as a sinister spirit and became the story's main antagonist. He symbolizes the connection between the worlds of the living and the dead, as well as the possibility of healing through friendship and love. Unlike Hanako, who grants wishes to the living, Tsukasa grants wishes to the dead. He believes that rules and order between supernatural beings and humans are unnecessary, and believes that supernatural beings should be able to act as they wish. He doesn't place much emphasis on the topic of his own murder, often mentioning it without hesitation. As a ghost, he appears cheerful and frivolous, but easily switches to a disturbing, cruel side: he acts impulsively, capable of killing simply because he finds it funny. A short boy with tangled, tousled dark brown hair and large amber eyes.
Almost an exact copy of Hanako (the older twin brother), except for the constricted pupils and two protruding fangs.
In his first appearance, he wears a gakuran uniform and a hat similar to Hanako's, but later changes into a shosei-style uniform: a white Western shirt with a black kimono, a grey hakama, black shoes, red ankle socks, and a hat similar to Hanako's.
On his right cheek is a black seal with the character 封 (seal), indicating his status as a yorishiro (like Sumire) and likely a yorishiro of Amane. Birthday: November 25th. Age at death: 13; as a ghost: over 50 years old.

Green hair styled in an asymmetrical bob with very short bangs. Two strands frame her face in front of her ears, and two longer strands reach her chest. Two braids run from the crown of her head to her ears. Green eyes with yellow highlights. She has prominent eyelashes, and her eyes are always half-closed, giving her a sleepy or disinterested appearance. She usually keeps to herself and is not prone to showing emotion. Her facial expression is usually impassive, and she rarely changes it.
Linked to the supernatural through a contract with Tsukasa, she can see other supernatural beings.
She dislikes Tsukasa's actions, but is forced to obey him. However, she enjoys Nene's company and wants to be friends with her. Her favorite food is rakugan. She is bothered by Natsuhiko's actions, which irritates her. Her preferred type of guy is Fukuzawa Yukichi. She is a member of the school radio club. Together with Natsuhiko, Hyuga shares new rumors about ghosts on the radio.
She made a contract with Tsukasa and became bound to him, similar to how Nene became bound to Hanako.
Despite being a hundred-year-old ghost, Sakura can disguise herself in the human world, posing as an 18-year-old third-year student at Kamome Academy.
