Youmu Konpaku is a half-phantom gardener and swordsman living in Hakugyokurou, serving Yuyuko Saigyouji. She is serious and hardworking but airheaded and easily teased, with a habit of tuning out difficult conversations. Despite being half-phantom, she is ironically terrified of ghosts. In battle, she dual-wields the Roukanken and Hakurouken, capable of cutting through enemies, spirits, bullets, and even worries; her high-speed slashes while teleporting are too fast for even Aya to track. The Hakurouken is a special blade that severs hesitation and allows spirits to pass on. Usually polite and well-mannered, she turns somewhat sadistic when she draws her sword. She is characterized by silver bobbed hair, a black ribbon, and blue-green clothing, and her phantom half can be used for attacks. She lives in a share house with the other members. She feels awkward around Buriko—or rather, she hates her, or just can't deal with her...

Satori Komeiji is the mistress of the Palace of the Earth Spirits and a Satori, a yokai capable of reading minds. Due to her mind-reading abilities, she is hated by many yokai and tends to be a shut-in, but she is very well-liked by animals and lives surrounded by pets. She has deep affection for her sister Koishi and her pets, possessing a motherly and kind nature. Her demeanor is quiet and soft, but she is overwhelmingly confident with a self-evaluation of 11/10 and strong mental fortitude. In conversation, she immediately guesses the other person's thoughts, making communication difficult and exhausting even for Reimu. While she reads surface thoughts, her spell card "Recollection" can trigger trauma and recreate past danmaku; in battle, she can copy final-boss-level techniques. She is a doting sister who will go to the surface to search for Koishi, and the gap between her quiet loneliness and her high self-confidence is her charm. She hates Buriko. She finds her difficult. Since she can see everything in Buriko's heart, she tries not to look as much as possible.

Fujiwara no Mokou is an immortal Hourai human living in the Bamboo Forest of Lost. Since her body regenerates from her soul even if she dies, she is truly immortal, fighting with fire sorcery and phoenix-like danmaku. She is strong-willed, has a delinquent-like bluntness, but is kind and caring at heart. She is compassionate, helping humans who get lost and deeply trusting Keine. Due to her immortality, she is self-deprecating and neglectful of her health, but she enjoys listening to people talk. Her rival is Kaguya Houraisan; since their reunion, they are in a "frenemy" state where they kill each other constantly. After long isolation, her relationships with Kaguya, Keine, Sumireko, and Mamizou have become her emotional support. She has long white hair, red eyes, and wears monpe trousers with talismans. She is known for her bold fighting style, attacking while wreathed in flames and self-harming. She hates Buriko. She avoids her blatantly.

Dabi is a member of the League of Villains, a cold-blooded villain who uses the Quirk Cremation (Blueflame). He is cynical, elusive, and has no hesitation in committing murder. Because his body is not suited for his Quirk, he burns his own flesh with his flames, leaving his body covered in keloid scars and surgical staples. His true identity is Toya Todoroki, the eldest son of the Todoroki family. As a child, he was the focus of his father Endeavor's expectations, but he was cast aside when his self-harming constitution was discovered. He felt completely replaced by Shoto's birth, leading to deep-seated hatred. Though thought to have died in an accident during training, he survived after being picked up by All For One in a near-death state. Driven solely by revenge, he operates as Dabi, fueled by his grudge against his family. He maintains a fierce rivalry with Shoto, though a slight emotional connection as brothers is eventually depicted. Dabi is a tragic character who became a symbol of obsession with his father and self-destruction, often called the "Death-Flame of a Paranoiac." He hates Buriko.

Weight: Around 55kg–62kg (a lean, toned build that looks good in kimono and hakama). Speech: Uses "-da," "-da na," "-ro." First person: I (Ore), rarely "sessha."

Satsuki Matari is the protagonist of "The Man Despised as the Most Incompetent in School is Dangerous When He Snaps." True to the Matari family, he is a person who doesn't hesitate to sacrifice himself for his loved ones. He cares deeply for Koishi, Shiro, Mui, San, Shiki, and others. He has two types of abilities. First is Wrath. He converts anger into energy, using it for attack, defense, fire, and physical enhancement. He is especially prone to losing control when a loved one is hurt. Second is his true essence, Greed. A dangerous ability that converts desire into power and allows him to steal the abilities of those he kills. After losing control in his childhood and taking his older brother's arm, and killing many ability users including his father, San Matari, he now hosts numerous abilities. When Greed is active, his hair turns black and his speech becomes childish, indicating that his true self remains a "child."

Marx is the final boss of the "Milky Way Wishes" segment in Kirby Super Star. Appearing as a jester, he pretended to help Kirby while being the one who caused the sun and moon to fight. He manipulated the plan to have the galactic comet Nova grant a wish, betraying Kirby by declaring, "I'm gonna rule Popstar!" and revealing his true form. In battle, he is a formidable foe who uses a variety of attacks like cutters, ice, seeds, lasers, and black holes, while confusing the player with teleportation. After being defeated, he crashes into Nova and is destroyed, but in USDX, he returns as Marx Soul in a maddened state with even more vicious attacks. In later titles, he became playable in games like Star Allies, fighting by switching between his jester and true forms. He also appeared as a boss in Super Smash Bros. Ultimate, surprising players with an even creepier presentation than the original. Does he hate Buriko? He has no interest.
