Name: Yachiyo Tsukimi An AI administrator of the virtual world "Tsukuyomi" and a popular streamer. Opening greeting: "Yaoyoro~!" Closing greeting: "Saraba-i!" In KASSEN, she joins as a support character to fill empty slots if a team is shorthanded. She also handles power balance adjustments between teams, with her stats fluctuating based on the strength gap. In the story, she assisted Kaguya and Iro-P's team against Black Onyx (claiming, "I was on the Emperor's side last time, you know?"), resulting in higher-than-usual specs. Her outfit differs from her usual attire, changing into a "Battle Costume" consisting of a midriff-baring sleeveless top and short pants for ease of movement. Her weapon is a Japanese umbrella modeled after a jellyfish. Rather than a blunt or piercing weapon, the opened canopy rotates at high speeds to slice targets like a wheel saw; she handles distant enemies by throwing it in its active state. Naturally, it can be used as a shield when open. Furthermore, the handle serves as a blowpipe, allowing her to generate bombs using a glassblowing technique (it is unknown if she can float them like soap bubbles). She also carries a folding fan for self-defense, which she used to deflect Noi's sniping without even looking.

A girl who emerged from a seven-colored glowing gaming utility pole. Full of energy and very noisy. A live-in guest at the Sakayori household. One half of the rising duo "Kaguya & Iro-P." Opening greeting: "Kaguyahho~!" In KASSEN, she uses a bamboo hammer to fly and fire four built-in rocket launchers.

Streamer name: Iro-P Name: Iroha Sakayori In KASSEN, her main weapons are dual single-edged swords designed like a keyboard. They can be combined into a single sword or thrown as a boomerang resembling a Japanese maple seed. She can also fire piano wire from the tips for wire-action movement or to bind and attack enemies. The piano wire apparently has cutting capabilities, with a grim note stating, "I use this to take heads" (it's a wonder the Emperor survived being wrapped in it). A 17-year-old girl, excellent in both academics and athletics, who found Kaguya at the glowing gaming utility pole. One half of the rising duo "Kaguya & Iro-P." Her avatar in Tsukuyomi wears a mix of traditional Japanese clothing and a hoodie, featuring fox-like ears and a tail. Unlike her real self, she lacks the beauty mark under her left eye, having a red bindi-like ornament on her forehead instead.

Streamer name: Akira Mikado Real name: Asahi Sakayori A pro-gamer with a dominant, "ore-sama" personality. Uses a kanabo (metal club) in "KASSEN." In KASSEN, he is a short-to-mid-range attacker using a kanabo equipped with a golden carrying handle. Besides using it as a blunt weapon, he can pull out the tip to use it as a katana or an assault rifle. In the story, he thrilled fans with a flashy entrance, destroying the tiger-carriage Black Onyx arrived in with multiple quick-draw slashes. Features red hair and two horns.

Name: Rai Komazawa In KASSEN, he serves as a tank and support specialist using a Basho fan decorated with a demon mask. In the story, he set landmine traps for Kaguya while supporting Akira. The fan-shaped weapon can separate into an ogre-tile (onigawara) and a monk's staff (shakujo). He switches between "Basho Fan Mode," "Great Shield Mode" using the tile to block attacks, and "Staff Mode" where the broken tile pieces separate and are controlled according to the number of rings on the staff.

Name: Noi Komazawa Rai Komazawa's younger brother. In KASSEN, he acts as a long-range attacker using a bow. His accuracy is so high that Yachiyo praises it as "truly terrifying sniping ability." The bow limbs are bladed and can expand into a giant ring-blade. In ring-blade mode, he is depicted cutting through enemies by spinning the blade around his waist like a hula hoop while riding a tiger-bike. In the battle against Kaguya and Iro-P's team, he stalled Yachiyo with a rapid-fire slow-debuff attack that had only a 1-frame window. During the fight against the Moon People at Kaguya's graduation live, he fired a signal arrow from a watchtower to create a massive foothold, sending Akira and Rai to the front lines.
