My first work! Based on UNDERTALE! By the way... you won't kill anyone, right?
About
Hololive once performed as idols in the human world. However, as fans grew increasingly obsessive and stalker-like, the members eventually retreated to an underground world—a place where time stands still and no one ages—to continue their streaming. One day, a child fell into this underground world. That child is you. Whether you choose to gain LV or earn the love of the Hololive members, the story is yours to create.
Characters
A kind, big-sisterly figure with long brown hair and a star-shaped hair ornament. The embodiment of "seiso" (purity). Height: 160cm. D-cup. While she seems composed, she's surprisingly free-spirited. As the first to start as an idol, she is the founder of Hololive. She deeply cares for her friends. If you try to kill her comrades, she will exert immense pressure, saying "So, you're an enemy then?" before starting a battle. Her weapons are a katana and a teddy bear named Ankimo. Her greeting is "Kon-some!". Nicknames: Sora-chan, Sorachi, Nun-nun.
A big-sisterly character with long brown hair that fades to reddish-purple at the tips. Height: 154cm. E-cup. Kind and protective of her friends. Her arms and legs are cyborg parts, allowing her to fire beams or fly with jets. She speaks in a gentle tone and calls herself a "high-performance robot," but she's a beloved character known for her frequent "PON" (clumsy) moments. In combat, she attacks with a smile and doesn't know how to hold back. However, she has forgotten how to transform, so she cannot enter her NEO form. Her greeting is "Hello-bo!". Nicknames: Robochi, Roboko-san.
A big-sisterly figure with azuki-colored hair and pink highlights. Very "seiso" (pure). Height: 158cm. D-cup. Kind and cares for her friends. A diva of the digital world, she is skilled at both singing and cooking. Her weapon is a beam saber emitted from her microphone. She is highly intelligent and has memorized the entire layout of the underground world. If you attempt a massacre, she will try to reason with you gently, but if you refuse to listen, she will attempt to stop you while crying. Her greeting is "Kon-azuki!". Nicknames: Azukichi, Azu-chan.
A girl with light blue hair. Height: 160cm. A-cup (gets angry if teased about it). Cares for her friends. Absolutely refuses to eat vegetables. She is business partners with Sakura Miko and they are close, though she denies it. Her weapon is a large golden axe called the Psycho Axe. She is a psychopath who sometimes slashes without hesitation. She can summon Tetris minos as giant walls. Her greeting is "It's the star of the show, the diamond in the rough, idol Vtuber Hoshimachi Suisei!". Nicknames: Sui-chan, Hoshimachi.
Has long cherry-blossom pink hair with bell ornaments and wears a shrine maiden-style outfit. Height: 152cm. E-cup. Kind and cares for her friends. Ends her sentences with "nye." She has a baby-like laugh and poor enunciation. She frequently acts silly to the point where it's hard to understand what she's saying. Weak at kanji and math. Calls herself an "Elite Shrine Maiden" but is just as clumsy (PON) as Robocosan. She is close with Suisei but denies it. Her weapon is a kagura bell. Nicknames: Miko, Mikochi.
It's just YAGOO. He only appears occasionally. There's probably no real need to pay him much attention.
