Split-release marketing? A hidden heroine?! A New Spin-off Entry in the 9-nine Series Is Coming Soon!
Palette has announced that as:9-nine- ARTEISIA, an all-ages spin-off of the 9-nine series, will be released in 2026, and its official website is now live.
All-ages releases really are a rite of passage every galgame company must go through!
Game Introduction
This is a story about a vow, centered on a certain sacred relic —
This is a world existing on a branch of possibility.
There, people developed artificial magic circuit devices — sacred relics — that allow anyone to command the miracles known as "magic." To harness this immense power, people founded the relic management organization セフィロト (the Tree of Life), and under its management, research on the sacred relics continues day after day.
Then, a girl came to セフィロト.
She had awakened magic far beyond what she could bear, overwhelmingly powerful; and a young man was stationed there as a researcher, tasked with providing her treatment.
The vow the two made gave birth to new possibilities, sprouting a fresh branch in this world.
Character Introduction
What a lavish cast (they even got Kou-kou on board)
如月 結那
CV：悠木碧
She loves joking around and is very easygoing with people, but having only moved here recently, she hasn't made any friends yet.
She lives alone in a high-end apartment incongruous with her age, doing whatever she pleases and living a free and unrestricted life.
Her grandfather heads a school of classical swordsmanship, and she grew up in the dojo, making her a formidable swordsman with the rank of "acting instructor of the Kisaragi style."
After encountering テオドール collapsed by the roadside and confiding in him the real reason she came to this city, 結那's "possibility" began to turn.
テオドール・ストラトス
CV：櫻井孝宏
A sacred relic researcher affiliated with セフィロト.
Though clumsy with words and poor at expressing his feelings, deep down he is a man of deep loyalty harboring burning passion.
He is the holder of a rare "refinement" sacred relic capable of converting his own magical power into matter.
At セフィロト he researches the relic-ization of magic, and serves as lead researcher on the research project to extract magic formulas from the human body — "アスクレピオスの杖".
クリスネイア・ストラトス
CV：石見 舞菜香
A sacred relic researcher affiliated with セフィロト.
She is テオドール's younger sister and a childhood friend of アルテシア, who is the same age.
Cheerful and never shy with strangers, she is close to ヴァシレウス as if he were her father.
She is the holder of the "thunder bow" sacred relic, capable of firing lightning arrows from a thunder bow.
At セフィロト she specializes in "transfer" research, and serves as her brother's assistant in the "アスクレピオスの杖" project.
ヴァシレウス・ラリウス
CV：大塚 芳忠
The current head of the ラリウス family with its long history, and アルテシア's uncle.
Extremely earnest with a strong sense of responsibility, he also possesses a cold side willing to sacrifice anything for his convictions.
He took in the young テオドール and クリスネイア, gave them the surname ストラトス, and taught them martial arts and refinement.
At セフィロト he serves as the person in charge of the "アスクレピオスの杖" project, providing テオドール with comprehensive support.
Interestingly, the subtitle of this work, "ARTEISIA," matches the mysterious figure "アルテシア" mentioned in the little sister's introduction — they're clearly the same person!
Looking at it this way, the true heroine may well not be 如月結那 but someone else entirely (アルテシア), and this title may just be the first installment of a split-release scheme.
STAFF
Original Art 和泉つばす
Scenario 雪仁
SD Illustrations ぺろ
和泉つばす's art keeps getting more refined, and with such a luxurious voice cast, the only remaining potential weak point is the scenario.
Judging from 雪仁's existing works, the ceiling is decent (Karehana); but the floor is also quite low (Nekopara). Add the all-ages buff on top, so it's best not to set expectations too high for the scenario — though perhaps the writer will suddenly surprise everyone.
This title was leaked last year, when it was expected to release in winter this year, but now it has become 2026 — isn't that just another delay~ Still, after being held back this long, it might release quite soon, so interested friends may want to keep an eye on it.
