About
"There are things better left unknown" — The hidden masterpiece by ImCyan, creator of "Tsugunohi," finally arrives on Steam
A hidden paranormal detective mystery is revived on Steam. Experience the diverse presentation and gameplay that laid the foundation for the evolution of "Tsugunohi" today.
A full-scale drama-style horror adventure game where the protagonists, paranormal detective Yumemi Teru and his sister Yumemi Luna, who possess the special ability "Dream Link" to enter the dream worlds created by ghosts after death, solve spiritual cases occurring in the city.
Inheriting the will of their late mother, Yumemi Mimiko, the siblings dive into the dream worlds to save those who "know too much."
This is a full-fledged story-driven ADV by ImCyan, author of "Tsugunohi," originally published on the game site "Game Magazine" (which also featured "Angels of Death" and "Noel the Mortal Fate") from fall 2016 to summer 2018. Unlike "Tsugunohi," this work features exploration, mini-games, and various gameplay elements.
This package includes all episodes released at that time (Episodes 1–9; the 2018 special "The Case of the Mermaid" is not included). It serves as a perfect introduction to ImCyan's unique world for both long-time and new fans of "Tsugunohi."
While using the familiar side-scrolling system of "Tsugunohi," this game incorporates unique story elements, settings, and game systems.
◆ Fascinating Ability Settings
Teru's "Dream Link": The ability to enter the dream worlds created by spirits
Luna's "Curse of the Red Thread": Supports returning from dreams to reality
◆ A blend of horror and comedy
The protagonist works as a host in Shinjuku in a surprising turn
Deep human drama themed on "Shikiyoku(lust)"
A unique balance of humor and horror
◆ Authentic Investigation and Deduction Elements
Gathering information in various places
Gradually revealing complex mysteries
A serialized mystery story that deepens over time
The deep bond between Teru and Luna, the mystery behind their mother’s death four years ago, and the truth of incidents involving the "Curse of the Shikiyoku" and "SHIKIYOKU".
The story starts in a high school horror setting and unfolds across diverse locations including Shinjuku's host district, Akihabara, and forbidden lands, evolving into a serious, heavy narrative.
The responsible paranormal detective Teru (CV: 横割れスプーン)
The innocent yet jealous Luna (CV: 真宮ひな)
Their mysterious late mother, Mimiko (CV: 西野五月)
Various unique supporting characters
9 episodes in total
Around 1 hour of playtime per episode
Over 10 hours of total playtime
From Episode 1 "The Case of the Missing High School Girl" to Episode 9 "The Case of Mimiko Yumemi's Disappearance"
Enjoy the grand narrative experience unique to serialized works, with different settings and incidents unfolding in each episode. (Note: The series is currently unfinished.)
※ Please read before purchasing (About future updates) ※
This package includes Episodes 1–9, originally released up to 2018. It does not include the special episode "The Case of the Mermaid" or any content from Episode 10 onward. As such, the series remains unfinished.
The developer, ImCyan, has expressed a strong intention to resume development and complete the story. Future episodes will be released as Steam DLC once completed (release date and pricing are currently undecided).
We sincerely apologize for the long wait and deeply appreciate your patience.
Please look forward to the continuation of the series at your own pace.
Any updates will be shared through Steam News or the official X account.

死期欲第九话 梦魅美美子失踪事件 未完待续
玩得想睡觉
我的年度游戏
好玩露娜可爱

Arguably Imcyan's magnum opus. An episodic Tsugunohi spin-off with genuine character & plot progression (owing to the cast being allowed to live longer than a single episode). Writing chops on display here are impressive; was genuinely surprised by how effectively this managed to strike the proper chords (whether funny, dramatic, or spooky). Combine this with each episode having its own distinct identity (& occasional unique mechanics) & I'd have no choice but to strongly recommend this for anybody in the mood for a unique adventure. That said, as the store page states, this release IS unfinished and Episode 9 leaves off on something of a gigantic cliffhanger. Something to keep in mind.
能想到骨科然后牵红线变成一个线电话不得不说作者你真的是个天才……总之也是本人嗑骨科启蒙,忽然上steam了,是小时候爱吃的味道。恐怖游戏很多,但能让你一直开怀笑的搞笑恐怖游戏很少,就算全是跳杀又如何呢。毕竟,这基本就是一个建立在跳杀之上的游戏…众(?)所周知,玩这款游戏能起到降低智力的效果,而降低智力又起到一个傻乐的效果,所以这款游戏可以当电子抗抑郁药使用。(果然只有日本人能把漫画般一惊一乍的搞笑、堕落邪典的血腥跟骨科纯爱融合到一起…这些情节单看太离谱了但是想到作者是日本人只会细思极恐,每话杀人动机内核都是因为寂寞这真的很日本吧,所以一首开头曲完全都通用每个故事了)——二编:何意味我的兄妹骨变母子骨了??
人不能知道太多 所以人鱼篇什么时候上
快点把人鱼篇也端上来吧!!快点把人鱼篇也端上来吧!!快点把人鱼篇也端上来吧!!快点把人鱼篇也端上来吧!!快点把人鱼篇也端上来吧!!快点把人鱼篇也端上来吧!!快点把人鱼篇也端上来吧!!快点把人鱼篇也端上来吧!!!!
《翌日》系列的精神续作,不过也有可能比正统《翌日》系列出的更早。感觉玩法上已经脱离了传统的一本道走到底的路子,增加了一些QTE和小游戏。另外对话的内容占比大大的增加了,不像传统《翌日》剧情更多靠体会,《死期欲》的剧情主要通过人物对话发展,游戏体验更像是视觉小说的类型。整部游戏目前分为九个章节,游玩下来值得推荐。 第一话-女高中生失踪事件:一个喜欢男主角的路人女NPC的悲剧。 第二话-牛郎失踪事件:男主角后宫增加一名女连环杀人犯。 第三话-剪刀女连环杀人事件:幕后黑手的作恶初见端倪。 第四话-地下偶像失踪事件:男主角后宫增加一名女吸血鬼。 第五话-寄生面事件:男主角后宫增加一名女调查员。 第六话-4年前的事件:类似番外篇,主角好友的过去。 第七话-夜祭神隐事件:揭示男主角的妹妹并非亲妹妹。 第八话-梦魅事件:揭示男主角有人格分裂。 第九话-梦魅美美子失踪事件:揭示男主角人格分裂的原因,罪魁祸首是他的母亲。 《死期欲》的真正作用是咒杀所有爱上被诅咒者的异性,所以最终的结果是被诅咒者的家族绝后,还是很恶毒的诅咒。不过游戏结局提示剧情尚未完结,期待男主角与“妹妹”的结局,以及封印门背后的恶灵是否能冲破牢笼。
