About this game Read the full description
Sachiko Shinozaki, tragically murdered at age 7; such a sweet girl, taken away at such a young and tender age! Sure, she may have reacted by becoming a bloodthirsty, vengeful spirit responsible for the deaths of countless other children, as well as their erasures from history, but everyone knows that in her heart of hearts, she’s just an ordinary, innocent little 7-year-old…right?
Well, no. Because you see, today is her birthday! She’ll be turning…7 again, naturally. But in celebration, she’s decided to grant all her victims 24 hours of amnesty from their suffering by gathering them all together for a…hysteric? birthday bash. There will be party games, entertainment, adventure, and most of all, romance!
Join Sachiko and the lovable cast of damned souls from previous Corpse Party games—along with a few new faces—as they take the very concept of genre and toss it aside. Prepare to experience terror, discomfort, joviality, and confusion in equal measure as Heavenly Host Elementary plays less-than-heavenly host to cooking contests, co-ed mixers, interpretive stage drama, traditional party games, and Lovecraftian horrors alike.
Because you know what they say: Hell hath no fury like a 7-year-old girl bored…
A (surprisingly) canonical “midquel” to Corpse Party and Corpse Party: Book of Shadows, taking place sometime during the course of those games, Corpse Party: Sweet Sachiko’s Hysteric Birthday Bash recounts the bizarre events of vengeful ghost girl Sachiko Shinozaki’s one-of-a-kind birthday party held in the otherworldly school where so many lives have been lost in previous games: Heavenly Host Elementary.
The game plays out as a visual novel, divided into eight main chapters that each detail a different activity or cluster of activities. Player decisions determine which of the game’s endings is attained, with only one true ending from each chapter leading into the next. Surviving to the end will require thinking like Sachiko and making the choices that will please her the most…but with the fewest casualties.
Dark Comedy and Nonstop Fanservice
Put on a play, make a movie, attend a mixer, run a race, cook some curry, and more! Indulge Sachiko’s whims, and see new sides of fan-favorite characters in the process.
28 Endings Later

Extra Chapter Presented in Traditional Horror Style

Japanese Voices Like You’ve Never Heard Them Before

- Content warning
- This title is a horror visual novel where player choices affect outcomes. Contains excessive violence and gore depicted primarily via textual descriptions, and Japanese-language voice-acting, specifically including the mutilation, torture, and murder of children. Contains a few images with disturbing content such as bloody corpses. Also contains images of female anime-style characters with exposed underwear or cleavage, and, in a few instances, being groped by other female characters or monstrous tentacles. Contains textual descriptions of suggestive situations, often for humorous effect, such as masochism and a female teacher’s crotch being pushed into a male student’s face. Numerous examples of foul language can be found in translated text, including slurs such as "b*tch" and heavy swears such as "f*ck."
