Osta Akiba Lost PC

Live-action suspense game

A new frontier in live-action suspense games, combining a multi-perspective visual novel where you switch between characters, high-quality live-action cinematics, and immersive 360° camera direction.

The stage is Akihabara, Japan’s iconic subculture town. Game creator Shinjo has gathered six unique actresses who each embody the spirit of Akihabara.

Winner of the 2025 Japan Game Awards – Future Division.

Seven people, seven intertwined destinies. A grand ensemble drama performed by a stellar cast.

Game Creator: Daiki Shinjo / Hiromitsu Kitayama

Founder of Shirosawa Games. His debut title was a major hit, earning him the reputation of a "genius creator," but his later works failed to replicate that success.

He has two little sisters; the youngest Ruri was one of the six girls who vanished in Akihabara 13 years ago in a series of unsolved cases known as "The Akiba Vanishing".

With his life reaching a dead end, he declares that he will make a comeback by creating a game based on the very incident that took his sister away. Its title: AKIBA LOST.

Maid: Aoi Shinjo / Sayuri Matsumura

Shinjo's other younger sister who works as the manager of a maid cafe in Akihabara.

After Ruri's disappearance, she often clashed with her brother, who had immersed himself in game development, and they have barely seen each other for the past 13 years. Since graduating high school, she has continued to live in Akihabara, the site of the incident.

While usually somewhat detached, she occasionally reveals a tsundere side that captivates many of her customers.

Game Streamer: Yukimi Kurahashi / Momoko Tanabe

Working as a designer at Shirosawa Games, she has also gained a following as a streamer, which began out of her love for games.

A huge fan of Shinjo’s debut work, White Crash, she moved to Tokyo and practically beat down the doors at Shirosawa Games to get a job there. She looks up to Shinjo and co-founder Takazawa like older brothers.

Her Tohoku accent occasionally slips out during streams, which adds to her charm and draws in viewers.

Food Writer: Moe Kurosu / Misato Ugaki

A food writer specializing in Akihabara who explores the town through its food.

Originally a general-interest reporter, she became fascinated with Akihabara’s subculture about three years ago. She now introduces everything from long-established restaurants to the latest trendy cafes and unique eateries from her own perspective. While her casual outfits are accessorized to match her style, her tough, tomboyish personality is reflected in her beloved, rough and ready jeep.

Underground Idol: Kokone Nagato / Yui Oguri (AKB48)

An underground idol active mainly in small live houses in Akihabara. She belongs to the group Baby☆Macaron. While exuding the full charm of a classic idol, her ambition to succeed is unmatched. She distinctly switches between on- and off-stage life, often wearing high-end brand clothes and accessories in her spare time — a departure from her underground idol persona.

Shrine Maiden: Chihiro Jimbo / Azusa Ohara

A shrine maiden working part-time at Kanda Shrine, known as the guardian deity of Akihabara.

After an event in her childhood, she came to believe in the existence of gods and developed a deep gratitude for the city of Akihabara. She is also an avid gamer and easily clears even difficult action games. Calm and gentle, she has a habit of saying, "It’s divine..."

Cosplayer: Wakana Yusa / MINA (East Of Eden)

A cosplayer based in Akihabara. She has dedicated over ten years to cosplaying Lilica from the legendary game Magical Schoolgirl Lilica, fully devoting herself to the character. As a former returnee student from overseas, she is fluent in English and interacts easily with foreign tourists. With her cheerful personality and excellent communication skills, she keeps going ahead full speed on her Lilica cosplay journey.

Story

Thirteen years ago, six girls mysteriously disappeared in Akihabara — a series of unsolved cases known as "The Akiba Vanishing".

At the annual Tokyo Game Expo, Daiki Shinjo (played by Hiromitsu Kitayama), once hailed as a "genius creator," boldly announces the development of a new game inspired by this very incident: AKIBA LOST.

But soon thereafter, the strange disappearances begin again.

The cast of the game includes his sister Aoi Shinjo, who works at a maid cafe, underground idol Kokone Nagato, food writer Moe Kurosu, shrine maiden Chihiro Jimbo, cosplayer Wakana Yusa, and game streamer Yukimi Kurahashi — each a colorful icon of Akihabara’s vibrant subculture.

The story they were supposed to perform soon begins to bleed into reality.

It all starts with a threatening phone call — and the sudden disappearance of Aoi.

"Stop developing the game now. Or else...the tragedy will repeat again."

Can Shinjo finish developing the game? Can he protect everyone? Who is behind it all? And what really happened 13 years ago?

The choices determining how the story ends are now in your hands.
