3. Osomatsu-san The Game: Hachamecha Shuushoku Advice -Dead or Work- おそ松さん THE GAME はちゃめちゃ就職アドバイス -デッド オア ワーク-  Otomate
Visual novel game based on 2015 anime adaptation of Akatsuka Fujio's 1962 "Osomatsu-kun".
"Osomatsu-kun" story revolves around the Matsuno sextuplets whose faces are all the same: Osomatsu, Karamatsu, Choromatsu, Ichimatsu, Jushimatsu, and Todomatsu. The "Osomatsu-san" revolves their story 20 years later, trying to survive in the middle of the modern era.
In the future, nations and civilizations have disappeared due to rising sea levels caused by tectonic movements and global warming. The survivors lacked technique and talent, but they were able to restore an ancient battleship and attach a spare hydrogen engine to it. Then, a long long time passed, and all land was inundated by the sea, and humans barely survived aboard the self-navigating self-repairing ship.
Ao is a boy who lived in the town aboard the ship. He helps out his parents with plowing the fields and fixing the fishing gear. There is no entertainment aside from visiting the floating market once a month and gazing at the passing ancient flotsam and pondering what they were once used for. It was a relatively depressing life akin to living in a closed society.
One day, he entered the ship’s engine area, which the adults had told him absolutely not to enter. There was a picture from long ago, showing girls in colourful clothes dancing at a school in front of a large crowd of happy children. This was a ‘culture’ which has long since been lost. Moreover, he found a girl sleeping within a capsule. She was wearing the same clothes as those shown in the picture.
The capsule opened when he touched it, as if he had authenticated something. The girl appeared to have lost her memories, aside from one thing: that she is an idol. An idol’s job is to sing and dance, and to spread happiness to everyone. Ao and the self-proclaimed idol Ai set out to revive the idol culture in this small world floating on the sea.

In 2027, advances in virtual reality technology have allowed for the creation of a ‘mixed reality’, combining both reality and virtual reality. It is not uncommon to see ‘virtual idols’ performing, and the most popular one is Ai, who was created using the newest state-of-the-art VR technology. Kanata is part of the M3 (Music Mediaworks Mate) circle of music lovers, along with his self-proclaimed guardian and cohabitant Kuon, and kouhai Asuka, who is interested only in weird ‘sounds’, among others.
One day, they were able to attend the huge virtual live event “Pure Song Garden” as part-time staff members thanks to the connections of Ritsu, a lady who lives in the same apartment as Kanata, and who used to take care of him when he was a child. Before the event, Ritsu brought them to the stage and did a start-up test for Ai as a special demo for them, but when she appeared, something felt off.
Actually, it was not Ai, but a beautiful girl Iroha who looked just like her. She said that she came from fifty years in the future for a short trip. Her ‘navigator fairy’ Suzu, a girl with fairy-like wings who accompanied her, explained that only Iroha’s consciousness travelled from the future and that she was only temporarily using Ai’s virtual body. At that time, there was a great commotion on the event grounds over Ai’s sudden disappearance. Iroha will have to take over Ai’s role on stage at the live, and Ritsu and the M3 members did their best to support her.
Everything was going smoothly at “Ai”‘s performance when a warning sounded and an unexpected error occurred! The “VR hazard” accident resulted in Iroha unable to return to the future.
