The Ones Within

Naka no Hito Genome [Now Streaming] (ナカノヒトゲノム【実況中】) is a Japanese manga series by Osora, serialized online via pixiv Comic website since 2014. It has been collected in eight tankōbon volumes by Media Factory. An anime television series adaptation by Silver Link has been announced, though as of late, the date of airing is uncertain.

Plot
A series of strange disappearances have been occurring throughout Japan, and despite the police's efforts, no leads have been found apart from the fact that all of the victims were youths.

Akatsuki Iride, a friendly and amicable teenage boy, is a popular streamer who uploads a "Let's Play" F2P (free to play) game called "The Ones Within - Genome". Although online rumors claim that the game causes anyone who clears it to disappear, Akatsuki is wholly unaware until he is summoned to a completely different world, where he meets other teenagers like him: popular horror-game streamer Karin Sarayashiki, Sengoku-period and Japanese-style game uploader Kaikoku Onigasaki, nurturing-simulation game streamer Himiko Inaba, fighter-game uploader Anya Kudou, puzzle-and-maze-game streamer Yuzu Roromori, stealth-type game uploader Zakuro Oshigiri and love-game streamer Makino Aikawa.

The eight teenagers are welcomed into what is known as the 13th Avenue, headed over by a mysterious man with an alpaca mask calling himself "Paca", and are informed of their task: to work together in clearing stages of the game and retrieving the "chromosome", a keycard-like token of completion, to subsequently reach 100 million viewers in this livestream where death and injury can all occur. Henceforth begins their trials in clearing this game, but what lies in wait for them is not only dangerous obstacles, as each member carries with them a hidden past and dark secrets of their own.
