Real Account Vol. 9 (Kodansha, 2018)

With the threat of the Derp Marbles growing stronger, Yuma's goal to discover his true identity becomes second to another: destroy Real Account. Reunited with Chiho and Nanako, and with just 27 hours remaining in Social-Network Tag, they struggle to find out what Marble, and Real Account, have been after. Along the way, they uncover unexpected answers–like the identity of the Derp Marbles, their connection to Yuma's family, and the true purpose of Real Account. The end of the game may be in sight, but reality can't be wrapped up so neatly.
