Deemo II, along with a CCG called Soul of Eden, has appeared on Google Play for pre-registration.
Developed by Rayark International (of Cyto and Deemo fame), Deemo II almost certainly another piano-based rhythm game, though the trailer attached to the Google Play listing stubbornly declines to confirm this.
Instead it delivers a high quality anime in which a boy is chased by some weirdos, falls into some water, and is apparently rescued by a humanoid bubble.
Alongside Deemo II, Rayark has also put up Soul of Eden, the studio’s first esports title. It looks quite promising. Check out the trailer below.
