Hortensia Saga is a 2D mobile game which SEGA launched a few years ago and still running in Japan right now. We have no idea why, but SEGA later announced a reworked version in full 3D, Hortensia Saga R, along with a new anime series. Co-developed with local studios f4samurai and Eggtart, Hortensia Saga R is closely tied to the anime series, infusing tons of footage to showcase the game lore.

Essentially, Hortensia Saga R is a turn-based gacha mobile RPG with characters and scenes from the anime series. The flashy special moves are only really seen in the game though. Battles are fought on a grid battlefield, with players able to choose where to place each characters before the fight begins. Other than the strategic battle, other features touted include the 3D rework and several ways to grow characters. It is unknown if Hortensia Saga R will launch overseas, so stay tuned!
