About Exstetra
Exstetra is a fantasy RPG set in Amazia, a Tokyo fused with another world and fated for destruction. You play as Ryoma, a high school student chosen as a savior called a Prisma, and fight to save two worlds from ruin. You find companions drawn into Amazia from the real world and awaken their powers as Prisma Knights with a kiss.
Explore Amazia
Amazia is a beautiful but decadent world where Tokyo districts such as Shibuya and Akihabara have merged with another realm. Its labyrinthine dungeons contain monster battles, obstacles, treasure chests, and materials and items to collect. Gather equipment and strengthen your party as you make your way toward each labyrinth’s deepest reaches.
Fight as a party
Battles use a turn-based command system. You can field up to four characters, choose their front- and back-row positions, and select their skills. Party formation also includes companions held in reserve, and relationships with allies can affect battles. You can use auto-battle to move through fights faster.
Unleash EXS Arts
As the Prisma, Ryoma is the only one who can absorb EXS, the source of power in Amazia, by defeating enemies. He can share the EXS with Prisma Knights through a kiss, awakening their powers. Kisses with companions also release EXS for powerful special attacks called EXS Arts.
Develop your strategy
You can combine skills found on weapons, armor, and accessories to expand your options for attacks and support effects. Gather materials and refine your skill setup to take on powerful enemies.
