Kaii-Roku: Yokai Hunter RPG GAME

【Seal the Yokai, UMA & Creatures of the World】

Kaii-Roku is a Japanese-style monster-collecting RPG where you
explore, seal, and collect 300 creatures — from traditional
Japanese yokai and cryptids (UMA) to gods, demons, and spirits
from mythologies around the world.

Behind an old shrine, inside an abandoned school, deep in a
forgotten village, a haunted forest, and a silent lake —
journey across 5 eerie locations and face the creatures lurking
within.

With simple yet satisfying timing-based battles and the thrill of
completing your collection, Kaii-Roku pulls you into a dark and
mystical world of Japanese folklore.
