Little does he know, this discovery will plunge him into a world of perilous action, deep psychological exploration, and unsettling mysteries.

As the Sakura Scroll activates an ancient ritual, Kazuki finds himself entangled in a shadowy dimension known as the "Yamiyo," a realm born from the subconscious fears and desires of humanity. Teaming up with unlikely allies, including Kaito, a charismatic ex-samurai turned rogue, and Akiko, a tech-savvy shrine maiden, Kazuki must navigate through this treacherous realm to uncover the truth behind the enigmatic Shrouded Sakura.
