About This Game

Six months ago, a sudden monster disaster devastated the city.

After the catastrophe, the monsters fell completely silent—and Mika, the girl you had been searching for, vanished without a trace.

Just when your investigation reaches a dead end, a mysterious woman named Xao suddenly appears before you.

She reveals that the monsters are connected to mysterious “Crystals” originating from an extraterrestrial civilization.

But there’s one unexpected catch:

To awaken the Crystals’ true power, you must create a romantic resonance with girls?!

To find Mika and stop the monsters from awakening once again, you have no choice but to dive headfirst into an adventure where romance and battle collide!

Xao, the heroine of Kaiju Princess, will appear in this game, but you will not be able to build any kind of relationship with her... If you're interested in her story, please experience it in the original game, Kaiju Princess.

💟 Gameplay 💟

Experience a live-action interactive story from a first-person perspective, where you will meet multiple different girls and build relationships with them.

Every conversation and decision you make will influence how they feel about you—and determine how the story unfolds.

But romance isn’t your only challenge.

You must also harness the power of the mysterious Crystals to fight, defeat enemies, and gradually uncover the truth behind Mika’s disappearance and the monster disaster.

Fall in love. Build your resonance. Gain new powers. Save the world!
