What is 'Daiblos Core'?

This work is a forbidden territory conquest RPG where mecha girls confront unknown threats.

In 2070, a new power 'NOVA Energy' was discovered from a meteorite that fell to Earth. As the 'Commander-in-Chief' belonging to NERI (NOVA Energy Research Institute), established for its management and research, the player leads an elite unit to explore the Shattered Star.

It features a highly strategic battle system where you establish battlefield superiority by arranging up to five members on a 3x3 grid, utilizing character skills and traits to build the optimal formation.

Furthermore, the story with the unique mecha girls is also a charm of this work, a title that fuses a detailed worldview with profound tactical battles.
