Info

Ookuninushi has always been an important member of The Cryptics. Although The Cryptics' work mostly involves research and development, it is inevitable that she will have to face Visbanes directly. To this end, she specifically designed a special combat suit for herself—based on astrology, and manifesting the power of astrological signs through Divine Grace and scientific equipment.

They called her the "prodigy" of Core City, the genius sensation in the research world who came out of nowhere two decades ago with her own original mecha inventions.She was subsequently admitted to Core City University without any exams at the age of ten based on several publications in top scientific journals and, at eleven, became a tenured professor and reached the pinnacle of her research career on the verge of turning twelve. But when everyone was cheering for her and looking forward to what great achievements this genius would make in the future, she vanished with a resignation letter on her twelve birthday.She has not returned to the university lab since, nor published in any scientific journals. A brilliant star seems to have vanished with her old office vacant to this day. Her picture still hangs on the wall: of a silvery, short-haired girl with lovely pink eyes like the sakura petals of early spring, staring at her latest design grasped in the hands of a mechanical arm with a smile.
