Character History

A Monstone was unearthed by Takamichi Crystalia 30 years ago. It merged with him and threatened his life. King Oradin brought him back to Crystalia and implanted a Kiramai Stone into his body to counter its harmful effects.Episode 13: Great Underground War

When Meteorite Jamen attacked Earth, Takamichi unearthed another Monstone. Sensing Meteorite Jamen nearby, the Monstone approached and merged with him, granting him the power of generating melting heat.Episode 12: Wonder Drill Boy


A Monstone is a stone with instinct, no sentience, thus according to Takamichi Crystalia a Monstone is a pure stone. They seek for suitable bodies to merge. If they merge with a Jamenshi, they can enhance the power of it. But if they merge with a human, they could endanger their life without proper intervention.
