Rainbow Resonance Pact

"I want a friend."

Hearing the girl's request, the consciousness within the crystal awoke. It made a pact with her, gained a body, and took the name Ston.

Well, it did get a body... but why does it look so much like a girl?!

With this nagging worry, Ston, who had probably been male in the past, sets off on an adventure in this new civilization filled with resonance beasts, as a special kind of resonance beast himself.

With the dream of forming a rainbow-colored resonance pact in his heart, Ston's adventure will continue.
