The Rising Of The Technorganic Hero

Naofumi Iwatani was falsely accused for doing something that he hasn't done. But when the Queen of Melromarc came to his aid, his name was cleared in front of the country.
For that, he was rewarded for being the lord of the demi-human land. He even decided to stay in their world, in order to protect those whom he hold dear.

Her powers evolved through and through when she is with them. She even realized that she was entitled as "The Herald of Primus". Her destiny is to stop an all out war between the two factions of Cybertron.
