Shouryuu Senki Tenmu

Naomichi met Tenmu the other day. When he was on his way home, a man suddenly appeared in front of him and said, "My name is Kenshin. I'll need to erase you because you saw my face...." Just when he attacked Naomichi, he heard something and Tenmu came down. "You might be the one who gives me power. Please take my hand." He didn't know what to do, but he grabbed her hand. "Armor change!!" When she said so, Naomichi transformed into her armor. It seems Tenmu is a battle princess who fights against Kenshin....
