Synopsis
Ikagawa Togake is a boy with a superpower. He has the the ability to change the color of his eyes whenever he closes and reopens the eyes. Kinda useless, right? Regardless, Ikagawa Tokage strives to strengthen his power in an effort to become the strongest and not have his power be nothing more than a parlor trick. With that desire in mind, he trains daily in an abandoned building in modern day Tokyo. But on one such day, he comes to what looks to be a scene of a crime and feels the culprit might still be nearby. Will he make it out of the abandoned building alive? Is there more to his power than meets the eye?
