Goku Midnight Eye - S01

Private detective Gokuu Fuurinji takes on a case when Ryoko Kadoma hires him to find her missing brother, Ryuu. But this isn't just any disappearance-Ryuu was subjected to a brutal genetic experiment that will soon turn him into a mindless, violent monster unless he gets help. With a powerful supercomputer embedded in his left eye, Gokuu begins his search. However, as the investigation grows more complicated, he starts to wonder: can Ryuu still be saved, or will Gokuu have to stop him before his transformation is complete?
