Goku Midnight Eye - S01

When private detective Gokuu Fuurinji is contacted by Ryoko Kadoma about finding her missing brother, Ryuu, Gokuu knows this is no ordinary case. Ryuu was the victim of a cruel genetic experiment and, without proper treatment, will soon become a mindlessly violent superbeing. Armed with the world's most powerful supercomputer implanted in his left eye, the detective sets out to find the missing boy. But as the case grows more complex, Gokuu is forced to question whether Ryuu can be saved, or if he will have to kill him before he fully transforms.
