Origin 4 (manga)

If I don't do something, everyone's going to die.

Origin arrives in Kyoto with Mai and Dr. Fermi, only to find the director of AEE’s A.I. Institute recalcitrant at best—but that’s the least of their worries after Origin’s robot brother GON shows up and goes on a merciless rampage! Committed to protecting Mai but unable to reveal his true identity, Origin must make a deal with the mysterious “data-mind” Y in order to find a way out of this lethal ordeal!
