Oh... I'm pretty sure that he wouldn't have chosen to be free if he knew that it would also mean losing his memories of Tae.
Still weird how he brings back Nisshi first in hopes of him 'explaining things' and then leaves himself. You'd think that he would first make sure that Kishimoto and Sei would be resurrected, but I guess it isn't easy being a saint to everyone
Not really looking forward to a Gantz arc without Kurono ;(
