No idea, and nothing implies that he has any sort of relation to Ultraseven, their names not withstanding.

Neos and 21 were both designed before Tiga as part of a project intended to bring Ultraman to a (then) modern audiance. Neos is thematically supposed to be an updated original Ultraman, and 21 is supposed to be an updated Ultraseven.

In-universe, they have no relation at all.
