Tentz

Tentz (テンツ) is Gantz's younger brother and lives with him and their mother in Parm. Although Tentz wants to appear as tough as Gantz, he is not as nasty in nature and feels in conflict between pleasing his brother and being a nice boy.

He has another older brother in the Garlyle Forces called Gontz.

Grandia Parallel Trippers
Tentz makes an appearance as a playable character in Grandia Parallel Trippers and can be recruited after the events of the Sky Isles. He can wield knife, whip and projectile based skills and like his brother can possess no magic but has the ability to use monster skills. Tentz is extremely weak and has the second lowest combined stats of any player character in the game only bettering his brother Gantz.
