Dolph Tasta, universally nicknamed "Rednose," hails from the Terran planet Peroma. His distinctively prominent red nose inspired this moniker. During the cadets' survival test on the derelict spaceship Esperanza, he acted as peacemaker, mediating tensions and preserving group cohesion against rising suspicions and external dangers. After passing the test and entering the Cosmo Academy, he pursued law. He ascended to become an Interstellar Court Judge, capitalizing on the impartiality and conflict-resolution aptitude showcased during the Esperanza ordeal.
