He ends up meeting Saki, a dying girl whom he unknowingly cures, and then becomes the lover of. But when his memories return, he callously [[KickTheMoralityPet murders her]] as if to reject any possibility of him growing to have any kind of decency or goodness in him. Doing anything to gain power, Radiguet aids the Jetman in killing Juuza, and takes advantage of the Jetman defeating Tranza, his rival, to torture him to insanity. Gaining a lustful obsession with Rie, Radiguet brainwashes her into becoming a fellow Vyram, intent on making "Maria" his servant. And when Rie manages to regain her memories, he spitefully kills her to prevent her from being with anyone else.
