After being killed in a satellite explosion, Rento was revived by Tregear to exact his revenge on the Cozmo Technica president Imazato. He appeared a month after the incident and faced against E.G.I.S. members Hiroyuki and Homare, who was assigned to protect the president. When Rento becomes Galactron MK2 and fought Taiga, Titas purify his spirit by reuniting him with Nana, allowing them to pass on to the afterlife. With Galactron and a descending satellite destroyed, Titas had a brief fight with Tregear before adjusting his life as Hiroyuki's second Ultraman.
