A New Light: Part 2 (新たなる光 全敗 Aratanaru Hikari (Kōhen)) is the second episode of Ultraman Dyna.
Shin ponders his role as Ultraman Dyna and a member of Super GUTS, while the enemy Spheres prepare and launch a second attack on humanity.
On Mars, Ultraman Dyna continued his fight with Neo Darambia, while Super GUTS observed the fight from their jets. He successfully destroyed the enemy with his Solgent Beam. Dyna then disappeared in a display of light and unbeknowst to anyone, left Shin Asuka in his place. With their mission finished, Super GUTS captain Gousuke Hibiki ordered the group to return back to Earth. Shin was troubled as to why he was chosen to be Dyna's vessel, while discovering the Lieflasher on the ground in front of him. Meanwhile, another group of Spheres began to combine and head for Earth.
TPC held a meeting with captain Hibiki about their new enemy, which they dub Spheres, asking him if he had learned anything integral from his encounter with them. Hibiki was only able to say that he believed that the Spheres were intelligent and that they're unhappy with humanity's advancement. At the same time, the Spheres from before were revealed to have landed in a volcanic area, seeping into and merging with the nearby rock.
At the Super GUTS headquarters, the team named the new giant of light Ultraman Dyna. Hibiki returned to his team and scolded Shin for almost getting deputy captain Toshiyuki Kohda killed, warning him to not to become a burden. Later that night, Shin was discouraged, but given advice by Ryo that they need to work as a team, comparing it to baseball, a sport Shin never won a game of when he was in school for the same reason.
More Spheres were then discovered near an observation satelitte, so Hibiki, Nakajima and Kariya head there in a ship, but find they are too late and the satellite had been destroyed. It turns out this was a distraction to draw attention away from the Spheres on Earth which had transformed into the monster Giralen, who was heading for a geothermal energy base. Hibiki allowed both Ryo Yumimura and Shin to return to Earth to engage Giralen, while the remaining team would take care of the Spheres. As Ryo and Shin departed, so did a small group of Spheres. Shin offered to fight them so Ryo could make it to Earth, but his jet is damaged in the battle, immobilizing him. Shin then asked Dyna to lend him his power, embracing the responsibility of having the power to protect everyone and transforming into Ultraman Dyna for the second time.
Ryo reached Earth, but was unable to harm Giralen, even when the trainees of Training Squad ZERO violated protocol and entered the battle in their test fighters to aid her. Ultraman Dyna then arrived to defeat the monster. Dyna struggled against Giralen's hot body and flame attacks, so he turned into his Miracle Type to counter them. With its enhanced speed and psychic abilities, he managed to suspend the beast into the air. By reflecting a fire breath attack from the airborne Giralen, he destroyed the monster, which also caused the remaining Spheres to retreat.
Super GUTS returned to TPC's base and Hibiki ordered Ryo to pick up Shin, who had been stranded on a beach after his fallen spacecraft landed in the ocean. There, Shin reminisced about his missing father's words, realising he had now seen the same light his father once saw.
