Remembering the Future - Part 2 (未来の思い出 後編 Mirai no Omoide Kōhen)
Taiga and Filis continue to talk about Mebius, who Taiga has heard much of during his training days. Filis tells him that when Mebius first returned from Earth, he was bothered by something, which was probably the difference in lifespan between humans and Ultras, meaning Mebius' friends would pass away a lot earlier than he would. Filis then reveals to Taiga that the Triger Shot came to the Land of Light after being sent by Mebius' friends through the use of METEOR technology, despite the Land of Light being 3 million light years away.
Filis opens up the capsule containing the Triger Shot and explains that in addition to being a gun, it also comes with voice messages, though they are distorted and cut. Filis tells Taiga that he was like Mebius, who had been entrusted to protect the Earth in place of the Ultra Brothers. Taiga feels encouraged by Filis' words, and leaves to go on with his training.
