Plot
in 2063 A.D., Zack gathers at Mousanish Spaceport along with the other members of Group B-5 except for Aries Spring and Kanata Hoshijima, the former who joins them shortly afterwards and introduces herself. The teacher then introduces Quitterie Raffaelli and her younger sister Funicia Raffaelli who will be joining them as part of a unique task to take care of and teach a younger child. Once Kanata has finally arrived, the group then boards a spaceship to begin their four hour journey to Planet McPa. Once they are able to move freely around on the cabin, Zack asks if there is a shower on the ship. Upon landing, they exit the spaceship and walk around for a bit when Luca Esposito points out a strange globe that's been approaching them. They try to run away from it, but the strange globe is able to absorb and send them all into outer space.

They are able to find a nearby spaceship and upon collecting their luggage, are able to board it safely. When Kanata asks if everyone is here and if they're hurt, Zack says that there is one person missing. Ulgar Zweig looks outside and sees that Aries is still floating outside, with her thrusters and communications unable to work. Kanata volunteers to go out and rescue Aries while the rest of the group watch over the cord tying him to the ship. He is able to successfully grab Aries and bring her back to the ship where she thanks him repeatedly. As the group wonders how they can get out of their situation, Zack is working on the ship's coordinates and finds some disturbing information. He says that they are no longer above Plane McPa and that they are 5,012 light-years away from their original location. The group could do nothing but react with shock at this news.
