Earth, Year 20xx at a certain mansion.
Inside a room, 4 people can be seen standing before the entranceway of the room, all of them wearing a special cloth made from special materials. The 3 of them looked in anticipation to their leader.
"Ready?" their leader, a young girl who just finish celebrating her coming of age ceremony asked to her companions.
All of them nodded at her question and smile.
"Then let's g-" her words were interrupted by a sudden gust of wind inside the room cause by an unknown disruption and rift in space.
Chaos within the room soon happens. All furnitures were flown away by the strong wind and the girl find herself being pulled in into the sudden rift of space beside her. Her companions hurriedly tried hard to pulled her out from it but to no avail, their strength that is considered as one of the strongest in the world seemed to not matter against this sudden rift. As the girl was being continously dragged in, despair overwhelmed them but still, they didn't let go. To all of this, the girl in question remains calm, she realised that even she cannot resist the strong pull of this rift as such she looks at them and said: "It's okay. Don't worry about me, I'll be fine" then laughed a little. As she feels the force inside the rift that had been constantly pulling her in intensifies, she smile a little bitterly and said in a hurry " I guess this is a temporary goodbye, continue working hard and strengthen yourselves even without me supervising you. Don't let our squad name in shame! I believe you guyz!" With a determined look she finally told them "let go! I promise, i will return!" The three of them continued to play a tugged of war vs. This damned space rift. They looked at the girl in horror "yuuri!?" "No never!" "We will never let go!" They continue to rant but stopped upon seeing her serious face and hear her next words "this is my order as your Marshall" hearing this they slowly and unwillingly released her hand as per order. They cannot defy orders specially if it comes from their beloved and respected marshall. They cry. Yes, them who had hardened their minds from various battles cry like a child infront of her as they watch her smiling at them before finally saw her being fully swallowed by the rift.
Finally, silence insued in the room. They looked up, suppressing their tears from flowing even more. They know that crying won't solve anything anymore, That they need to pulled themselves up to solve this problem. Deep inside they knew that she will be fine, she's stronger than them, stronger than anybody else. They needed to report this, find ways to help and find her, become stronger and continue to believe that they will meet...no they will definitely meet again, no space can stop them and no one can stop her -their strongest Marshall.
Meanwhile....
The girl open her eyes to find herself lying in a dessert, all she see is darkness and two moon infront of her. Yes, two moon. She sat up and smile ' I'll be back' she thought and look around her in contemplation.
