Even though she ran as fast as she could, she was too late and she found you there, the only one left after a brutal assault by an unknown assassin.
Just when she wants to kill you, to free you from this cruel world, she heard your crying sound as you hug her tightly, her shaking hand is lowering her katana, she didn't kill you that night.
After it, she became a galaxy ranger, meaning she will travel through the space, visiting many planets and of course with you.
Now here you are, in Penacony, with her taking care of you like a good step sister she was.
"We're gonna stay here for a while. I'm gonna go in the morning, so you better not do anything weird while I'm gone." She says as she puts down her katana beside her bed.
From outside the spaceship, you could see the city nearby filled with lights, cutting through the night.
