With the You of this World, and to the You of That World

The song that serves as the backdrop for the credits roll in Ar nosurge: Ode to an Unborn Star's true ending, and therefore, it's the canon ending theme to the game. This Song was crafted and sung by Ion as a demonstration of gratitude for her friends, though it's possible the player won't think it complies with the actions she does in the game due to being one of the possible alternatives existing in the Fifth and Sixth Dimensions, despite she stating several times during the game that she wishes to go back home but won't do so at the cost of sacrificing everyone else.

After Prim revealed to the Seven, Ion and Nero it was possible to have the latter two sent back to their respective worlds without requiring ridiculous sacrifices if they headed to the center of the universe and sang alongside EXA_PICO, Ion was initially hesitant about going back to her world, but after Earthes and all her friends convinced her it was okay for her to go back to her world, she broke down in tears from the conflicted feelings this gave her. After she calmed, she sang this Song for her friends. However, that's not everything: aside of containing Ion's wishes for the well-being and bright future of her friends and the newly reborn planet Ra Ciela, it also serves as a prayer where she appeals to EXA_PICO itself for Its help in moving across dimensions to find her way back to the Earth she was born in.

Additionally, as it should be clear from the explanation given above, this Song is actually dedicated to two groups of people: "the you of this world" are the friends that supported Ion ever since she came to Ra Ciela so long ago; and the "you of that world" is "you", the player who controlled Earthes and who always made sure to keep Ion safe and happy. And since "you" hold the power of Oversight in that world, everything "you wish" to happen become a reality in it, so if you unwaveringly think that Ion will have a happy future once she gets back to her world, that's how things will turn out to be for her.
