Rihito decides to receive the operation to turn him into an Ace. This is the decisive moment in history that the time travelers wanted to change, but knowing what they know now, they cannot agree on what is best for everyone.
If your stars are so precious,
why do you not protect them with your life?
Wieso hast du deinen
Stern nicht verteidigt,
Si tu tiens tant à tes étoiles,
Se suas estrelas são tão preciosas,
por que não as protege com sua vida?
