What ideas do Ты have for an escort mission?
Here's several characters I've thought of as potential people to escort:
Pais(Akame Ga Kill!)
Ritone(Akame Ga Kill!)
Chelsea(Akame Ga Kill!)
Here's thing I thought of at least when Sora escorts Chelsea, if she takes too much damage, she dies for good(Which is how it works in Akame Ga Kill!) without giving the player a game over.
If Sora succeeds in escorting Chelsea, I would expect at least some positive things to happen.
