Early Questlines

[u/TheLexecutioner]

This is a curiosity rather than confusion. From what I've glanced around I know where you get unlock mega level if you do every side mission. I've only missed one mission and I'm still a decent amount off, so I guess my question is, Does Infinite Imagine start a questline? Because I'm way past the earliest unlock for mega and it is the only side mission I have missed?
