>>75938645Aqua mentioned it years ago, it's not that she doesnt want collab, but most of the time, the others are just too reluctant to invite her for collab.
Since they are afraid they'd scare Aqua off instead, and since she's like one of the older senpai.
Aqua is more of a shy and social inept than an introvert (introvert as in prefers to being alone)
