I feel like I should have done volume 4 first, though? I was told that chronologically the events of volume 4 chapters 3 & 4 take place after the rabbit squad stuff.
I've also heard it's supposed to be:
>first half of Volume 3 (Make-Up Work Club stuff Chapters 1 and 2?)
>Volume 4 Chapter 1 (according to
Wiki, it only unlocks after reaching a very specific part of the Chapter 3)
>rest of Volume 3
It would make sense because there is at least some time skip in the middle of Volume 3. (But confusingly I think it happens between Chapters 2 and 3, not in that specific part where Volume 4 unlocks.) I don't remember the exact details/sequence of events but Mika had enough time to "settle in" at the house arrest and spent a while eating only roll cakes (unless
fan works just ramped it up to 11 for comedic effect.) I definitely remember Nagisa saying Mika shall be fed only roll cakes, which I presume could count as
cruel and unusual punishment if done in a US prison. It's worth noting that Nagisa only did that after Mika's response to "let me help you get a slap on the wrist" wass being a cheeky little shit and complain about stuff like "she only has basic TV, not cable channels."
If you have (base) Mika unlocked, I recommend doing her bond story AFTER Volume 3, and whenever they have her trial in the story (I think it was in F, and honestly she does get the nepo-baby treatment from her connection to Seia/Nagisa/Sensei.)
(The Trinity students protesting Mika are still little shits piling on an easy target, they should've instead protested the systemic nepotism instead. Admittedly they may have been deliberately written as Strawman for the "Mika doesn't deserve a redemption arc" -position.)
