Gonna guess Aoko vs Alice, Aoko/Alice/Soujyuro vs Lugh, and Aoko vs Touko?There's like three big fights overall so, Mahoyo is a little weak in this aspect.
It wouldn't necessarily be a problem but the way they are structured throught the story kinda messes with pacing.
That's one of the few issues i have with it, and it is mitigated by the quality . They very much went with quality over quantity .

Pacing was pretty weird. Don't get me wrong, I enjoyed chapter 5, but it was hilariously long compared to the rest of them before it.
