I feel like the manga skipping files 20 (T is for Templeborn) and 21 (A Midterm Report on the Mysterious) might cause issues in the future. It kind of makes me think the manga might be trying to get to file 26 (Accomplices No More) quicker for an early ending (I hope not though). Benimori is just going to come out of nowhere, since the manga hasn't even mentioned Sorawo's university seminar. Unless the manga just decides to leave her out entirely? I don't think there's room to adapt file 20 at a later point without really disrupting the pacing, considering it's the longest arc in the series. Maybe file 21 could be adapted later, and that could be how it introduces Benimori? It just makes me a little worried about the future of the manga. Hopefully I'm just overthinking it.
