I just come back from the future. Chapter 26 is big plot twist and chapter 27 is where everything is explained why there is such a twist in chapter 26.
Wait how did Yabu manage to tie someone like Momo up without anyone noticing??? Was she carrying chloroform in her pocket or what? Thats the biggest headscratcher here.
Everything else seems to hint to Yabu being manipulated by someone who had a grudge agaisnt Jimi (a previous classmate/student of his??? Seems like they are related to Yabu). Idk the story isnt that thrilling tbh
