Glad the author did justice to these two girls who usually just a Komi & Tadano companion.
I thought they're just going to showed up for atleast one or two panel in this arc (because you know, different class problem and all). And just when I thought that there's going to be no development between their friendship while being away from our protagonist, the author pull a fucking wholesome YU-GI-OH trap card on us and not just give us a few page worth of fanservice, but the WHOLE FUCKIN' MINI ARC OF IT.
So Thank you Mr. Author-san, very cool.
P.S. this chapter makes me think that Yamai is actually just a normal girl after all (not when she's thinking about or around Komi-san anyway).
