Okay, so the last time I commented I said I was still waiting for that one extra thing to make this manga "great". This chapter has that something extra in spades~
Ichika's dumbfounded expression to the tickle torture.
The realization on page 8 that they're both Yandere
for Aria-chan.
Just, the whole first panel of page 9.
The art on page 10.
The increasing Yandere
vibes.
Page 18 and 19 "Am I just lewd?" (Don't worry, we all were thinking the same thing, Ichika!)
More Yandere
glaring/confrontation.
Then the joining forces, Sakuya's smirk, and Aria's shocked reaction.
Oh and a last bit of Yandere
bonding and a plot hook for good measure.
And while I mentioned one page specifically, the art is the usual amazing quality throughout the chapter. Oh my god I love this so much.
