I looked at the poster for almost a minute... and only guessed right because the black-haired girl was so awkward, but at not a SINGLE moment... I guessed who she was and much less expected this reveal.
With how crazy this story became so far back, I never would have thought it would come to this... but that is on me... because this last arc is literally about second chances, but I was so focused on the others, that I completely forgot about Fuuko's own second chance.
I see the semblance between mother and daughter.
