Futaro face = OMG she almost eat me face.

GG get rekt old man

Itsuki side 4?

boy I sure do love Girl Whose Personality Is Entirely Dependent Upon The People Near Her

Does itsuki just called uesugi dad father???

While the father's appearance has felt sudden, as many people have stated before, at least the extra chapter helped close this arc nicely. And it's a nice call back to the grandfather with being able to tell them apart. The father can't because he doesn't even know them, and so didn't even realise it wasn't Itsuki he was talking to.
The fact there was no kiss though, I can't tell if we are being trolled or not. It may mean that Itsuki isn't a possible final girl, it may also mean that it's held off till the end if she is. There's multiple sides to this, multiple viewpoints to consider, and it's going to undoubtedly spawn countless theories on what it means.

ITSUKI WINS AGAIN BABY

So he really is the father, I really tought he was a creepy stalker or something

Oh no... Itsuki victory confirmed.... Ooooh noooo....

Drop dead old man.
hope you stubbed your pinky toe on drawer with needle between your nail.

She didn't kiss him. That's kinda bad. Did her ship sunk?

Get fucked, you bald cunt.

Did she kiss him while going downstairs or just passing by?

Ideal? Ideal what? Ideal husband? Hahaha let's jump to conclusion!

Damn that old man is really the father...wonder how many bangings were done to make a quints and it's creeping me.

Shiiiit. Itsuki won. It's over. 2nd worst girl won.
