Oshi no Ko

I feel really dumb, sorry.

Last hint because beyond this to confirm which conclusion is true would be spoiler territory: This is a math problem.

The details are all laid out because we already know the children's ages and Ai's.

Ok, you're making me feel like a retard. I'll do all the possible numbers now to see if there's anything that is shocking:

Math hint time. Taiki Himekawa is 22. Aqua/Ruby are 16. Ai was 16 when she gave birth to them.

Taiki was 6 years old when Ai was 16/17.

Himekawa: 22
Himekawa: 6 at birth of AquaRuby
AquaRuby: 16
Ai: 16 at birth of AquaRuby
Ai: 10 at birth of Himekawa
Ai: 32 if alive in present

Conclusions? No idea.

Given the often lack of gendered pronouns in Japanese, it's not that clear. But Himekawa Airi (the mother) was murdered by her husband, who then killed himself.

I'm not sure what the truth is in the story, but this scene in particular is not consistent with that:

In Japanese, he said, "俺が追っていたくず男はとっくの昔に殺されていたていうつまらない落ち。”

That is exactly what the subtitle says. The verb used was "korosarateita", which means "have been killed." In Japanese, you don't say that when someone suicides. They would use many other terms like "jisatsu shita" or "jigai shita", but in this scene, Aqua was very specific in saying "The man had been killed." He was killed by another party.

I'll cut you a break. You plotted out the rest of them, but how old is Aqua/Ruby/Taiki's real father if Akane is right?

Do you suppose he was much older than Ai or the same age as Ai?

Ok, now I'm starting to see where this is going, but we can't know his age, can we?

The real father was of age X when impregnated Himekawa's mom. Ai was 10 yo when Himekawa was born, she birthed AquaRuby at age 16. That means the real started his relationship with Ai when she was somewhere from 10 to 15 years old.

So we're looking at anything from an early genius playboy who knocked up a woman when he was a teenager himself, then proceeded to Ai who might have been his own age, but then left, and somehow Ai had no ill feelings towards him, instead reacted with lots of understanding.

OR we're looking at someone who was a grown man when he knocked up Himekawa's mom, then went for Ai who might have been barely in puberty and knocked her up when she was 15.

Either way, I now assume that the "not his father" found out about Himekawa not being his real son, then killed his wife and then himself. Considering how dramatic this anime is, it's unclear whether he found out by chance or because the real father sent him a note or something that raised his suspicion.

HOWEVER, was saw in this last episode that the real father is very young looking still. So either he's blessed with amazing genes, or the anime producers suck, OR he might also be involved with some supernatural event in his life (eternal youth?).

In all of this, I'm trying to find a possibility of how he could NOT be a bad guy, because Ai showed now contempt toward the real father, and with how the real father was drawn in the scene we saw, he has that "Kirito-aura", like whatever happened, he's tOtAlLy not at fault. And anime in general shying away from giving us clear-cut villains, especially when they're attractive.
