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.
