Hi. The context is that 神無月 disguised himself as a producer and invited 七罪 to
be a model.

Question: what is the function or meaning of the ときたものだ? I used to think the
ときたものだ has the nuance of 'add' or 'plus' and it is often used as a set phrase
with '～上に', 'おまけに', 'さらに', etc.

But this ときたものだ doesn’t seem to mean this. Could you please shed some light on
the phrase?

Thank you.




It's とくる followed by exclamatory-ものだ.

**～とくる (literally "it comes out as ～):**

Put together, ～ときたものだ/～ときたもんだ works as a little cliched way of emphasizing,
introducing or repeating a surprising statement. In other words, it adds the
feeling of "ta-dah", "lo and behold" or "holy crap" to the sentence. "On top
of that" is also usable when this expression comes at the end of a list, but
it does not have the meaning of "in addition" by itself.

I asked where he was, and believe it or not, he was like "I was sleeping at
home"!
