What if this line is meant to foreshadow Nefertari Lili? We know that Jarul is over 400 years old so could it be possible that he met Lili during his younger years? (Toki might've sent Lili forward into time and that's how she disappeared). This could also explain why Imu wants Jarul dead so much.

Was this line meant to be a simple gag or is this foreshadowing for something?

Was there any deeper significance to this line? Or is it just there to tell us Jarul's preferences without any deeper meaning?

What's /isekai/ opinion on adult woman?

What did he mean by this?
