Please tell me the names and sources of some cartoon handsome guys who show their navel (not bare-chested)

I have read many such cartoons, and now I just want to remember these ones.

Naruto is not very handsome and does not appear many times.

Ten Warriors of Makita BRAVE 10 Hiroyuki Kono, this is not bad. There seems to be other navel-exposed ones in it.

The devil's lover is full of handsome men, who often show their navel skillfully, but occasionally go shirtless.
