Another suggestion. Thanks very much!

I have briefly checked most episodes, but found only few and brief scenes. I think also sitting scenes.

Aka "Bokura no Yuuki", Japanese title:  "ぼくらの勇気 未満都市" or shortened "ぼくらの勇気" English titles:  Our Courage / Keys to the City - The Kids are in Charge; Miman City. There is also a 2017 sequel (which also needs to be checked).

Rating 5-6 for now. Are there even better scenes?
