Probably best extra's I ever saw, every chapter really gives alot of development to side characters of this manga, once again thanks Hokuto no Gun for such marvelous pace!

I've checked that too, but Sakura Yakiniku is Japanese style restaurant, they don't use chairs and high table.

Yabako only started Danberu around volume 19: https://mangadex.org/chapter/469880/13 so by the time this chapter was released there's totally no connection between two series.
