Bonkers, but really, really fun. In fact, now that I think about it, this manga really feels like a cross between Azumanga Daioh and Cromartie. This one is I will absolutely continue reading. There are many chapters where hardly a word was uttered, which reminded me of Yotsuba & at its best. The art and the action takes the center stage.
There are absolutely a few jokes that are going over my head, but the general atmosphere and the physical gags really get me and make it all still work when there is some cultural joke or word play that does not register with me yet.
