I just realized what this feels like. It’s One Punch Man’s Monster Association arc. 4 years of just endless nothing battles with side characters you care nothing about.
It’s the same feeling of getting to the end of the chapter, then getting depressed things haven’t gone back to normal.
This Arc wraps up quite nicely - we get a very good payoff for all of the combat which is mostly being used as a set up for tension (and to break up pages of exposition and flashbacks).
I agree with you in that I've read enough Manga that I give nearly zero fucks about "Look at these cool action hero moves! Don't you wish you had a power level like me, kids at home?!" stuff
But this series, like the One Punch Man Webcomic, is about the drama, the dialog, and the stakes happening WITHIN the combat rather than having a bunch of boring karate chopping pages that the ShounenSlurpers love.
I do like when abilities are used in intelligent, clever, or creative ways though.
Just breeze over the combat pages themselves and look for the character interaction, the dialog, or - as the author often points out - the way that they are fighting that shows their actual intent/personality (often holding back because they don't actually want to fight, buying time, engaging in dialog with the faintest hope that they can reason with the hunters).
If you're just here to see boobies - he put them in this chapter.
Hell, he even gave us at least 2 or 3 decent gags/jokes in this chapter as well for those of us here for the comedy!
(God bless your poor soul if you read Murata's 'DBZ love letter' Manga version of One Punch Man instead of the Webcomic)
