The ONLY thing that I have a hard time believing is that the squid didn’t bleed from having MULTIPLE MASSIVE HOLES THAT GO IN ONE SIDE AND OUT THE OTHER.
I get that it’s an S rank monster and has high vitality but it didn’t seem to have an auto-regeneration effect so it just bewilders me.
If you know anything about squid anatomy, you'd know you can blow holes in the sac and just merely inconvenience it.
Everthing that's important in a squid is sat in the head, which despite its eyes is a lot smaller than people think.
Which is why you can literally kill a squid with one well-aimed sharp tap in the right spot.
Which is a thing all fishermen dealing with them know, and is
supposed to be part of Superior Nippon Nowledge.
Which is why the kraken dies after one single blow.. Not a One Punch Idjit reference, just normal fishery knowledge.
Which also means the MC either was fartassing around, showing off blowing useless holes in the thing, or was really lucky... But that's Plot Armour for you....
If he'd aimed right above/between the eyes where the "frown" is on his first attempt, we'd have saved a chapter, but have had less time for the harem to "Oh Dear, Halp!! , Our HeroHubbie is in Danger!!" .....
