I kinda like the fact he isn't super overpowered all the time (As of now) it gives some actual stakes when he can run out of ammo or when his guns aren't strong enough to kill certain enemies. The cost benefit of his gear is an interesting concept.
Sweet, wholesome, and just genuinely makes me happy. Love the characters and their interactions, and honestly I actually really like the art, makes me feel nostalgic.
Honestly I don't even mind the extra chapters, all it means is more content and cute art. Some of the extra chapters have some of my favorite panels of the manga lol
