the only one that comes to mind rn is https://www.mangago.zone/read-manga/eleceed/
Its really fluffy their friendship literally makes me sob, the MC isn't really OP but he is pretty strong, and the art style is also really good.. has 300+ chapters and ofc if you like cats and all of the above... this might just be it
alsoo they fight ALOTTTTT so its really action-packed imo
not on mangago, but my my s-class hunters seems to fit the power of friendship type dynamic!
instead of the mc getting op and being a prince-type character, saving everyone all the time, he's supported by a bunch of different types of people! the plot is very interesting, and there's a bunch of action as well :) hopefully this helps (๑•ㅂ•)و✧

maybeee 100+ chapters (or enough to binge—no less than 60!) action manwha that (as embarrassing as it is) has some form of fluffy friendship/power of friendship type dynamic? kind of like mercenary enrollment where mc is overpowered but has a lot of people on his side ! i’d also prefer if the art style was HOT (≧∀≦) idk, for reference i’m reading devil returns to school days and i love the story but i’d like more light moments too !
