Well I can vouch that the story is nothing short of AMAZING!!!!! Lol well yeah I can say that vigilante drives its plot forward much better than the main series. But In the main series defence, Vigilante is bi-weekly so there is more time to plan the plot. One thing that bugs me mostly though is that it wasnt Koichi driving the plot at first. It was Knuckleduster lol
That is very much true... when it comes to Koichi it was more of a slow-burn character build taking place both for him and Kazuho respectfully. What I would love to see is an anime for Vigilantes given with how the story has progressed since the beginning, but I think they're gonna make an announcement of that either during the week the final chapter comes out or shortly after.
I'm still hoping for both of them to appear in the main series cause wow could you imagine Deku and Ochako interacting with Koichi and Kazuho? That would honestly be interesting. Plus Koichi would be like 25 in the main seres since I think at the moment we're like 2-3 years away from the timeline of the main series. The perfect way they could be intoduced is through Dectective Tsukauchi considering his involvement in the main series and specifically in Vigilantes.
In terms of the main series, I will say this War Arc has certainly been interesting to say the least, and part of me does feel it's a bit convenient that Deku just unlocked Float in that moment against Shigaraki, but oh well... Don't get me wrong I fine that he unlocked that ability, but I think the way it happened could have been a bit better handled. That still leaves me wondering how the rest of this arc is going to shape with this fight between Deku and Shigaraki.
All I want to say is I smell a time-skip on the horizon after this arc just know it!
I want to put in this spoiler but I couldn't...
