@skilodracus From my point of view you people are overreacting. I'm perfectly fine with this, and for once I know there won't be any character development, remember: we already know Nikaido have Ultra Instinct when protecting Tadokoro, this is nothing new, maybe new for the character, even though it shouldn't be.
I also don't think this enough for this much criticism, even though it looks more like a meltdown than criticism, but anyway, because this was bound to happen sometime or another, world is not rainbows and flowers and the last bully got taken care of in a very cringe way, so antagonization was inevitable.
Again, lets just enjoy the good moments, no need to be all up and armed for something like this.
