This manga lost me at the Shibuya arc, but dipping in it's stunning how much worse it got. Like they introduced a random ass tournament arc and just said "eh, lets just end it". So there has been next to no actual story for a quarter of the manga now, just confusing as hell battles. "oh, it's the domain, i'll reverse it and then do my domain! haha!...oh no, he reversed it with that secret domain and now I need to use my other domain again"
It's all gibberish. I thought Naruto and Bleach had bad endings, but they actually still stuck with a semblance of a story. This? It's just utter nonsense.
