He was cut vertically so I'm happy that opportunity wasn't wasted. It's a shame he's actually dead when the tournament had seemingly avoided that so far, we already got Shuumatsu No Valkyrie for the death matches.
I did NOT expect the fusion dance backstory, that was interesting.
All the complaints about 'This is the worst fight!!!' are hilarious, it wasn't a fight, it was just Muramasa's introduction, not every single 'match' of a tournament need to be a real fight, you need to have something the later rounds.
And stop crying that a japanese author isn't self flagellating and making all japanese characters bow and scrap in terror before getting curbstomped by some irrelevant figure none of you knew before he showed up in the manga.
It would've been one thing if he split Ahura Mazda and then fought both halves as they separated like a reverse Zerofuku from the main series
It specifically would be a bad thing because it'd do nothing to hint at and making you wonder about Muramasa's ability for his actual important fight. It's like nobody here ever heard of 'set up'.
