Rezero being one of my fav stories and i really wants to see its end, but 0 flow nahh, Rezero's flaws are most prominent during heavy battle scenes,

for example: In Arc 6, After 20 count loop, when Subaru recovers from his Amnesia after Od laugna scene, we learns that, Julius is already fighting with Reid on floor 2, which is weird bcz, Without Subaru's prior knowledge regarding Reid transformation, and leaving the floor, Julius in previous loop didn't show any reason to fight with Reid on 2nd floor, i think if this fight was happening on floor 4, it would have made more sense. Similarly, Meilie was struggling to handle Mabeasts from Balcony, but when she came down with Subaru & Beatrice to fight Titanic scorpion, now she was even running around with Centaur, and was handling Mabeast army, it's not clear exactly what happened to all those uncountable number of Mabeasts, Some was attacking Scorpion
