Ah yes, the old "Oh you see these guys who were previously portrayed as the peak of strength? They're weaker than a fly actually, THESE other guys on the other hand are truly super powerful and in no way weak" rinse and repeat. But combined with this stupid ahh decision to make them all have the power to copy and taking away the MC's only uniqueness plus the edgy kingdom hearts looking chuuni black coats that everyone on MC's side is wearing truly makes this some fine Isekai slop.
