Instead of taking 1 step forward with the story, it takes 4 steps/eps back before where S1 ended and because of that we revisit and redo old issues that were already solved in S1, but those issue were nowhere near as pronounced/bad as they were in this, I guess this is like some kind of side story that explains how those were solved, except they don't because they differ from the original.
Anyway, the MC is just as annoying if not more, battles are more battles of the mind and/or words, typical cliché shonen stuff, but it at least makes a bit more sense than those, since his power doesn't come out of nowhere and it's not "the power of friendship" either.
The best part of it (for me) was the negligible amount of romances, and that's just sad. 5/10
