arguably the best black clover opening?

Not really I'd say this was the best black clover opening, at least IMO.

Haruka Mirai Black Catch Black Rover those 3 are the peak in whatever order you want imo (but they're all FANTASTIC)

Not arguably imo

Already knew what it was as soon as I saw the headline. This opener is incredible

This one😤

I'd say Black Catcher is #1

All Black Clover openings are equally good

Guess Who's Back by Kumi Koda slaps too.

I personally think "guess who's back" is their best OP but this one is up there too.

Better then black catcher
