Wrong, that is what funi sent Toonami, clearly funi had issues getting the rights to broad cast the songs so they just made their own for the dub broadcast. The fact the subbed version on their website has the op/ed supports this. The people at toonami had no idea what they got wasn't the same op until people messaged them about it, and to be fair the only reason we knew it was changed was due to the episode leaking
Rather it not being the song that was known to be the OP music for months.
