Yeah that's the equivalent of Lanji fans saying RS isn't a power up
Because of unconsistency.
Luffy tried to learn how to use ryou at Udon from ryou master.
But Zoro directly use ryou thank to the Enma . No need any learning and trainnig. This is huge Powerup
But when we are at WCI , when sanji save Beges wife, we have already seen sanji escaped carried Beges wife and hit Owen less than 1 second.
What kind of power up raid suit provide , ฤฑ cannot understand ?
