Wado did cut kaido so did sandai so did enma
Onigiri is a 3 sword move
So why does he need "to draw Enma's power"?
If he have blades that can cut Kaido, why did he give away Shuusui for a blade which was special BECAUSE it was able to cut Kaido?
You see the problem here, right?
Enma is a "power up" just because. No real reason at all for it to exist. Only to wank Oden even more.
Zoro learned to cut steel because he NEEDED it to beat Mr1 at the time.
He learned Flying slashes because he NEEDED to beat Ohm ranged attacks.
He used Asura because he NEEDED it to beat Kaku.
Since the timeskip, like so many like to say, he never went all out. So why the fuck does he need this out of nowhere power up magical sword? He knows about the black blade already, he temporarily forged them against pika, but he needs to get strong enough to make them permanent.
That was the next logical step for him to grow, possibly during this fight right here with the yonkos.
But NO. in the middle, magical powerful sword that can cut kaido.
And apparently he still needs to unlock the permanent black blade to be able to do serious damage.
Why, WHY this trash development in the middle of the process?
