Ryoga just clears right? I guess if it's a one Set match then maybe Byoudin can do it? But the longer the Match, the weaker Byoudin becomes.
I mean even Ralph was able to win a set against Ryoga. 6-2!!!
And we know Ralph is a full tier behind Byodoin/Volk/Medanore tier
You can say Ryoga might not be serious. But still.
Consume is being implied to have a weakness and limit. So, it is not like a sure win ability. I think it also needed time before it can be activated.
In Fact, Medanore is being implied to be immune to it. (Not saying Medanore will def beat Ryoga). But he is immune to it.
However, I agree Ryoga beats Byodoin cause of matchups.
The only ones who can even put a threat against Ryoga are: (imo)
Ryoma (Main Character Plot Armor. Jk. Lmao)
Medanore (cause of consume immunity)
And maybe Volk (cause he have strong Base)
Byodoin Base is significantly worst than Volk. In fact, He needed 8C to even compete with Volk's Base.
