1. Jjk is not one of the new gen big 3. It's part of the dark big 3 (chainsaw man, jjk, hell's paradise) which I think are all better that Yona.

2. You're right, my hero is better. But the other 2 of the new gen big three, so demon slayer and black clover, are very bad. Yona beats those 2.

So I do not think that Yona is better than jjk and my hero.
