Suzaku was a pretty good villain though his fight lasted way too long.
He used a magic whistle to try to break out of a prison set upon his world by Spirit World.
So it was Yusuke’s job to break the whistle.
Unfortunately for him, Suzaku was able to split himself in seven bodies.
And oh boy, Yusuke had to struggle pretty hard.
But Yusuke’s stubbornness managed to have him survive.
Shooting all of his life energy at him.
And his stupid clones too.
I guess he didn’t get an invitation for the Dark Tournament due to the disability of being dead.
