Yu-Gi-Oh! Judai, you call this a hero?

He traveled to Neon and became a boy named Yuki Judai.
I thought I had simply traveled to a parallel world and happened to have the same name as a protagonist.
Until that day, [Yubel] appeared in Yuki Judai's life.
"Judai, my beloved, I will always stay by your side..."
......
Awaken the Overlord, fuse with Yubel, and form a new Yinxiong deck.
When a brand new Yuki Judai appeared in the duel world.
Everything is different.
Yuki Judai: In this life, I will no longer be a lone hero, but will make the whole world tremble—
The ultimate 'Yin Xiong'!
