Episode 87: どうするユウディアス – Dō Suru Yūdiasu
(What Will You Do, Yudias?)
It seems there’s a reason why Kuaidul can’t turn Yudias into a card. There’s a powerful lock on Yudias’s mind, which prevents him from realizing the truth about the Kuaidul Spacetime. In order to remove this lock, the “Make Yudias Realize!” Operation is put into action! What will you do, Yudias?
