I wonder what this key is for...? And why in the hell did Saiou GIVE it to me when he's now sending Asuka after me to get it back, claiming Edo and I stole them.

As for Asuka, I really can't believe she's just dueling how Saiou told her too and not even with her own deck, it's kinda....dull.
Asuka! I'm gonna light a fire in your heart and bring back the Asuka we all know!!
