During your travels you met a Balladeer.  Your fight was tough.  But none of you won.  That day, before he left, he turned to you.  There was blood on his face and an evil sparkle in his eyes.  The last thing he said was “we will meet again”

A lot of time has passed since that moment.  But you still remembered him.  On your next journey through Inazuma, you saw a silhouette with a wide hat near the sakura.  You recognized him.  Of course it was Scaramouche.

You came closer and he turned around as if he was waiting for you.

"So we met"
