An internationally renowned fashion designer and boutique owner.
She contributed costume designs to characters in World's Odyssey. Seems like she found more satisfaction in making real clothes than virtual ones, so she returned to her home country after the game took off. She's currently not in Sagami City.

Reality and games aren't so different, you say? Clever, but despite this world's distortion, it still isn't equal to a game. Svetlana Amou likely thinks the same. Her extensive knowledge of the world might be linked to her involvement with Lucil Filarete's design. She's a figure worthy of being called a witch or a sage.

I wonder why Sayaka travels abroad to meet her. Maybe there will be some chaos, even in the development of End to Odyssey. But hey... without drama, it wouldn't be fun, right? In a distant land, she and Sayaka will face off. Why? That's for us to find out.
