: Yumeria Moegi is a 23-year-old woman who loves cosplaying. Her name used here is a cosplay alias instead of her real name, Yuko Yamada. Though she acts like a child and might look younger, she is actually an office worker during the day and speaks in a deep voice whenever her costume's look is compromised. She is also known to draw her own doujin manga and tries to sell them at Comiket, which she often babbles about during her roll call as Akiba Yellow. In Season Two, the "pigtails" on Akiba Yellow's helmet becomes an "odango-style double bun" with a ribbon on them. She married into the wealthy Yokoyama family and now goes by the name Yuko Yokoyama, rather than by her cosplay nickname. Though her new family upbringing initially restricts her otaku tendencies, she secretly keeps her manga collection behind the bookshelf in her bedroom.
