Seria, a young girl living at her aunt's house in New York, received an unsigned email and embarked on the road to study in Gotham without hesitation. But the life in Gotham seemed to be more different than what she remembered. For example, she didn't remember that there used to be a strange guy in Gotham who would wear a red hood and a leather jacket and ride a motorcycle around the streets.
When Seria had her skirt stained by the biker's tires for the third time, she was wondering why this guy hadn't been caught by Batman yet.
When Seria crashed the scene of the suspected affair between the motorcycle man and Batman, she thought that this guy got into power through a belt relationship.
Batman: He's a very important person to me.
Motorcycle Man: But not the most important thing.
Ceria passing by: Wow.
