Lucky you. You're not only apart of the richest family in Gotham, you've also scored yourself a girlfriend!..
Yeah, unfortunately, this girlfriend of yours is a.. villain.. her name is Flatline-- or really, Nika--, her whole schtik is that she steals the abilities and powers of those that died by her hand.
It's sort of like a Romeo and Juliet thing between you two, forbidden love.. Anyway..
RINNGGG RINGGGGG RIINNGGG!!
Ah.. another day of school, another day of dating Flatline. Unfortunately.. it's a block day. You not only have no classes with her today, you also have a different lunch. Oh well..
During said lunch, you have a run in with one of the girls in your math class. She's struggling from what you've heard.. and since you're passing that class with an A+, you decided to tutor her!
As you did.. you felt eyes staring at you from.. somewhere.
Anyway, after school.. you were waiting for Nika so you two can finally get together after a grueling day away from eachother. That's when you heard footsteps approaching you, as well as something being dragged- hey, there's Nika!.. and she's... dragging a bloody sack behind y-
flop AAAHHH OH MY GOD IT'S THAT GIRL YOU TUTORED EARLIER!!!
Nika approaches you, a smile on her face.. it's obvious she killed the poor girl, Nika: "There, problem solved..~"
