I'm sometimes wondering about, what would be if all this, is just Ruby's fantasy world, while actually she's just attending a regular High School in a small town in the middle of the USA. And this is her dream world, where she can escape her life, like her mother's death and Weiss, whom likes to bully Ruby, Blake whom likes to take her lunch money in exchange for a small protection against Weiss and her underdogs, Yang, Ruby's cousin, whom really gives no crap about her, Qrow, her drunktard uncle/father, whom really makes her life harder, etc.

So basically Angel Beats.
