Twins 99 Plot

Twins 99 revolves around 2 black twins named Javon and Jovan Sankoh, whom are massive anime otakus. They're starting their first year in high school in the hopes of a new start after being practically losers in middle school. Out of nowhere during school, a Darkseid looking alien assaults them, abruptly demanding for a relic called the Aquos Crystal. To add more confusion, it is revealed during the attack that these twins have superpowers which they were clueless about their whole lives. Aliens and superpowers exist?!  Is this the new start they're looking for? What's the Aquos Crystal? What will happen in this hysterical, dramatic, action-packed anime carved into a light novel?
