Marko Sakota 
A secluded yet overdramatic high schooler, who unknowingly carries a magic key necklace.
Story
Marko's childhood is a bit of a mystery.
In middle school, he moved away from Limestone to live with his aunts.
Years later, his grandmother passed away. A few weeks before, she had given Marko a “family heirloom”, a glittering key necklace. Strange things began happening to Marko soon after he inherited it.
One fateful day, just months after inheriting the key, he was reunited with his childhood best friend-turned enemy, Adrian. Everything unfolded, his reputation began to deteriorate, and his relationships go down the drain as his friends turned against him.
In an attempt to get rid of the necklace, thinking it may be the source of his misfortunate, he gets himself and the rest of the group stuck in a different time with seemingly no way back.
Relationships
Violet ~ Best Friend
Despite her teasing and odd rants, Marko appreciates Violet's company. He just wished that she'd put in an effort to befriend Elijah as well.
In these trying times, Marko's just glad that somebody will stay by his side.
Chase ~ ???
Marko initially liked Chase.
She started acting more hostile towards Marko when she decided to side with Adrian in their conflict.
Adrian ~ Arch Nemesis
Marko was relieved to leave Limestone behind for many reasons, one of those reasons being Adrian. It's safe to say he's not so thrilled to see his old "friend" again.
Elijah ~ ...Friend??
He and Elijah were friends. They had met a few months prior to Adrian's arrival, and bonded over their shared appreciation for crappy j-metal. That was, until, Elijah learned that the crazy ex-friend Adrian spoke of was, in fact, Marko.
