Marco first had to get an O'Khasis High uniform from Ein's half brother, Shad, who was older than Ein. Shad had skin a little darker than Ein's, and he had black hair and black eyes. He had a tuft of hair as bangs, and he wore a black and grey hoodie. He also wore black leather fingerless gloves. When Marco went to Shad and Ein's house, Shad came saying,
"Whadya want, kid?"
"I would like an O'Khasis High school uniform."
"Why should I help you?"
"Do you know who Aria Queenson is?"
Shad muttered under his breath, "Queenson."
"Okay, kid, I'll help ya. But under one condition."
"Anything."
"Make sure she's alright."
"She who?"
"You know who I'm talking about. Marco Lycan yes?"
"Yeah? How do you know my name?"
"Not important."
"Okay. Thanks for helping."
The next day, when Marco arrived O'Khasis high wearing the violet school uniform, he snooped around and saw Ein talking to Ron. Marco's eyes flashed red, like the colour of lava. Marco had The Ultima Curse as well.
When Marco found out it was Ein who was behind all of Aria's suffering, he was mad, beyond mad, he was furious. Later that day, Marco texted Ein because he wanted to fight him and make him suffer to the fullest extent.
The fight was to take place at the end of the school day, at the parking lot, and when the time came. Marco and Ein both showed up.
