Shakespeare-Styled Names for Love, Tradegy and Crime!
Yuusaku Amasugi = Romano Telmah. His first name is a parody of Romeo, and his last name is Hamlet backwards.
Mareka Amasugi = Julie Telmah. Her first name is a parody of Juliet, and her last name is Hamlet backwards.
Aiga Hoshiidake = Iago Brutis. A play-on of Shakespeare's two most famous double-crossing backstabbers. Iago from Othello, and Brutis (Brutus) from Julius Ceaser.
Kamen Mask - Ma'sk The'ft. Say it slowly or with a Scottish accent, it sounds like Macbeth.
Kurobee Busujima - Julius Falstaff. Julius was killed by someone he thought was on his side, and Falstaff is one of Shakespeare's dumb characters. In other words, Kurobee was betrayed because he was an idiot. Hehe. >:)

It makes a lot of sense to me, from all the fanfiction I've read. Yuusaku and Mareka are considered to be the best couple, despite their differences. Aiga likes to quote old phrases, is a betrayer but also a touch of poetic justice and dream building to him; instead of Suvari and other old Japanese words, he could speak sometimes in that old English language Shakespeare is (in)famous for.

- "Doth thou speak unto me, sir Wright? I will fight you until my eyelids no longer wag!"
- "Then how about THIS!?"
- "ACK! A touch, a touch, I do confess!"

But at least in this case, Romeo and Juliet live happily ever after.
