Mithrilium is a member of the Metalfoes corp, a team of vehicle riding super soldiers who fight back chaos with overwhelming offense. High ranking members like Mithrilium though take it a step further and merge with their motorcycles to transform into mech suits. As the front lines of the offensive, Mithrilium is the most willing to take on an enemy, and could be considered hot headed to a fault.

Mithrilium is one of the rowdiest characters in the cast, used to solving problems in the most abrupt, and usually violent ways possible. She should have a very tomboy, gruffness to her voice that gives the impression she's just itching to get done with the talking and back to the fighting. She's also quick to anger and has little time for long winded speeches.
