Armor: Mesta of Tuesday
Woo (full name, William Will Woo) is a member of the Original Seven and heir to a noble family. He appears cold and collected on the outside, but is filled with rage and turmoil on the inside. Woo suffered from the Oedipus complex, or he regarded his father as an adversary and competitor for the exclusive love of his mother. When Woo was an adolescent, he attacked his father with a knife in an attempt to kill him, but his mother jumped in the way and took the hit instead and was killed. After that, Woo left the township his family had governed due to the painful memories, and left it to succumb to decay. Woo has become increasingly mentally unstable since then and seeks to unleash his pent-up rage in any way he can.
