However, we were able to divert there attentions long enough to acquire the tiny file on Michi's where a bouts during the time that we lost contact with her.
It appears that she relocated herself to Baltimore Maryland, where she planned on leaving behind the duties of a hero and hoping to lead a normal life. However, she was again attacked by a mysterious figure with whom she seemed familiar with.
The files do not mention his name, but they do mention that he was the gentleman that cause an Earthquake in Southern Japan while Michi was there and she recieved the blame for it. She seemed to have battled him, nearly losing, when the Protectorate based in Baltimore, jumped to her rescue and, together fought off the mutant, sending him running.
She seemed to have an accordance with the supergroup do to that incident and was soon taken on as an ally shortly after. When the Protectorate opened a branch up here in Paragon City, they asked Michi to join, although she had no experience in the military or training in such an area.
At first they used her as a translator, but she quickly learned her way around the militaristic base and became a well respected member.
