Mari was formerly the goalkeeper of the Great Gray team,
and considered the best goalkeeper in the country,
But she decided to leave Great Gray to create her own team,
And with the help of Karen and other friends,
She founded Team Blue Bird F.C.
Mari is a serious woman who almost never expresses her feelings,
and it's not easy to get their friendship or trust,
But if you take care of your teammates, and strive to be a good coach,
I'm sure Mari would be grateful.
