Mika Shidou is the militant and straight-forward elder sister of Ken and the knowing member of the Flame Tribe. Having helped Professor Horiguchi with his research, she was the first Sazer to be awakened. At first, she didn't want Ken to see her transform, probably because she didn't want him to associate her with bad feelings that enemies bring. Her cool and reserved attitude often clashes with the bright personality of Tenma, but when push comes to shove she proves to be a true friend. With her Knuckle Riser, Mika transforms into Sazer Mithras, the flame warrior under the sign of Aries, with a white and red armor shaped after a Swan.
