Doris is surrounded by a variety of friends, including her kind roommate Tsubasa Ginno; however, Doris also has an embarrassing secret: though she can transform into a Panzer - an armor-wearing, fighting powerhouse - her costume leaves little to be desired... because of the giant drill bit on the top of her head!
