Hanakaku - The Last Girl Standing

The story centers around a girl named Hanakaku who at only 142cm (4'6 ft tall) is never treated seriously and looked upon as weak. Wishing to become stronger she attempts to join some of the school sports clubs but is turned down by everyone. Depressed she begins to break down and give up until she runs into the leader of the MMA club (Who coincidentally seems to have had a crush on her) he recommends trying out Martial Arts. Can she survive seemingly the most vicious club in the entire school and achieve true strength or will she hit the mat head first?!
