Masamune Makabe (voiced by Natsuki Hanae) was a fat boy when he was young. He was nicknamed "Pig's Feet" by his classmates and lived in inferiority and ridicule all day long. Later, Masamune transferred to another school and received eight years of training. He finally regained his normal figure and unexpectedly discovered that he actually had a handsome face. Now, Masamune has returned to the city where he once lived. He is full of anger and has formulated a series of revenge plans, vowing to let the girl who gave him the nickname, Adachi Aiki (voiced by Ayaka Ohashi), experience the humiliation he once experienced.
