Akira (Mako Komaki) was helped by Tetsuko (Moe Amatsuka), a user of “Hadakaken”, who was attacked by the vigilantism. She tries to learn “Hadaka Fist” to help her captive boyfriend, but it is a fist method that causes the other party to die by sexual intercourse. Using “Hadakaken” means losing her virginity. Should I protect my boyfriend (loved one) or virgin (virgin)? What is the too sad conclusion of the maiden who is shaken by the conflict?
