Hikari Mitsushima is definitely a stand-out in this film aside of course from Takahiro Nishijima who portrays Honda, the lead star.  Mitsushima as Yoko has that no-nonsense stance and doesn't see her gender as a weakness but in fact as a sign of superiority,  even resorting to violence to hurt men.  How and why these lead  characters click is for you to find out but definitely there's a touch of LGBT  genre in this film, owing to the character of Koike.  Disturbing,  weirdly comedic and  enthralling all at the same time.
