Master of Martial Hearts (Blu-ray)

When schoolgirl Aya stumbles on a nasty, throw-down street fight between a shrine priestess and a flight attendant, she can't help but get involved... and soon she finds herself an unwitting player in a clandestine martial arts tournament. Pitted against everyone from a bikini-clad cop to her very own science teacher, Aya soon realizes that the battle has more at stake than the Martial Heart - a jewel with the power to grant wishes. No, something far more sinister will reveal itself, along with a shock ending that'll leave your jaw on the floor.
