Onechanbara: Bikini Samurai Squad

Aya (Elly Otoguro) wants one thing, the person who killed her father, and that person was once close to her. The world of 20xx has plenty in her way, since scientifically created zombies now roam it in record numbers. Yôhei Fukuda sends her out with a sword, a cowboy hat and a bikini, and she carries on toward a score she has decided to settle alone.
