The Samurai  

Za Samurai, ザ・サムライ

Takeshi Chimatsuri is a sixteen-year-old high school student who has devoted his life to becoming a skilled samurai like his father was. One day, two ninja sisters named the Toki twins transfer to his school and challenge him to take back their family dagger from him. However, they have discovered Takeshi's weakness: his fear of the naked female body. To overcome this fear, he must undergo special training from his classmates Atsuko and Torai, as well as his teacher Miss Ayatsugi. The Toki twins are constantly fighting with each other, making it difficult for Takeshi to focus on his training.
