A school girl kneels on her mat looking over an old photo album containing pictures of people committing seppuku. Becoming aroused by what she sees, she touches herself and licks her fingertips. She pulls out a knife of her own, takes off her uniform, and in a very fetishistic manner proceeds to slit open her stomach and then pull out her guts.
A black and white preface shows a woman in a traditional kimono climbing the stairs as WWII era Mitsubishi Zeros fly through the sky and footage of the Japanese military of the era is superimposed over the footage. She stops at the top of the stairs to say her prayers, rings a bell, and heads inside where the footage is shot in color. She unravels her kimono and rubs her face with the cloth before wrapping her blade and lovingly touching it. She pulls it across her stomach and slits herself open, falling to the mat. She crawls across the mat, dying, slipping in her own slick blood until she can't move anymore.
