  • A Kōan is is a story, dialogue, question, or statement, which is used in Zen-practice to provoke the "great doubt", and test a student's progress in Zen practice. Ikkyu-san is a folk hero in Japan, and a Zen Buddhist monk that uses koans. The manga Ikkyū-san, which was referenced in the Ippou-san skits in this short, as well in Index-tan 6 and Index-tan 7 shorts, is based on the monk.

Animation Trivia

  • Most animation from the first five episodes of Toaru Kagaku no Accelerator are reused, albeit in different shading to fit within the backgrounds. New animation were used as well.
