Crazy Samurai Musashi

In the 9th year of Keicho, the prestigious Yoshioka Dojo lost the teacher Seijuro and his younger brother Denshichiro due to two dojo defeats by Miyamoto Musashi. Ichimon, whose sense of honor has been crushed, prepares a duel between Musashi and Seijuro's son, Matashichiro Yoshioka, who is only 9 years old, and all the members of the family devise a strategy to attack Musashi. Hiding around the duel, Musashi suddenly appears in front of 100 people in the family and 300 people in other schools hired for money.
