An old hermit suddenly came to the house! A slapstick and exciting family gag co-authored by Fujiko F. Fujio and Fujiko Fujio (A)! ! The little old man who suddenly arrived was an ancestor who had been training as a hermit for 100 years! ! A lively old man who uses his imperfect but mysterious "Senjutsu" to amaze the people around him and make a fuss! Please laugh a lot.
