The Secret of the Zigomar Forest (1x4)

Air date: Jan 31, 1988

Takashi and the other four are summoned by Shinotsuka-sensei again after school. So they force Kaori alone to clean the U-Boat, the hideout of the Detective Group. Kaori comes to the hideout even though she is not satisfied with the situation. Then, she receives a fax from Zigomar. It must be a letter of challenge from Zigomar with the words "Morinomegami of the Netherlands" written on it!
