Haré+Guu: Movie Special - The Illusive Pilot Film

After the events in the city, Haré and family come back to the Jungle. But it is never calm for Haré as he first must deal with an unstable substitute teacher, then with some big news: Weda is pregnant. The answer to how and who will change his family forever. Poor Haré, now has to deal with a father in addition to his drunk mother and Guu, and soon a sibling too.

An animated pilot film for Ninja Bugei-chou released to the public over three decades later on Ninpuu Kamui Gaiden DVD volume 7. The pilot film was created in 1969 as director Nagisa Ooshima was wanting to make a TV animation to build off his controversial film from 1967. The pilot was rejected by Shirato himself (the original comic creator the film was based on) and the plan was changed to animate Ninpuu Kamui Gaiden instead, a side story to the Kamui Den manga also created by Shirato. Though with this change, Ooshima did not partake in Ninpuu Kamui Gaiden's production.

Haré was a happy boy living out his days in the jungle with his mother, but then one day Guu showed up and became a member of their household. Throughout the series he faces many hardships as he tries to keep Guu out of trouble in the jungle.

Haré's family receives a video letter from Weda's home in the city. Witnessing how sad and lonely Weda's mother and Bel are without her, Weda decides to take Haré and Guu back to the city for a while. After Haré complains about being bored and lonely without his friends in the jungle (as part of his plot to persuade his mother to take him back), Weda decides to send him to a private school in the city, where he instanly falls in love with a pretty girl named Rita. But, of course, Guu wants part of the action too.
