Rin Taro’s animation films often recount opportunistic stories. The scenes of destruction presented dramatically in the films are likely to make the audience unaware how his opportunistic stories develop. Opportunism builds on psychological dependence. In his films, protagonists amidst troubles or accidents are helped by not only people but also machines that he has just encountered. In his later career, however, Rin Taro comes to depict destructive aspects of psychological dependence; characters sometimes form a symbiotic relationship with a stranger or a machine, only to go to ruin. Weary of dealing with psychological dependence on the basis of which the protagonist overcomes a crisis, Rin Taro proceeds towards depicting an unusual dependent relationship or his refusal of it.
