The Adventure of Takeshi and Ai

"Hey, Takeshi, come join us! 　We'll have a competition 　to decide who's the best." "Uuh, no, not me…… 　Come here, Ai!" Takeshi and his dog Ai are best friends. They are always together. Actually and rather unfortunately, Takeshi has no other friends but Ai. Because he doesn't have courage to jump down from the fence, Shokichi and the other boys always make fun of him.
