## Plot

10-year-old Kenichi Mitsuba is an average kid who goes to elementary school and struggles with his studies. He is very stubborn and lazy, therefore always ending up frustrating his parents and teachers. He loves to find an easy way out of everything much to the annoyance of Hattori.
Meanwhile, a young ninja named Kanzo Hattori becomes best friends with Kenichi. Hattori becomes a part of the Mitsuba family along with his brother, Shinzo and his ninja dog, Shishimaru. Hattori helps Kenichi with his problems, constantly keeping an eye on him as a good friend. Yumeko is portrayed as Kenichi's love interest.
The main antagonists are Kemumaki, a Koga Ninja, and his ninja-cat, Kagechiyo. Kemaki always causes trouble for Kenichi and Hattori, sometimes inventing new devices to fight against Hattori but always ending up in mishap. Kenichi asking Hattori to take revenge is a recurring storyline present throughout many episodes. Although Hattori is a good friend, Kenichi sometimes fights with him due to misunderstandings created by Kemumaki. Sometimes Jippou, Togejirou and Tsubame help him.
There are five main locations in the series: Tokyo City, Shinto Temple, Iga Province, Iga Mountains, and Kōga Valley.
