Story Of Ninja Hattori
10-year old Kenichi Mitsuba is an average kid who goes to elementary school and struggles with his studies. Meanwhile a little ninja named Hattori Kanzo befriends Ken'ichi. Hattori is now a part of the Mitsuba family along with his brother Shinzo, and his ninja dog, Shishi-Maru. Hattori helps Ken'ichi with his problems, and constantly keeps an eye on him, as a good friend. Yumeko-chan is Ken'ichi's girlfriend. Kemumaki, a Koga Ninja and his ninja cat Kagekiyo (called Amara and Kiyo respectively in the Indian versions) always trouble Ken'ichi. Ken'ichi asks Hattori to take revenge. Although Hattori is a good friend, Ken'ichi sometimes fights with Hattori due to misunderstandings created by Kemumaki.
