Judo Boy

He's only a teenager, but Kurenai Shinkurou is already both a master of an arcane martial art and an experienced professional mediator with a long track record of resolving disputes. Not bad for someone who's just sixteen and still in school, but everyone has their limits and Kurenai may have met his when his boss and role model, Benika, responds to his request for a more challenging assignment by giving him the task of protecting young Murasaki Kuhoin. Never mind that she's only seven, the fact that the people Kurenai's supposed to protect her from are her own very rich and extremely powerful family is guaranteed to take this job into the danger zone. Now the heat is on and Kurenai's scrambling to put out as many fires as he can, even as the secrets surrounding his young charge bring everything else to a flashpoint.

In the year 1882, Sanshirou comes to Tokyo seeking for a worthy martial arts teacher. There, he meets Yano - a judo master who single-handedly defeats 39 jujitsu practitioners. Extremely impressed by his skill, Sanshirou decides to become his disciple. Later, Sanshirou falls for Sayo Murai - a girl whose father is a martial arts instructor at the local police department; and he also has to face Higaki Gennosuke, a skilled jujitsu fighter and his greatest rival.

It's a pretty basic story about a boy practicing the arts of ninjutsu, fighting evil and trying to find his mother. Young Fujimaru got snatched away from his mother by an eagle and was rescued by a ninja named Sasuke who raised him and taught him ninja techniques. Later Fujimaru embarks on a quest to find his mother, encounters his arch enemy and learns about a secret book that contains secret ninja arts. The series is pretty old, but portraits loads of classic ninja techniques, like elemental manipulation (fire & wind), creating illusionary clones and breathing through a reed.
