first ep reminds me of One Piece. Main character has an "interesting" design.

AnimeNFO says :
Based on Kiriyama Koji's manga published on Shonen Jump, this story about the adventures of Ninku ninja clan was brought into animation.

The ninku is a clan of extinct ninjas who command esoteric and powerful techniques, hence a lot of other groups are constantly trying to steal their techniques to take over the country. Their primary target is Fusuke, a weird looking kid but one of the most powerful Ninku ninja. Fusuke, together with other Ninku ninja with different specialties must fight those threat that caused the downfall of the Ninku clan.


Episode 1 by a group called Daichi. The ep is an okay introduction episode. animation is, well 1995 (still remember NGE was 1995). Sound is not very good in this version, and sound effects, while not so good, are still okay. The story I find interesting tho. and the comedy is kinda good too and while the show features a "kid", its still mature enough.


Edit
You can find up to ep 9 Here Thanks bud
