Nintama Rantarō

Nintama Rantarō (忍たま乱太郎) is a Japanese anime series produced by Ajia-do Animation Works and Japanese broadcast on NHK since April 10, 1993. It is an adaptation of the manga series Rakudai Ninja Rantarō, written and illustrated by Sōbe Amako. Nintama Rantarō centers on the title character and his friends as they attend a school for budding ninjas. Like the manga on which it is based, there is a considerable amount of anachronisms for comedic purposes; for example, the titular character Rantarō is bespectacled. The anime also references other Japanese media personalities such as Ken Shimura. The series is currently the longest-running anime on NHK. The official English title is Ninjaboy Rantaro.

In July 2011, a live action film version directed by Takashi Miike titled Ninja Kids!!! was released. A sequel was released on July 6, 2013, called Ninja Kids!!! Summer Mission Impossible! (忍たま乱太郎 夏休み宿題大作戦! の段).

 * Gentle and full of kindness, he is a senpai that lovingly takes care of his underclassmen.

Of the "three illness of the ninja", he is the "type who lacks thought". Also, if he goes near a dry river bed, the moisture will expand his hair. Hachiya Saburou from the same class is often seen borrowing his face, lending them the relation of "fifth-year rogumi's specialty combination". Yamada-sensei often says "his honesty is his weakness", but in the 18th volume he passed the survival orienteering while retaining his playfulness. In that survival orienteering he was paired in a group with Ayakashimaru. In the original work Raizou's hair is black, but in the anime it is a bright brown. His namesake is from a proverb meaning 'to follow others blindly' (付和雷同).
