Ebisu

specializes in the private training of elite ninja, as stated by Kakashi Hatake. The name "Ebisu" comes from the Japanese god Ebisu, who is usually pictured as a fisherman that brings wealth and prosperity to believers, and watches over the health of young children.

Personality
Ebisu is portrayed as a stern and by-the-book type of person. Initially, he believes that only people of high lineage can amount to anything, but upon seeing what Naruto has done for the village his perspective changed drastically. While rather uptight, he has shown a true dedication to his village and students.

Also, although he tries to be very professional, he has displayed some perverted traits, as shown from how he reacts to Naruto sexual-oriented tactics. He has been described by Naruto as a "closet-pervert".

Abilities
Ebisu, being an elite trainer, has extensive knowledge in basic to advanced forms of ninja skills. According to Kakashi, Ebisu is one of the most skilled trainers in Konoha, further emphasized from the fact that he was personally selected to train Konohamaru for the academy and chosen by Kakashi to train Naruto for the Chunin Exams. While he has not been seen much in battle, he has demonstrated proficient skill in high level ninjutsu.

Konohamaru arc
He is first introduced as Konohamaru's tutor, and dislikes the fact that Konohamaru idolizes Naruto Uzumaki, because he only sees Naruto as the container of the Nine-Tailed Demon Fox. His opinion of Naruto doesn't change when Naruto "defeats" him with the Harem Technique after the Sexy Technique fails. Naruto often refers to him as the "super/closet pervert" because of this.

Chunin Exams
Later, recommended by Kakashi Hatake as a great teacher, Ebisu begins Naruto's one-month training for the main matches of the Chunin Exam. It is during this time that through being with Naruto and seeing the influence he had on Konohamaru that Ebisu realizes that Naruto is not just the container of a demon, but that he is an outstanding Konoha ninja. However, Ebisu does not complete Naruto's training, because Jiraiya takes over by summoning Gama which tongue-whips Ebisu unconscious when Ebisu tries to interrupt Jiraiya's peeking on a women's bath. Naruto then insists that Jiraiya take Ebisu's place.

Rescue Gaara arc
In Part II, he has been put in charge of a Genin team with Konohamaru and his two friends, Udon and Moegi, as its members. He now wears the standard flack jacket instead of his more casual outfit from the first part of the series. He is introduced when the team have just finished their mission and is receiving payment. There he tries to stop Konohamaru in complaining about the low rank of their missions and tries to apologize to Tsunade for his student's behavior.

Fire Temple Filler arc
In the Fire Temple Filler arc, Ebisu assigns Team Ebisu their first A-rank mission to escort the people to safety and is shown assisting the Konoha ninja against the zombie ninja.

Invasion of Pain arc
In the Invasion of Pain arc, after Konohamaru witnesses Pain killing two Konoha ninja and gets noticed, Ebisu appears to try and buy Konohamaru some time to escape, and after thinking of all Naruto has done for the village, refuses to give his location to the Akatsuki. He was about to be killed until Konohamaru throws a kunai at Pain and saves him. Ebisu then watches in amazement at not only how much better his student does at battling Pain, but even more so that Konohamaru could use the Rasengan.

Trivia

 * When looking both at manga and anime (Part II), one can see that Ebisu is only using his middle finger to push up his glasses. In the anime (Part I), this was removed. For Part II, it wasn't removed for some apparent reason.
