Best Anime Mentors

In Life, we all need guidance from someone to move forward in the right direction. Someone to make us realize our mistakes. And here a Sensei is all you need.

In anime series too, when the protagonists follow the path guided by their mentor or teacher, they become even more powerful. Without their help, the heroes couldn’t have been what are now and the stories we know today would have been different.

These anime senseis have played a massive role in refining the MC’s life and whose words inspire us all.

So today, we decided to take a look at the top 10 best Anime Sensei of all time. Let’s get on the list!

1. Jiraiya – Naruto & Naruto Shippuden:

Master Jiraiya

Jiraiya’s first appearance was in Naruto (Episode 52 – “Ebisu Returns: Naruto’s Toughest Training Yet!” ) where Jiraiya returns to Konoha after a long time. After this, he trained Naruto in his ways and taught him to control Kurama.

Jiraiya was also a part of the Legendary Sannin and was considered the most powerful shinobis in the whole village.

He is also known as the Toad Sage as he can summon up toads to help him during battles. The Great Toad Sage once told Jiraiya that – he (Jiraiya) will become the teacher of a child who will either destroy or create a new world.

Jiraiya was a mentor to many great shinobis like Minato, the Fourth Hokage, Nagato, Yahiko, Konan, and ultimately Naruto. He taught them all the moves he knew in hopes that someone will become the child of the prophecy. 

The other trait of Jiraiya was that he was a big pervert and used to write ero-books. He would roam around the world and collect information and look for “inspiration” for his books.

When Jiraiya’s teacher, Hiruzen, the Third Hokage dies due to an attack led by Orochimaru, Jiraiya was offered the position to be the Hokage. But he instantly declined the offer as he believed that he does not fit the role and voted for Tsunade to be the Hokage. 

When Naruto was unsuccessful in pursuing Sasuke, Jiraiya took Naruto with him for 2 and a half years and trained him to become stronger so that he can protect himself from the Akatsuki. 

Jiraiya’s wish was to get rid of all the hatred the ninja world had and therefore he passed down all his ideologies to Naruto.

Ultimately, he was the best sensei Naruto could have.

2. Koro-sensei – Assassination Classroom

Best Anime Mentors

Koro sensei’s first appearance was when he became the homeroom teacher for Class 3-E of Kunugigaoka Junior High School. He was a yellow-colored octopus. He claims that he has created the crescent moon and it was a demonstration of his huge power. He threatens all that the next time he would destroy Earth. He was also like the deuteragonist of this anime series.

Koro-sensei is very powerful in terms of strength, speed, and everything. The students in the class were given an option to kill him by any method by the end of the year to get huge rewards. But Koro-sensei was so strong that no methods worked on him. Throughout the whole series, the students plan various ways to kill him but they were of no use.

No one knew why this powerful creature was willing to teach in a school. He taught the students with great passion and cleared all the doubts the students had. He was a very genius and intellectual teacher. Koro-sensei taught his students’ various valuable lessons about the importance of someone and to decide our paths.

At first, the students of this class were outcasted by all the other students as they were just average in their work. But later after Koro-sensei became their teacher, each one became an excellent student as they followed the path they were best on.

3. Silvers Rayleigh – One Piece

Silvers Rayleigh

The first appearance of Rayleigh was in the 400th episode of the Anime (The Pirate King and His Right Hand) when he was held as a captive (by his own choice though) at a slave auction in Sabaody. Later, when Luffy and others first saw him, they were dumbfounded by the immense power he possessed.

Upon further interactions, we came to know that he was the right-hand man of the Pirate King Gol D. Roger, and was a member of the legendary Roger pirates. He was known as the “Dark King” and regarded as one of the most powerful pirates in history. Also, Rayleigh possessed the “Conquerors Haki”, which just makes him more powerful.

 Rayleigh was one of the counted people who knew what ONE PIECE was!!!!

He was one of the main figures since the time of Roger, Whitebeard, Garp, Sengoku, and all but now he was a retired pirate. Now he was living his life by becoming a coating mechanic for ships at Sabaody Archipelago. 

Later, due to some major incidents, he decided to train Luffy and took Luffy with him for 2 years to train him. Luffy learned everything about Haki from Rayleigh. He taught Luffy everything he knew, his signature moves and showed him the ways to become powerful.

4. Satoru Gojo – Jujutsu Kaisen

Satoru Gojo

Jujutsu Kaisen was the most popular anime of 2020 and a major reason for it was due to this man Gojo Satoru.

Gojo is one of the main characters of this story and is considered to be the strongest jujutsu sorcerer alive in the whole world. He is also rival or in some cases a superior to Sukuna, the King of Curses. He even claimed that he could defeat Sukuna in his full power too.

 On one side, he is a free-minded and funny guy but on the other side, he is a freaking hot badass character.

In the first episode, we can see that Sukuna couldn’t do anything against the mighty Gojo. Gojo has various kinds of extraordinary powers which are to be seen in the whole series.

Even the special graded curses felt too powerless against him and they were not arrogant enough to face Gojo Satoru. In the story, we saw Gojo using his infinite void which is just a huge power demonstration from him.

He is a teacher at Jujutsu High which is a school for Jujutsu Sorcerers where they are trained to defeat curses. He taught many powerful students like Yuta (considered as the one to surpass Gojo) and also Itadori (vessel of Sukuna), Nobara, and Megumi. He was also feared by the higher-ups of Jujutsu society.

5. Kakashi Hatake – Naruto

Kakashi Hatake

One of the most coolest and powerful characters of the whole Naruto and Naruto Shippuden series is Kakashi Hatake. His first appearance was in Naruto episode 3: “Sasuke and Sakura: Friends or Foes?”

He was a Jonin and was regarded as an elite ninja and was assigned as the sensei of TEAM 7 which consisted of Naruto Uzumaki, Sasuke Uchiha, and Sakura Haruno.

To become Kakashi’s pupil, one must complete the test given by him. Therefore, no other student before the members of Team 7 became his pupil.

He was a very decisive mentor and taught his students the various ninjutsu and the techniques to perform them.

He never let anyone cause harm to his precious students as he cared for them very much. 

Kakashi possessed the Sharingan in one eye which was considered a powerful weapon of the Uchiha clan. The Sharingan has the ability to detect minute movements and also see through the techniques of others. He is known by the world as “Copy Ninja Kakashi” as he is the only ninja who has copied over a thousand jutsu from others.

He always participates in challenges given by his one and only rival friend, Might Guy. Kakashi believes in the power of teamwork and wants his students to acknowledge it too.

6. Master Roshi – the Dragon Ball series

Master Roshi

Master Roshi, is the man who trained one of the strongest characters of the animeverse- Goku. To Goku, he was not only a teacher but also a grandfather-like figure.

Master Roshi met Goku when he was very small, and he knew the potential of Goku’s strength so he decided to train him to become a great fighter. 

Master Roshi is known as the turtle hermit and had a turtle school of his own. The dress that Goku wears till now- the orange and blue uniform was Turtle school’s uniform.

He trained Goku by various methods like he ordered him to wear a turtle shell which was about a ton weight, he told him to deliver milk to people, move heavy boulders, etc. Master Roshi also trained Krillin, Yamcha but none were as strong as Goku.

The iconic and signature move of Goku- Kamehameha was actually a move he learned from Master Roshi.

One day Master Roshi entered into a tournament under a disguise where Goku was participating and was easily winning. But Master Roshi defeated him to remind him to be not arrogant of his power.

By this, Goku understood that he was not only the strong one; there are lots of other people who are ahead of him. So, from then on he tried his best to be a better fighter. 

7. All Might – My Hero Academia

All Might

In the story of My Hero Academia, All Might is represented as the strongest hero in the world. The no.1 hero. He was a symbol of peace and justice and due to him, Japan became a stable country at his prime stage. He was so powerful that he would overpower Katsuki and Izuki easily even if he is handicapped.

The villains were too frightened of him and were wiped out one by one by him. He was also able to defeat All For One who was considered to be the world’s strongest villain. Although All Might defeated him, he too suffered quite a vital injury from the fight. It limited his power and duration he could use his power. Even with this power limitation, his speed and strength were top-notch.

He was not only the strongest person but also a great teacher for students. He passed down his Quirk to Izuku Midoriya and told him to pass on his legacy. He trained him day and night on how to use the Quirk. For Izuku he was the best teacher one could get.

He trained all of his students very efficiently and with great care. He also protected his precious students from all stronger villains by pushing them to his limits. He continued to push through his limits even though they were damaging his body.

8. Izumi Curtis – Fullmetal Alchemist & Fullmetal Alchemist Brotherhood

 She lives with her husband Sig in the American town- Dublith where they run a butcher shop.

9. Biscuit Krueger – Hunter x Hunter

Biscuit Krueger

Biscuit Krueger has a dual personality. She looks very cute from her outer appearance and due to this trait of her; she can collect information or get any help from anyone easily. But she is a bit different from the inside as she is a strong fighter who doesn’t want anyone to know about this quality of her.

To call her, using an honorific, one must use -Chama (- chan + – sama). She deceived her opponents by her looks and get victory over others. The one thing she doesn’t like it when someone talks about her age. She also doesn’t like to be left out of a conversation. But she melts when someone compliments her and she is easily persuaded by this.

10. Eikichi Onizuka from Great Teacher Onizuka

Eikichi Onizuka

At his first appearance, Onizuka is a very arrogant and ill-natured person who is often involved in troubles. He is a perverted fellow who seems to fail to get in any relationship with a girl. He is rejected by every girl and is a vulgar-natured guy.

His behavior is very eccentric as his methods of teaching are very unique or foolish depending upon the views. He solves all problems epically or weirdly which is just not taken by anyone. He always does the unexpected. He is either a genius or a fool who fails to realize it himself.

At points, he is very serious when the situation calls for it. He always surprises the people around him with his actions, words, and behavior. But Ryuji was not surprised by this as he has known Onizuka for a long time. Also, the principal of the school trust Onizuka very much. 

One day he ordered three Otoro and a Sushi Boat, but he didn’t have enough money to pay, so he ran away from the spot. He was a great eater, especially in the case of Sushi.

When he knows someone’s secret, he would pull pranks on them like on Hajime Fukuroda, he knew that Hajime has a longing for the students of the academy and therefore he hit him with water rockets.
