Class 3-E Starts in Konoha

After transmigrating to the Naruto world, Koro-sensei became an "ordinary" genin of the Hidden Leaf Village.

He was the Yellow Flash of the Hidden Leaf, the twin of the Eight-Tails, Jiraiya's most devoted fan and reader, and the widely acclaimed Sixth Hokage.

Great Toad Sage: "He changed the shinobi world."

Kurenai Yuhi: "You're so kind. It would be a shame if you didn't become a teacher."

Gaara: "Thank you, dark-circled uncle, for giving me a new family!"

Onoki: "Stop trying to abduct my granddaughter!"

Uchiha Madara: "When it comes to speed, I, Madara, consider you the strongest!"

Black Zetsu: "Mom, this octopus is bullying me!"

All the people of the Five Great Nations: "A birthday cake for the Sixth Hokage's inauguration!!!"
