I Became a Legend After My 10 Year-Long Last Stand

Luck, Goran, and Eric travel through a dimensional rift to defeat the Demon King. While they are able to badly injure him, they are unable to finish him off. After taking a break, they realize that they are facing what appears to be an insurmountable number of demons. Luck tells the others to leave it to him and return to their families, who are waiting for them. Reluctantly, Eric and Goran turn back while Luck holds off the demon horde.

Luck couldn't tell whether he had been fighting for weeks or months, but the Demon King eventually returns at full power. Since Luck had been fighting demons nonstop, even in his sleep, the number of skills he had learned allowed him to defeat the Demon King single-handedly.

When Luck finally returns to the Capital, he notices several changes, including a giant statue that was erected in town while he was gone. He asks a citizen who the statue is supposed to represent, and the citizen tells him that it is the great sage and saint, Luck, who saved the world ten years ago.

After learning about the statue, Luck decides to go to the Adventurers Guild, where he plans to start over from scratch. There, he reunites with Goran, who has become the Grand Master of the Adventurers Guild. Eric arrives soon after, having been appointed king in honor of his deeds and his role in helping defeat the Demon King. Together, they help Luck hide his identity as the S-Rank Mage Luck and become the F-Rank Warrior Lock. But will Luck be able to hide his true identity forever?

I Became a Legend After My 10-Year-Long Last Stand was really good. It had a similar feel to I've Been Killing Slimes for 300 Years and Maxed Out My Level, as well as The Dark History of the Reincarnated Villainess. While the anime has a lot of familiar tropes, such as adventuring, forming friendships that eventually feel like family, and being a former member of the Hero's Party, it still feels very unique compared to other fantasy anime.

There is a little swearing here and there, but the language is mostly clean. The characters generally dress modestly, with a few exceptions. There is a scene where you see Cellis at the river with her legs exposed, a bath scene featuring Celliss and Sia, and a vampire who shows cleavage during a fight. If you enjoy fantasy anime, I would definitely suggest giving this one a try.
