Majutsu wo Kiwamete Tabi ni Deta Tensei Elf, Moteamashita Jumyou de Ikeru Densetsu to Naru - Episode 24

Minoru Kido, age 30, cause of death: traffic accident. As a Japanese, I died without leaving any evidence of my life. At the time of my death, I was thinking, "Next time, I want to live a long life and leave behind some proof of my life," when I was reincarnated as an elf with a life span of 1,000 years! That's why I made a vow. I vowed that this time I would spend my whole life living in a way that would leave a mark on my life. At the age of 20, I was able to use all of the healing magic that elves were originally equipped with at will. By the age of 30, I had mastered all attribute magic, and by the age of 100, I had deciphered all the ancient magic formulas. For the remaining 900 years of my life, all I have to do is run out of the Elven forest and become a warrior. One day, I'll be missed by a fledgling adventurer who will eventually be called a hero. Sometimes, a country is founded in my name. Sometimes, I was called the founder of magic and became an object of worship. This is the story of a reincarnated elf who roars his name into history as a living legend. (Source: Kakuyomu, translated)
