Elf no Shugosha

The Silver Darkness brings about the awakening of the Guardian of the Elves… that’s a saying passed down for generations in the elven society, but at least for Yuuto, he only remembers his name and the phrase “Guardian of the Elves” as he wakes up in an unknown forest being carried by people who he doesn’t know. His lack of memory will be the least of his problems as a large army from the Thousand Empire invade the forest, but he’s luckily saved by a group of elves who repel the fiends. He meets a beautiful elf named Siris who decides to take him in as a hostage, but finds out that he has the seeds to the World Tree, which bewilders everyone at the Elven camp. That night, however, the same army invades the Elven Camp, and completely outnumbered, Yuuto steps in and offers to surrender in exchanging for no one being killed. While enraged at Yuuto’s actions, the chief of the camp decide to place Yuuto in charge of their town as he knew about the “Guardian of the Elves”, and Yuuto agrees to assist Siris in any way he can to restore the former glory that the elves once held.
