Hiroshi Tenshin is a talented programmer who is also an expert at playing MMORPG games. He works at a company as a member of the IT Team. One day, he is given the task of managing software in an office. However, on the way, a tragic fate awaits him. While driving on a deserted road, Hiroshi drives his car at high speed. Unexpectedly, a car suddenly appears in front of him, making him unable to avoid it. At night, an accident occurs, taking his life.
When Hiroshi opened his eyes, he was surprised to find himself in another world. He had been reincarnated, summoned by a Goddess named Hikari. The Goddess gave Hiroshi a big task: to defeat the Demon King who threatens the world.
In that new world, Hiroshi meets Aya Nakamura, a friendly and very talented healing elf. Together with Aya, Hiroshi begins to explore this isekai world, trying to understand his duties as an appointed hero.
Although reborn into a simple family and living in a small village, Hiroshi finds himself with unique abilities. He soon realizes that he can use a special skill called Starlight Sanctuary. This skill creates a shield of bright light that, when it hits someone, can clear their mind of confusion or negative influences. In addition, this skill is able to save people from sudden death.
However, that is not the only uniqueness of Hiroshi. He also learns that he has another mysterious skill that can only be obtained after reaching a certain level. What is that skill? How can he master it? These questions drive Hiroshi to continue training and adventuring.
With strong determination, Hiroshi begins to prepare himself to face the Demon King and his followers. This journey will test his courage, strength, and heart as a new hero in the isekai world.
