Itsuki Yuge is summoned to another magical world called Granbania which is on the verge of destruction due to the crisis created by Kegare (Stains) which are due to Hoshi no Midare (The Unrest of the Stars). However, the only beings able to destroy the Kegare are Hoshi no Ko (Children of the Stars) who are Miko.

“Where… is this…?”
Once he opens his eyes, Kirito realizes that he has done a full dive into a fantasy-looking virtual world. While he is uncertain about his memories that he had right before he logged in, he begins to roam about looking for a clue.

Finally arriving at the base of a massive black tree called Gigas Cedar, Kirito meets one single young boy. “I’m Eugeo. Nice to meet you Kirito.” Even though this boy is an NPC within this fantasy world, he has the same range and depth of emotions that humans have.

While deepening his friendship with Eugeo, Kirito is searching for a way to logout of this world. All the while, a certain memory begins to slowly return from the depths of his mind. That memory is of Kirito and Eugeo during their childhood, running about hills and fields––––the problem is that this is not a memory that originally existed. Furthermore, in that memory, there was the figure of a young girl with blonde hair together with Kirito and Eugeo.

Her name is Alice.

Her name is something that he must remember at all costs––
