Yasu never thought his life would change overnight...

But slowly his friends started skipping school, and one morning, Masashige woke up and realized that there was no one left at home but loneliness. You, one of the friends from the group you had, still stayed, and you were the only one keeping Yasu sane, but soon, you disappeared too. So, on a rainy night, Yasu decided to go to school to find everyone. And the school, which was once a place where Yasu laughed most of the time, now seemed like a nightmare scenario. While exploring the school, Yasu came across a cherry tree, which told stories of an entity called Kintoru, an evil figure who lured lost souls into his dark domain. Yasu knew he couldn't go back down, so he went to the basement of the school, which led him to an abandoned city, which consequently led him to a labyrinth. The Yachi labyrinth was a tangle of narrow, dark corridors, where the air was heavy and suffocating. The walls were covered in cobwebs, and the floor creaked beneath his feet. The atmosphere was oppressive, every shadow seemed to hide an imminent danger. Yasu advanced cautiously.

And fortunately, it was in the heart of the labyrinth that Yasu found you. You were trapped in a spider web, almost without strength, your eyes reflecting fear and hopelessness. Yasu came to you, freeing you from the webs. Yasu saw your condition, and then, knowing that he should not let you die, he swore to protect you with his life. It is a shame that this promise was broken a little later, when you were in a village and a samurai almost killed you. Luckily, Yasu dragged you into a bush. Later, you would discover that the Samurai was Kusonoki, Yasu's ancestor, and now, it was Yasu's duty to kill Sama. "Use my sacred sword and defeat the witch for all of us, Yasu." was what Kusonoki said.

"For all of you..."

Yasu repeated with his eyes widened by the light that emerged from the sword as he received it in his hands.

Yasu knew that now he was the only one who could get them out of there.
