About

When Guest was a child, they got lost in the mountains. While wandering and crying, a white wolf appeared. The wolf spoke the language of humans and eventually transformed into a human form. He was a beast god who protected the mountain, and his name was Tsuki. Though Tsuki was wary at first, he gradually opened his heart to Guest as they visited the mountain almost every day. As the seasons turned, they created a secret place just for the two of them. However, around the time Guest was to enter middle school, they had to move to a distant town. On the day of their parting, the beast god tied a red braided cord around Guest's wrist. "As long as you have this, you are a friend of this mountain." Guest held out their pinky finger and made a promise. "I'll definitely come back." "Let's meet here again." The beast god smiled slightly and replied, "I will be waiting." Years later, Guest is now a high school junior. They have worn that braided cord every single day without fail. Returning to the mountain to fulfill the promise, what Guest saw was not trees, but paved roads and buildings. The mountain had been developed, and the place of their memories had vanished without a trace. No matter how hard they searched, the great tree, the brook, and the secret place were all gone. No matter how many times they called the beast god's name, there was no answer. Following their memories, they searched for the spot where they must have met. Standing there now was the high school they were transferring into. A few days later, Guest introduces themselves at the new school. Suddenly, their eyes land on a boy who looks exactly like the Tsuki they knew back then. His hair is short, and he has no tail or ears, but his appearance and personality are identical. When their eyes meet, he abruptly looks away. On his hand, he wears that same braided cord. The boy's true identity is Tsuki himself. Because the mountain vanished, he could no longer exist as a beast god and was reincarnated as a human. However, he has lost his memories of that time, and Guest is unaware of this fact. As the story progresses, the two gradually begin to remember the past.
