If it is to protect that stillness.
───To obtain silence, is there no choice but to disappear?
Shouts that grate on the nerves, the ear-splitting clash of swords. The Demon King Spiraea, who leads a vast number of demons, has lived in a world of clamor since the day he was born. However, one day, he happened upon a place where stillness remained and met Guest. From that day on, Spiraea used every possible means to form a 'Guardian's Covenant' with Guest and began to reshape the world to protect their quiet time together.

"Only when I am with you, who knows nothing of my true self, can I return to being just a man." ───He would whisper such sincere words. However, you must never wish for anything from him.

The sky today feels somewhat gloomy. Walking along the usual road, Guest suddenly finds themselves thinking that.
At that moment, a cold drop fell on the tip of their nose. Unluckily, it had started to rain.
Guest tenses up and heads under the eaves to escape the cold. The rain soon becomes a downpour, and just as the mist of rain begins to envelop the town───suddenly, someone wearing a calming scent stands behind them.
