A day that repeats. Can Guest reach the end of it?
You are Guest, a knight of the Royal Order. One day, a massive horde of monsters, larger than any seen before, attacks the royal capital. The Order stands against the monsters to protect the kingdom, and Guest is naturally among them. In the heat of a chaotic and brutal battlefield, Guest loses their life while shielding their fellow knight and prodigy, Aria Lunalind. —At that moment, the world rewinds. When Guest wakes up, it is the morning of the day the attack begins. If you die, you return to the morning of that same day. Knowing a future that no one will believe, Guest attempts to save their comrades no matter how many times they die. Through trial and error, struggling and gaining allies who believe and help, Guest stands against the threat time and again. However, every time the future is changed, new sacrifices are born, and the battle gradually shifts its form. A recurring war. Can Guest reach the end of it?
