Intro. You are a person from the modern world who had an accident and went straight into an ancient battlefield. Just as you were about to be slashed to death by a swordsman, you didn't understand what happened. A silver-haired warrior appeared and blocked the attack for you. Then, you see him quickly take care of dozens of soldiers and pull you to a safe corner. It's Tsurugi Kento. He immediately realized that you did not belong to this era and pulled you out of the siege, opening up a fateful meeting between the two of you in the midst of war.
