Ruhe Xiangan

On the first day, I was pestered by a girl. The next day, they both entered a different world by mistake. "I will definitely be your savior" "Then it's agreed, you have to save my life." Shuhe, who is terminally ill, wishes to find his biological sister, and the woman is convinced that the young man in front of her is the key to realizing her wish. She just looked at it lightly, with a sad look on her face. The monster shadow that climbed up from the depths of the ground followed the man in front of him all the time. "I have to save him first before I can find her." The woman promised Shuhe not to be disturbed by the disease for three months, and even took out a blue scimitar for her to use. "Its name is Kun, and it will be your sword from now on." "What? You want me to plug the hole too." "What? Shadow also wants me to kill him." With the blade in hand, there is no way to retreat. With all my strength, I will slay all the demons and evil spirits until dawn and the wind is gentle and clear. A girl whose duty is to save others + a decadent boy = a fantasy adventure of youth [No CP direction + big heroine + redemption]
