Kirito and Yukina stepped in soon after they heard about the attack by un-dead. They attacked those un-dead using their magic sword and staff. After a few minutes, yukina started to heal the wounds of injured while kirito is purifying the un-dead using holy magic. Everyone was surprised by the power and teamwork they demonstrated. He purified all of them and yukina healed everyone. Finally, the un-dead bone dragon has appeared in front of them. It attacked them but they dodged it. Kirito wasn't able to attack because he lost most of his M.P by purifying those un-dead. Yukina uses a healing spell by kissing him. It transferred her M.P to him. Then, he purified the un-dead dragon. They both fell unconscious due to exhaustion. Knights and mages made arrangement for their treatment. Everyone thanked them for their assistance. Next day, they were summoned by king. He gave a reward of 200 platinum coins and noble rank of 'Baron' to them. He awarded kirito with twin dragon medal which wasn't given to anyone in last 80 years. He became very famous.
