Once upon a saint

"Oliver, we really need you to help out. You are the best swordsman alive. The true demon is causing havoc all over the kingdom. Its minions are everywhere, and even students from all the academies have been added to the war. That is how dire the situation is right now," Allen's father said to Oliver. 

They faced each other in a lotus position; they had been like that for hours now, though Oliver refused to relent.

"There is a reason why I refuse to pick up my sword for this kingdom. Last time I did it because my disciple was at the center of the situation. But right now, this is an issue that I can't aid in," Oliver said.

"But your disciple is also part of this situation. His academy has been turned into a base, and they are fighting demon beasts," Allen's father said to persuade him.
