Harem of the final villain in an ERO MMO!!! I just need to survive

Keith entered the dungeon alone this time. He wanted to try out his new power and see how it would work out for him.

By the law of fiction and games, Keith should be able to use his power as soon as he had the seal to see the mana. So, he was confident when he used his spell.

He could feel his mana flowing into his spell and he could feel his spell powering up as he wanted it to. He could do it; he could use his spell as he wanted to use it….

But just as Keith was about to celebrate his victory in controlling his mana, it went out of control and Keith ended up putting a lot into it. As a result, his spell blasted a hold of the rock in front of him.

"Shit, I messed up. I could see the amount of mana I was putting out but I could not control it properly."

Out of all the possibilities of failure Keith could have foreseen, he had never expected mana control was not one of them.

'This is not fair. Shouldn't I can cast spells how I want to know that I have this seal on my body? What is with this wacky mana output by my body?'

Keith tried again to cast a spell and he moved his mana. But this time, it ended up being too little and his spell phased out.

The next one was perfect but the mana decided to go out of control halfway through his casting. Keith was getting more and more discouraged by the second.

By the end of two hours, he had only managed to cast a single spell how he wanted to and his back was burning.

"Ah, I should have known it would not be easy to use magic for me. Why did I think things would go my way now that I had an ability? When had things ever been this easy for me?"

Keith lamented his luck as he rested on his chest. He was too tired to move on his own so Keith decided to keep lying down for some time more.

But of course, the dungeon was not even going to give Keith that.

There was a loud yell that was heading Keith's way and the floor of the cave shook with harsh vibrations. It was like a small earthquake that made Keith lose his balance when he tried to stand up.

'This is not good. I am in no condition to fight anything. But maybe I can cast one more spell?'

Keith channeled his concentration on his earring and pulled out the magic. His body was doing things but Keith's mind was heavy with the fog of exhaustion.

The spell hit the monster and it evaporated into the air. The spell had been perfectly cast by him but Keith was too exhausted to notice how his body had taken over for him.

He collapsed on the ground with a mana burnout and his eyes closed. Even if a monster was to come his way, Keith would not notice and keep on sleeping.

But he was lucky since his unconscious body was found by two adventurers who panicked to see him dead. But they soon realized that he was not dead, just asleep.

They pulled him into their camp and waited for Keith to wake up.

He did wake up in about six hours with the smell of food hitting him. His brain was foggy with sleep and hunger so Keith devoured the bowl in front of him with vigor.

"Hey, easy their lad. There is no need for you to eat in such a hurry. No one is taking your food away from you."

Keith did realize that but his body still devoured the food in front of him until he was halfway full. It was only then he noticed the two adventurers looking at him with weird looks on their faces.

He calmed down and tried to appear dignified. His body unconsciously straightened up and his dignified posture came back.

"Man, there is no need for you to be so formal with us. We saved you because we wanted to. There is no need for you to tense up like this."

The female of the group assured Keith and the tension bleed out of his body. He had never noticed how tense being the grandmaster made him be.

For the first time, someone had looked at Keith ad noticed his true feelings. But Keith was sure it was because he was not the grandmaster right now but an ordinary person.

"I'm sorry for my lack of manners. I was just too exhausted and hungry that I forgot everything. Let me know if I can do anything for you."

Keith finally noticed the two who had saved him. It was a middle-aged couple, likely in their forties, who had saved him. They looked unremarkable but happy at the same time.

"Nah, there is no need for you to repay us or anything. We helped you out because we wanted to, not to make you owe us or anything."

"Though, if you do want to repay us, I will not say no to some money-"

The husband closed his wife's mouth before she could say more. The wife appeared to be offended but it was a fake expression on her face. These two were a harmonious couple who loved each other.

Looking at them warmed Keith's heart.

"I understand. I have a lot of money so please accept some of it from me. You did likely save my life after all."

Keith did not have many memories of his parents but he did know they were not happy with each other. That was why he liked to see people be happy with their choices in life.

"No, there is no need-"

"Well, since you offered to give us money, I better not refuse you. I don't want to break such a cutie's heart after all."

Keith laughed at the female's attempt to dodge her husband and take Keith's money. He was happy to see these people and soon, it was time for the dungeon raid to begin.

pαndα`noνɐ1--сoМ Keith got up to leave but the other two got up as well with him.

The elder woman looked at Keith's silent stunned face and gave a small laugh at his expression.

"Yeah, we are coming to this raid as well. Why? Did it surprise you to see such an old couple participate in this raid as well? But you better not underestimate us because we are very powerful."

The woman made a slashing motion with her knife, showing her incredible combat skills.

It looked a little clumsy to Keith's eyes but who was he to know how one's combat skills worked or how they did not work?

He just knew that these people were his benefactors and he needed to protect them. So, he decided to take his protection ring out and hand it over to the elder male.

"Here, keep this for the duration of the raid and nothing shall happen to you. Be sure to stay together and I wish you the best of luck. And remember, it is a loan, not a gift.

The couple took his ring with a hesitant expression but Keith made sure to stress that he would be getting this ring back.

But honestly, it was not like Keith had handed this ring over without a plan. He no longer needed the ring for overworld since his earring could create a strong shield that did not need a precise measurement of mana.

He was sure he would survive a 'basic' dungeon on his own.

"Ah lad, I don't know how to thank you for such a precious lend. I will make sure nothing happens to it for as long as I have this in my possession. And may we both overcome this obstacle and go back home."

The elder man prayed and Keith prayed with him. They did not know each other's name or identity, but they had formed such a precious connection with each other. Keith was happy to have someone like this in his life.

"Hey, if you are done here then let's head out now. We will be late for the dungeon opening if we stay here any longer."

The older woman reminded Keith and he led the way toward the dungeon opening.

As expected, Katy was at the center of the party and she was also the leader. There were about 20 people in the circle, most of them rookies who were going to have their first raid.

"Alright, now that everyone is here, allow me to introduce myself and our plan for this fight."

Katy's loud voice caused everyone to pay attention to her. And Keith had to admit that she was a good leader who could command the masses easily.

He also paid attention to his role and was not surprised to see that it was of an attacker.
