<Congratulations, you have received "Immortality">
As expected of the main heroine.
Tamazuki sat on the edge of his bed as he looked at the reward given by Irisviel.
Considering Irisviel's position in the story was rather important and was also one of the main heroines, he knew that the reward given by the system would be impressive, and his guess was correct.
Immortality.
The description of this ability was like the name.
This ability gave him an immortality.
Frankly, this ability might be useless, especially when he became immortal after he became the Demon Lord. This should be in everyone's thoughts, but that wasn't the case. It was similar to the "Fire," which he got previously, and this "Immortal" gave him a factor and a talent to develop an ability that was related to immortality.
The common development was regeneration since as long as his regeneration was fast enough, he wouldn't die.
Moreover, it was possible for him to develop abilities that were related to immortality.
Also, the most important thing...
'Ava, is it possible for me to help Shizu?'
'It should be possible, but you need to develop your ability further, Master.'
Tamazuki nodded and felt at ease since developing abilities were simple things for him, especially when he had enhanced learning.
Frankly, if possible, he wanted a power that could share, lend, copy, or give his power since that way, Shizu would be okay.
However, there was no such a convenient thing.
Unless he got his hand on the heroine that had a connection with the type of power he mentioned above, then the chance was low.
Yet, it didn't mean that everything was helpless since, with his power, he could visit various universes. Even if in the one universe, there wasn't anyone with such a power, what about other universes?
Moreover, after his meeting with that "being" in the world of One Punch Man, the development of his ability to travel to another world became stronger. There was no limitation where ten days he stayed in this world meant one day in his original world. Instead, no matter how long he stayed in another world, it wouldn't affect the time in his original world or the other world he had stayed in.
So, as long as he didn't step into the world of Tensura, where Shizu was, he didn't need to worry about the countdown of the limitation of her age.
However, in the worst case, he might let her drink his blood or just take out this "Immortality" ability, then give it to Shizu.
Nevertheless, due to this reward, he was at ease, and everything was quite smooth.
However, he felt conflicted when he thought about the reason why he got this reward.
Or rather, it wasn't hard to tell why he got this ability from Irisviel, but it was also because of this reason; it was quite ironic.
As a homunculus, Irisviel's age was limited.
She was born and set to live and die for the Holy Grail. When the Holy Grail War ended, her meaning disappeared, and she would die.
In other words, she had only two weeks or so of life.
However, before she passed away, her body would be weakened as she slowly died.
So, wasn't it ironic?
He had an immorality, yet Irisivel only had such a short life.
While he was in the middle of a thought, Saber, who was on the bed, didn't sleep like Scheherazade and Irisviel. She lay on the bed with a flushed yet complicated gaze since she didn't expect she would lose her chastity to this man.
Saber was someone who had given her life for her kingdom.
She gave everything to make her kingdom and subjects prosper.
As a matter of feelings? She didn't put that as something important. Even her previous wife, Guinevere, was nothing but a political marriage, and she didn't care much about her, but due to this, she felt sorry since she had wasted Guinevere's life, so even if she knew Guinevere loved her knight, Lancelot, she didn't say anything.
Yet, she didn't expect it was also because of this that her kingdom was almost in ruin, bringing her endless regret and despair.
Fortunately, she was given a chance to fix everything.
However, the Holy Grail was more complicated than she had thought, and there were many powerful foes that she couldn't take on lightly.
Yet, among those foes in this war, the man who had stolen her chastity was the most fearsome.
Even now, her feelings toward him are complicated.
She should hate him, yet at the same time; she also couldn't do that, especially when she thought about the absurdness they had done previously. Her cheeks were tinted with cute blush, and the pleasure still lingered on her body.
Frankly, she should have taken her sword and chopped him several pieces for insolence, but she couldn't do that.
She, who had been strong and the one being depended on, started to rely on someone and even succumbed under him, letting him ravage her body, turning her into something that she didn't want to.
By now, she was afraid.
She was afraid that she might forget her regret, ambition, and wish because of him.
This feeling was dangerous, and she wished to stay away from him, but she knew that she couldn't, especially when she had become her Servant.
Still, when she looked at Scheherazade, she couldn't help but want to applaud this woman since she knew this Servant of his was powerful enough to tame a beast like Tamazuki.
However, her feelings toward him aside, there were many things that she wanted to question him about.
Who was he?
Was he really a Master?
Also, why did he have so much magical energy as if he was a dragon?
Lastly, why was their scent quite similar?
Well, she couldn't say that it was similar, but when her breasts were rubbed by him for the first time, his scent started to change and gave her some similarities, so it was also why when he held her, she was quite at ease somehow.
"........"
She then quickly shook her head since, as a king, how could she fall into such an indulgence?
As a king, she needed to have discipline and not be tempted by the feeling of a woman that made her weak.
Yet, when his eyes stared into her, her heart was beating so fast as if her body was electrocuted. Her body was hot before she looked away from him shyly.
However, Tamazuki, who looked at Saber, was speechless since this woman was a female dragon, especially after she got his energy. Even if she lacked experience and technique, her physical ability was far above Irisviel and Scheherazade.
By now, with his Prana supply, it wouldn't be weird for her to have all A Rank status or even A++ status.
"You are not sleeping?"
Saber didn't really want to answer, but his gentleness made it hard for her to ignore him.
"...no, with your energy supply, it is impossible for me to get tired."
"......."
Tamazuki thought that sometimes it was a disadvantage to have unlimited energy.
"Do you want to talk?"
"........"
Saber fell in silence and glanced at him with difficulty before she nodded hesitantly. "...okay."
