A self-taught Magus and an avid fantasy reader ends up inside the Tower of God with Mordred's power and with Mordred's soul inside his Ignition Weapon as a result of his wish to the Holy Grail. ... Summary: The Main Character participated in a Holy Grail War and ended up being the final winner thanks to wit and luck, but at the cost of his Servant Mordred. As a result of his subconscious wish to the Holy Grail (it seems), he gained various powers similar to those of his Servant, his dead Servant Mordred was restored and took refuge inside his sword, and the two ended up inside the world of the Tower of God. Over time, he discovers that the Tower is exactly a place where he can fulfill his various desires and wishes as promised, growing more powerful and achieving more than just a single wish could grant him. ... It is mainly a Tower of God story. The only aspect from Fate verse is the MC and his powers. The goal for the Main Character is to grow his powers and live an interesting life in the new world. PS: Mordred is not a romantic interest. This is not her character. She is MC's platonic female friend and partner/Ignition Weapon for the majority of the story, since the base of her character design is a child seeking attention. The other girls from TOG are the heroines, and mainly Endorsi. I wonder what the response and popularity would be like. I also like the fact that the MC's powers here are quite straightforward, and it makes things easy to write.
"Woah, you were amazing, Sir Isaac! I didn't notice that hint about the real doors at all," Bam said while innocently smiling at Isaac.
"I just got lucky." Isaac faintly smiled.
As the three left the testing room, Bam looked relieved and happy while Isaac was relieved and satisfied.
Only Khun's expression was dark as he walked in the back.
'Don't try to always solve everything by yourself.'
'Don't forget to rely on your teammates. Don't overthink things.'
Han Sung's words reverberated in Khun's ears. And it felt as if it was a jab aimed straight at his incompetence.
'Damn it! Why didn't I see the clues?' Khun cursed at himself inwardly.
He was supposed to be the brains of the team. He was supposed to be the smartest.
In other words, not noticing the clues that Isaac noticed was his failure.
'I was so useless…'
He also didn't quite like this test, but the truth remained that he was simply useless.
The hint outside in regard to the differences between the timing of when the various teams finished, and the subtle world play in the Test Administrator's words… They were both very simple, but he failed to notice both.
If not for Isaac, who noticed them at a glance, he might have even missed them!
His intelligence, which he was an asset that he was always the most proud of, turned out to be useless here.
At this rate, did Isaac even need him?
Thinking this at the back of his mind, Khun slowly turned to expressionlessly look at Isaac who followed a guide robot to lead them to the gathering room.
"What's up?" Isaac asked with a light smile as he noticed Khun's strange gaze.
Khun shook his head and formed a small smile. "Nothing. I only thought that I was quite useless during this test. You basically solved it yourself."
Bam smiled a little, as if tacitly agreeing because he also felt quite useless.
[Yeah, you did great, Master! I guess that's why you're the Master.]
"Well, I got lucky…" Isaac shrugged.
In truth, he was a little happy that he noticed the hint in Yu Han Sung's words about 'real doors' because it was something that he had come up completely on his own; he didn't rely on his manhwa knowledge for this.
However, he still felt that it was a lucky find - because he already had a strong clue that they could open any door, he had the leisure to think about things like that.
But he still felt that he certainly needed people like Khun.
Isaac placed a hand on Khun's shoulder and told him with a small smile, "I got lucky this time, but I'll need you in the future. We're a team."
"Hm?... Sure! I'll show you guys just what I can do!" Khun smirked.
However, it was clear to him that Isaac was only polite.
'I'll have to do better on the next test.' Khun secretly squeezed his fists.
…
Inside the gathering room, Isaac's team picked a random bench and sat down together.
Soon after, Isaac noticed Shibisu walking toward them.
After approaching the group, Shibisu raised his hand at Isaac with a friendly smile. "Hey, Isaac! I knew that you would all pass! Haha."
"And you passed as well." Isaac smiled. Both his hands held precious weapons, so he simply smiled in a greeting.
Shibisu placed his hands at his hips and said, "Yeah, that test wasn't too hard. And after I noticed you watch how long the other teams took to finish their tests, it made things even easier, haha!"
"Haha, I had a feeling that you're a sharp guy," Isaac casually replied.
And Shibisu touched the back of his head in embarrassment, saying, "Haha, I'm a pretty normal guy…"
Isaac slightly smiled. Strength wise, Shibisu indeed was not exceptional at all; he was even weak. Even so, he seemed to be an important character in the story and had a good head on his shoulders.
Shibisu turned toward the other two sitting next to Isaac and said, "By the way, my name is Shibisu. I already know Isaac, but I'm not too familiar with you two."
"My name is Khun Aguero Agnes, I'm from the Khun family." Khun smiled courtly as he stood up and extended his hand to Shibisu, staring at him with a look of superiority.
With a somewhat nervous smile, Shibisu shook Khun's hand. "Haha, nice to meet you…"
After that, Bam also meekly extended his own hand. "I'm Bam, the Twenty-Fifth Bam. Nice to meet you."
"Yeah, I remember you, lucky guy." Shibisu chuckled as he shook Bam's hand. "It's amazing for someone who looks so ordinary to make it up here. It seems you're quite special."
Bam smiled sheepishly. "No… not really. It's all thanks to my teammates."
"The humblest ones turn out to be the scariest, haha."
After some more small talk, Shibisu returned to his own team.
When this happened, Isaac focused on the Clarent in his right hand, with Mordred's spirit inside.
Isaac thought of something and asked, 'Saber, how much energy did it cost you to ignite on the first floor?'
[Ah, about that. I used very little energy that one time. It isn't worth mentioning.]
'Hm? Very little?'
[Yeah… I probably used up about 10% of my strength.]
"What?!"
What? Only five percent?!
As Issac suddenly spoke up, Khun and Bam looked at him in surprise.
Isaac shook his head. "Nevermind, it's nothing."
"Oh, okay," said Khun, slightly frowning. What was that outburst?
Isaac ignored him. After regaining his focus, he asked Mordred again, 'What do you mean you used 10% of your strength?'
[Hehe, well, I guess I should make it clear. I used around 10% of my total energy. As for the attack against the Ball, it was around half of my strength. I felt that going all out would be overkill. By the way, Clarent Blood Arthur became much stronger.]
'Ah, I see…'
It was more reasonable, but still surprising.
It seemed that Clarent had some amazing energy reserves!
At the same level as before, which had easily cracked the Ball that even his strongest sword strike couldn't, he could ignite Clarent for about 10 times in a row.
Not only this, but [Clarent Blood Arthur] was also strengthened considerably inside the Tower.
In truth, there also seemed to be more than one way to activate [Clarent Blood Arthur], so Isaac hoped to experiment with it in the future.
As time passed, eventually all teams finished participating in the test and assistant Yellowy announced a 30-minute break.
The break time was rather uneventful. The three in Isaac's team didn't talk much, but as they all silently sat together, Isaac could still see that the atmosphere was rather comfortable.
During the break, Isaac tried to explore some more mysteries of his powers inside the Tower and also secretly chatted with Mordred.
At one point, Mordred said, [Hey, Master… So we didn't have a good chance to talk about it before, but what was it that really happened after the final fight? You… used a wish to bring me back, did you?]
Before this, when they appeared inside a weird underground space still before being summoned to the First Floor, Isaac only had a chance to say that their situation should be because of the wish he made, but that's all he told her.
'... Yes, it seemed to be a part of my wish. I feel that… I wanted to bring you back,' Isaac said honestly with a small smile.
[Master…] Mordred said in emotion.
Isaac faintly smiled. He felt it was the truth.
Mordred, although quite childish, reckless and sometimes stupid, had taught him to be more honest with himself and was his first and only friend.
Concentrating on his connection to Mordred, Isaac continued, 'Well, I don't know if it's what you wanted. All of this happened very suddenly. Even I was surprised that this is what happened.'
[No, Master, it's okay. I already figured things out during the war, so I didn't care about the wish anymore… So, thank you. Thank you for wishing to have me around.]
As Mordred said the last words with a sniff as if she was about to cry, it caused Isaac's eyes to slightly glaze over.
He knew that Mordred had traumas related to her 'father' whom she admired not having any expectations of her; he happened to see it in his dreams. As such, she should have been happy that someone wanted her around and wanted to rely on her.
[Hey, Master. This Tower seems like an interesting place. Since we're already here, let's crush those tests!]
'... Yeah.'
During the break continued, Isaac took this chance to observe some of the Regulars in the room using his Instinct skill.
[Instinct A] didn't give him precise data like some kind of game system, but he could still use it to roughly feel out the threat level and the physical ability of the Regulars around him.
Firstly, he already saw Khun as someone who was not a threat at all - he was far stronger than Bam, who appeared as an ordinary person, but was not a threat..
For Hatsu and Rak, they were similar to Khun; for Rak, he was probably slightly less weaker.
The only person here that made Isaac feel like a threat was Anak. She still seemed significantly weaker than him, but she couldn't be ignored.
She already gave him the feeling of a weak-ranked Servant like the Assassin he saw during the war.
The other Regulars seemed only slightly superhuman, but Anak was on another level, and this didn't even include the strength of her weapon.
'It's the effect of the Blood of Jahad and her physique, huh?'
Thinking this, Isaac then asked Mordred, 'Saber, how do you think we would fair against a Ranker?'
[A Ranker? Like that Pikachu or crossdresser guy?]
'Yeah.'
Mordred spoke in a complicated tone: [You know, Master, it's hard to say. People here don't have any Magical Energy, so it's difficult to judge their level. What my gut tells me is that that guy is physically strong, I can say that... But if it was just that, we might be able to beat him at full strength. But he still gives me a bad feeling. It's better not to try it.]
'Well, okay.' Isaac couldn't imagine a Ranker not using Shinsoo to fight.
[And with that Yuri girl, there is no chance at all. Seriously, Master, just that woman's body seems like it's a Noble Phantasm.]
…
As the break was slowly reaching the end, Khun stood up and excused himself to visit the bathroom.
Isaac noted how Khun's bag seemed much lighter in his hand afterwards, but he kept it to himself.
At one point, the electric door slid open as Lero Ro entered the room with the assistant Yellowy at the side.
"Did you have enough rest, Regulars? I'm so happy to see you again!" Lero Ro spoke up with an excited expression.
"Oh! Mr. Lero Ro!" Bam smiled when he saw the Ranker he had a good impression of.
Lero Ro smiled as he raised his finger. "I came here… with very good news."
"Good news?" one of the Regulars asked.
"Yeah! I talked with the Test Director before I came here and he told us to give you a bonus game!"
At that, Shibisu raised his hand as he politely said, "I'm sorry, but I don't think it's in our best interest to take more tests than necessary."
"I'm sorry to hear that, but the bonus game has nothing to do with the tests. It is up to each team to choose whether to play the bonus game or not. There is no penalty if you decide not to."
As Lero Ro clarified, he managed to calm down some of the more cautious teams.
Lero Ro then continued, "But the winner of the bonus game gets to pass the final test of this floor. They get the right to go straight to the next floor."
Hearing those words, the Regulars looked at Lero Ro with interest.
Among them, only Isaac remained indifferent.
"Gets to pass to the next floor? Then what about the remaining tests?" Khun asked, appearing moved.
"They don't have to take them," Lero Ro replied.
And the crowd of Regulars seemed to be very intrigued as they began reacting.
"Wow... that's a huge advantage!"
"It is a big chance…"
"But that luck to move on to the next floor goes to only one team…"
'Is skipping a free month of training under Rankers really an advantage for those who would pass anyway?' Isaac thought inwardly.
"So, what is the bonus game?" someone asked.
At the last comment, Lero Ro spoke up, "This game is called the 'Crown Game'. I will explain the details to you when we get to the game spot."
