Just think about it: he has a powerful Noble Phantasm, great strength, is handsome, is the son of the Sun God, has a relatively gentle personality, and besides a small issue of being a human lie detector, which is hard to say whether it's an advantage or not, the most important thing is that he is incomparably obedient. The type that if you point east, he will absolutely not go west. He will even do his best to ensure your safety.
If you don't summon such a Heroic Spirit as your Servant, who else would you want to summon?
Don't tell me Gilgamesh is very strong. Yes, Gilgamesh is very strong, but besides the young Kid Gil... whether it's the tyrant Gilgamesh or the Wise King Gilgamesh, are you sure that these two will listen to your command, and not that you will be the one kneeling on the ground listening to their command?
In any case, after hearing Amakusa Shirou's words, this son of the Sun God nodded directly. There was no need to ask for any reason. As long as it was beneficial to his own summoner, then he would do it. That was all.
At the same time, Amakusa Shirou looked at Aslan. "Lord Aslan, would you like to go and see?"
Aslan was stunned for a moment, and at the same time, raised an eyebrow. He had not expected Amakusa Shirou to trust him so much, to let him go with Karna to intercept, or even directly take out, Saintess Jeanne. Was he not worried that he, as a Son of God, would side with Jeanne, who was a Saintess?
If Amakusa Shirou changed his "salvation of all humanity" to the wish he had spoken of, the "sublimation of the souls of the good after death," then it should not constitute the premise of the world's destruction. Strictly speaking, Jeanne and Amakusa Shirou were not so clearly opposed. The main reason was probably that in order to realize his own wish, Amakusa Shirou was worried that Jeanne would have an influence on him.
"Amakusa... before I answer your question, I must ask you again. Is your wish still to achieve the salvation of all humanity?"
Amakusa was also stunned for a moment. Aslan's question... to be precise, a long time ago, after Aslan had expressed his own confusion about his "salvation of all humanity," Amakusa, who had finally calmed down and begun to think about his ideal, couldn't help but feel a bit of agreement with the doubts and thoughts that Aslan had raised. But it was precisely because of this that to have him give up an idea he had insisted on for so long was indeed a difficult choice. What's more, the love in his heart did indeed include those who had made mistakes. Therefore, he could not agree with what Aslan had said, the salvation of only those who were perfectly good.
That pair of deep golden eyes reflected Aslan's back. "The perfectly good, I will save. Those who have erred, I will also save. I will give them another chance, a chance to admit their mistakes. If they still will not awaken, then let their souls fall into hell to accept punishment... The me of now, what I probably want to do is to clarify the legend of 'reincarnation' in this era!"
Hearing the words of the young priest before him, Aslan had not expected that a single question from him would actually make this priest change his so-called "salvation of all humanity" to a "new era of reincarnation." Was his eloquence really that good?
No... to be precise, is Amakusa so good at changing his own ideas?
Seeing the confused look in Aslan's eyes, a slight smile appeared on Amakusa's face. This smile even had a small component of a successful prank. Then, this young priest reined in the smile on his face, his expression becoming serious. "Since I know that the salvation of all humanity could very well lead to this world not changing at all after its sublimation, and could even destroy the existing world... under such circumstances, how could I not change my mind?"
Amakusa clenched the cross hanging around his neck. No matter what, he would not betray his own faith, nor would he forget his original intention of wanting to save the people of the world. "When the ending could possibly go against my original intention, I will naturally not gamble on that possibility of success. In your eyes, Lord Aslan, am I just such a person who acts willfully without listening to others?"
Aslan was constantly shouting in his heart. If it weren't for the fact that in his impression, the young priest before him often caused trouble, he wouldn't have been worried to this extent. No matter what, he didn't want to stand on the side of the villain. No matter what, he was also a good person. If his words could change the future where this world might be destroyed, then that would be for the best.
He smoothed over the roaring in his heart. After all, although he knew that the priest before him was extremely fond of causing trouble, the one before him was just a wisp of a split spirit of his main body. He naturally didn't know more about the world's situation. What's more, in FGO, compared to causing trouble, this young priest, in that world, was more of a kindergarten principal... Mr. Christmas Mask... So why on earth would a certain scumbag musician lend you his mask!
Aslan looked at Amakusa Shirou before him and added in a calm tone, "Swear it in the name of the Lord?"
Amakusa Shirou nodded, his finger tapping his own cross. "I swear it in the name of the Lord!"
Upon hearing these words, Aslan's constantly tense nerves were completely relaxed. Since that was the case, he would go and see what Jeanne's side was thinking.
Aslan stood up straight, then patted the non-existent dust from his body. He then took out a motorcycle full of a futuristic sci-fi style from his own spatial box. Magical energy swept over his body, and the casual clothes he was wearing instantly turned into a biker suit, and at the same time, a pair of goggles appeared. As for a helmet, that was not important for Aslan. How could a heavy fall cause a fracture in his half-dragon's head? Compared to worrying about his head, one should worry more about how big a crater would be left on the ground after he fell, and how much money and energy would be needed to repair it.
Shakespeare, standing at the side, upon seeing this series of actions by Aslan, couldn't help but spread his own arms and begin to marvel at Aslan's integration into this era. If it weren't for the fact that his own experience and understanding of this era were too little, perhaps the Shakespeare of this moment would be enthusiastically trying to write a modern sci-fi story.
Amakusa gave the two of them Jeanne's current location. The Little Sun turned into spirit form and disappeared from his spot. Aslan, on the other hand, did not intend to wake up Melusine, who had already entered a state of rest. After all, this was just the opening battle. He also had to keep some trump cards for the end.
As magical energy was injected into the futuristic-feeling motorcycle, Aslan's figure instantly disappeared from the church.
