Amakusa Shirou Tokisada. In Japan, he was a devout Christian believer endlessly close to a saint, also known as the miracle boy.
Summoned as a Ruler in the Third Holy Grail War, he lost his contractor right before his eyes. It was just like during the Shimabara Rebellion suppressed by the government, losing someone who shared his cause.
He does not seek revenge. He holds no grudge. However, he does have a slight selfish desire.
He is not strictly a saint. Though endlessly close to a saint, he is insufficient to be called a true saint. In some parallel worlds, he even becomes a fallen avenger, and he himself believes he is lacking to be a saint.
Yet, he had dreamed of something since his lifetime.
Human salvation.
To save all humanity, he intends to use the Third Magic of the Greater Grail to materialize the souls of all humans worldwide, on Earth, and create a world of peace.
It's a noble goal, but with just the Third Magic, it's an impossible task.
Especially since the Servant Universe, where all humanity are Servants like the Third Magic, has proven it. In the universe where X and X Alter live, even if they die and revive later, there are still wars, evil organizations, criminals, etc. It's a chaotic world with many bounty hunters and guilds of planetary-scale bounty hunters.
With just the Third Magic, it's impossible. Unless it's the Sixth Magic of salvation, whose true nature is unknown, the mere Third Magic of immortality is insufficient. Even in the Third Magic, death exists, so it's not perfect.
Tap... tap...
"Assassin. The Hanging Gardens is fully completed, I see?"
Of course, he hasn't experienced such a world, so he doesn't know. Yet, he moves with the belief that this is not wrong. For decades, he lived in the present world, amassing wealth, and with that wealth, he tirelessly worked for decades to procure numerous materials from Semiramis's homeland to build the Hanging Gardens.
He admires the completed magnificent Hanging Gardens when...
Snap!
"... My, Command Spell...?"
And his Command Spell disappears just like that. The contract with his Servant is severed. He panics. This place is known only to him and Semiramis. Who could have handled Semiramis, a mythical magus, without him knowing...
"Who on earth..."
"It's me, you bastard."
"!?"
And behind him, Dumpty appears out of nowhere. He smiles and looks at him.
"Materializing, no, incompletely materializing and living for decades. And a Servant becoming a Master. Interesting, isn't it?"
"... You're not the Black Master, but the mysterious Master Archer mentioned."
"Correct~ But I won't give you a gold star? Anyway, you prepared something grand, huh? Amakusa."
"You know my name. What is your identity? In my preliminary research, there was no such person. Not from the Church, not from the Mage's Association. Definitely not the Burial Agency, are you from Atlas? They might be interested in the Greater Grail."
"Nope? How could that be? I'm not interested in that."
"Then what is your identity? I heard you command multiple Servants..."
Amakusa carefully activates his magic circuits, pulls out a black gun, and throws it at him.
Smash!
And the black gun he threw quickly turns to dust. The talismans floating around Dumpty emit a brilliant blue light.
"That won't work on me. Your combat ability is at the level of a third-rate Servant, right?"
Indeed, he was more specialized in support than combat. Currently, he hasn't yet stolen Command Spells from other Masters. So, he has no means to summon other enemy Servants. Originally, the Hanging Gardens was a secret trump card, known only to Caster Shakespeare.
"Ah, and that thing is going to disappear?"
Whoooooosh!!!!!!!!!!
As soon as Dumpty speaks, a massive golden light surges up, and the Hanging Gardens shatters into pieces.
"What..."
"Worth unsealing. It's a fortress with top-tier durability, but it can't withstand the power of the holy sword that destroyed Sephirot. I smashed its core, and moreover, with Semiramis herself incapacitated, its durability had to weaken."
"Did you kill Assassin..."
"Kill? Why would I kill such a fine woman?"
"Woman..."
Amakusa frowns at the tone that suggests using her as a plaything. It was a common sight during wars. Men are killed or used as slaves, and women are captured leisurely when the war situation is favorable to be used as labor or playthings.
It was routine even in the Sengoku period. Originally, even without war, being captured and sold to brothels, etc., Japan was a place where such things happened vaguely, so it was a familiar phenomenon to him. Yet, displeased by such things, he frowns and shows his discomfort.
"What have you done to her."
"Wanna know?"
He raises his hand and snaps his fingers with a ~click~ sound, and Ushiwakamaru jumps out from the darkness. She carries a large box and opens it.
"Ah, Assassin...!"
"How disgraceful... To reduce her, a queen, to such a state, you're truly a lowly person. Even though it's a fight for the Holy Grail, to commit such acts... What do you think of Heroic Spirits?"
"Rather, I want to ask them. What do they think of Masters... Now my schedule is packed like a stuffed animal, to the point where I feel deprived of freedom, at this rate, I don't know who's the Servant (subordinate)... No no, I digressed."
Dumpty momentarily reveals his true feelings and complains. Of course, Amakusa doesn't understand at all.
"Well, at least I won't send a promised video, so don't worry. I have a conscience, so I can't do that."
"What is your purpose? You don't kill me immediately... If you even know her True Name, you must know I'm the leader of the enemy faction, right?"
"Ah~ I'm not interested in that. Originally, there's no such thing as you making a wish on the Grail. That's how desire sensors work, you know."
"Huh?"
"Nothing much. Just, I want to crush your dream? A passing Master is a destroyer of worlds. A dream is also a world, so shouldn't it be destroyed? I'm already a demon who has destroyed many worlds. And Amakusa... Your insignificant dream has no meaning."
"Human salvation... is an insignificant dream!?"
"What even a savior couldn't do, you can't accomplish. You fool who couldn't become a saint."
"....."
Dumpty immediately pierces his chest with a sharp argument.
"Conversely, more wars have broken out because of that religion. Sects of religions worshipping the same fundamental god have increased, and harming and destroying others in the name of god has grown more. I'm skeptical of religion. Jesus heaven, non-believers hell~ Cool, right? Now it's the era of coercion? Religion meant to save humans, conversely, causes immense damage. Amakusa, you were like that too, right? In the end, during the Shimabara Rebellion, did the god you believe in save you? Could you save the people?"
"......."
"Give up on such an overreaching dream. I understand wanting to live for ideals, but it's impossible. You have to see reality. You don't know until you try? You're a failure who tried and failed. Your actions were right, but the result was hell. Look now, you pathetic fool who can't even protect one Servant, human salvation? You can't even save one person before you, what dream are you dreaming? Nonsense, if you can't save one person before you... how can that be human salvation? The savior you believe in first saved people before him and gradually gathered believers. Like you in the past. But now, it's different."
Dumpty laughs at Amakusa, and then Jeanne d'Arc walks out from the wreckage of the destroyed Hanging Gardens.
"It's all done."
"I can see that~ Good job. This should be enough. Even if you make contracts with other enemy Servants, without the most important Hanging Gardens, you'll lose to the Black faction. Try doing well once. Save yourself first before saying such things. If you can't see reality, you can't achieve ideals. Ideals alone can't change the world. Some champions of justice have experienced that and despaired. You're just on the same path, so stop."
Offering some advice, Dumpty disappears into the forest with Semiramis.
"... Amakusa Shirou Tokisada. Your dream is mistaken."
Jeanne d'Arc leaves a word and follows Dumpty.
And then, Shakespeare reveals himself.
"Oh my... The despairing face of the saint that the Empress so longed to see? What a pity~ Truly a tragedy!"
"Please be quiet... I haven't given up yet. As long as I'm alive, it's not over... There's still the hypnotic incense Semiramis left. I'll have the Masters transfer their Command Spells."
"I see~! Indeed, I look forward to how you'll overcome this."
Amakusa grits his teeth, clenches his fist tightly, and heads to his base.
For the first time, burning with the emotion of vengeance, his eyes turn red, and he bites his lip hard enough to draw blood.
Meanwhile...
"Really, what's with showing such a figure? I had no intention of showing it to anyone but you..."
"But you cooperated, didn't you~? And among the bunny and maid outfits, you chose that one."
"The bunny has less exposure, doesn't it!?"
"Then will you wear the bunny one?"
"It's all over... I see, you want to see it. Truly, an irredeemable Master. But, since you strengthened my Noble Phantasm, I'll make an exception..."
"You were going to do it anyway, yet you talk so much. Just obediently follow your lord."
"That's also part of her charm, Ushiwaka."
"Really... Master, you have bad taste."
"I won't send a video, but should I take this one and send it?"
"Are you a devil?"
"Says the Jeanne d'Arc who cooperated."
"Guh...!"
"Originally, it's that guy who summoned me wrong. And... at this point, I'm reluctant to have new Servants. Originally, that guy is in a materialized state though."
"Reluctant to have new Servants?"
"I'm a petty bourgeois, you see~ Making new friends is a bit scary? I might accidentally do something wrong and be hated~ If there's no bond, I'm just a background character."
"I really don't understand..."
"That's because you're still a newbie!"
"... Yeah, sure."
Dumpty teases Jeanne d'Arc and hugs Jack. Taking care of Jack, he looks forward to the great war that will happen the next day.
