Zelretch looked at her. "Arc, what's happening and why is there a boy glowing and convulsing on the floor?"

Arcueid looked at him. "What happened was..." as she explained everything.

Satsuki grasped his hands. "Can you do anything to help him, plz?"

Zelretch nodded. "Ok, follow me," as his sword glowed like a rainbow. He slashed, and a portal opened as he went in.

The girl grabbed Shirou and followed in as they saw they were now in a laboratory of some kind.

Zelretch then took out a small box, placed it on the floor, and it enlarged into a trunk. "Put him in here," he said as he opened it.

The girls did as Zelretch closed the trunk's top.

Satsuki looked at the trunk. "So, what is this?"

Zelretch smiled. "A special box made with the help of a True Magic. It traps anyone inside it in a parallel pocket dimension frozen in a moment of time—perfect stasis."

Arcueid nodded. "But we can't let him stay in there forever."

Zelretch nodded. "I know, but we have to until we find a solution."

Satsuki looked at him. "What do we do now then?"

Zelretch hummed. "You stay here. I will go fetch someone who can help him."

They nodded.

Zelretch then went to the Observatory as he looked through the Multiverse and found what he was looking for. He opened a portal and went in.

A while later, Arcueid looked as she saw Zelretch come along with a woman beside him.

Arcueid blinked. "Grandpa, who is she?"

Zelretch smiled. "Meet the Unknown Magician of the Third Magic, whose name she has forbidden me from speaking."

The Third Magician looked around. "So, who am I to help with vampirization?"

Zelretch smiled. "He is in the trunk. Guys, bring him out," he instructed as Zelretch then took out the new Class Cards he had made after studying the effects Class Cards had on Miyuverse's Shirou. He took help from the true masters of Spiritual Evocation Magecraft, Alchemy, Body Modification via Magecraft, Beast Magecraft, and Magicians who could use the First, Third, and Fifth Magic to make the effects more interesting.

Satsuki and Arcueid took out the convulsing Shirou and placed him on the floor.

Zelretch placed a card on Shirou, one containing the copied soul and power of Shirou from another world who did not have a Reality Marble but was instead given cursed demi-servant flesh before being saved by Kiritsugu using Avalon. In this world, Kiritsugu trained Shirou as the next Magus Killer to make him save Illyasviel. He also had the Origins, Elements, and Sorcery Traits of Curse, Flesh, and Fire. This Shirou had also been trained by various teachers Kiritsugu hired, and after Kiritsugu's death, Shirou was trained as a martial artist and assassin by the YOMI Organization. This Shirou was also an expert in Fire, Curse, Familiar Making, Bounded Field, and Healing Magecraft. He had also mastered the complete Time Alter spell. After Yomi was destroyed, Shirou fought in the Fifth Holy Grail War, joined the Burial Agency for protection, and later became a Counter Guardian after asking Alaya for power to defeat the Wave of Dead Apostles.

Zelretch smiled. "Install," he said, watching as Shirou gained red armor similar to Archer's.

He then pulled out the next card containing the copied soul of Artoria Pendragon and placed it on Shirou's chest. "Install," he said as Shirou gained a set of silver and blue armor.

Zelretch continued, installing the Berserker Arcueid card, the Lancer/Caster Scathach card, the Ruler/Saber Ibuki-Douji card, the Caster/Berserker Sumire card, the Berserker/Caster Altrouge card, the Assassin Kiritsugu EMIYA card, the Saber Card [Shiki Ryougi, and finally the Saber/Caster Shirou card—True Magician with the First Magic who also does not have a Reality Marble.

The Third Magician looked at him. "Really?"

Zelretch nodded. "Yep. Get to work. I also have these," he said, pulling out two vials.

Satsuki looked at him. "What are those?"

Zelretch smiled. "In my left hand is a vial with a potion made by Noritaka Emiya that turns someone into a complete Dead Apostle by skipping all the steps. This one is a complete version, unlike the incomplete version in this world. In my right hand is 'Ideal Replica,' another drug to turn someone into a Dead Apostle by skipping all the stages. This is a unique variant," he explained, loading the two potions into an injection syringe gun and injecting them into Shirou.

"GAHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!" Shirou screamed as his body thrashed and convulsed, his muscles tearing themselves apart.

The Third Magician used her magic to locate the different energies fighting and transforming Shirou's soul. She began weaving them together, altering the curses and changes embedding themselves in his soul. Unable to stop the processes, she instead focused on modifying them, intending to turn the boy into a unique kind of vampire. She carefully wove the changes brought by the energies together as seamlessly as possible, fusing various parts of the copied souls into Shirou and permanently melding them into his soul to help him adapt. She ensured his personality remained mostly intact, though the transformation inevitably altered both his soul and body. As the process neared completion, the changes became more apparent.

Zelretch whispered, "Awaken his new origins as well during the vampirization process, please."

The Third Magician gave him an annoyed look but complied, awakening his origins. Shirou then glowed blue as his soul and body began to transform from the inside out due to the awakening of his origins. These changes merged with the energies, further altering his body in tandem with the vampirization and Class Card transformations. The Third Magician carefully intertwined and combined the processes, struggling to maintain stability while ensuring that neither his personality was altered too much nor his life endangered. She reinforced and strengthened his soul as much as possible without allowing him to transcend entirely, indirectly fortifying his body in the process. His flesh and soul then sublimated to a higher plane of existence, though it stopped short of turning him into a higher lifeform—one of the intended outcomes of her magic.

A while later, the Third Magician looked as the process was complete. She stood up. "It's done."

Satsuki looked and noted the changes in the boy. His hair was now pure snow white, his skin tanned, and his body had grown a bit more muscular as well.

Zelretch smiled. "Ok, the process is done," he said as he tapped Shirou's chest. "Uninstall." Just then, the card appeared and broke into particles. "Huh, seems they are destroyed. Oh well. Anyway, Arcueid, have fun explaining this to your world." Zelretch raised his sword and opened a portal, grabbing the Third Magician and stepping in.

Satsuki blinked. "What happened?"

Arcueid groaned. "Damn it, that was a different Gramps."

The door opened as Zelretch walked in. "What's going on and why are you here?"

Arcueid sighed. "Your other self helped and pranked us at the same time."

Zelretch nodded. "So, mind explaining?"

Satsuki nodded. "It all started when..."

Soon the story ended. Zelretch nodded. "I see," as he went to the boy and opened his eyes, seeing they were still golden. He checked his body and blinked to find physical magic circuits and a pair of weird Mystic Eyes. Zelretch hummed as he realized some Shirou Emiya variants had managed to accidentally replicate the Lusendra Family Magecraft of turning their bodies into magic circuits, but never to this extent. From what he could grasp, 7,000 nerves, 2,000 capillary vessels, and 8,000 muscle fibers were all turned into good-quality magic circuits that felt very odd.

Arcueid looked at him. "Is he ok?"

Zelretch nodded. "He is, and he is a Dead Apostle, though his body is weird."

Satsuki blinked. "What did your other self do?"

Zelretch shrugged. "I'd have to run a few tests first," as he took out his sword and started using diagnostic spells.

A while later, Zelretch finished his spell. "Well, it seems all the chaos caused his origin to awaken. It's why his body changed so much, plus it altered both types of his magic circuits permanently."

Satsuki blinked. "Origin?"

Zelretch nodded. "It's basically your instinct. It's the starting point and driving force that defines one's existence and directs one's actions throughout life. Generally, it can either be expressed heavily or it can be subtle. But if a person becomes awakened to their origin, it becomes nearly impossible to stray from their origin."

Arcueid nodded. "What's his Origin then?"

Zelretch hummed as he took a ball of Quicksilver and used his spell to control it, forming a magic circle. He placed Shirou on it and started his ritual. Soon, he got the result and changed the magic circle to perform another ritual to find Shirou's Elemental Affinity and then his Sorcery Traits. Once he was done, he stepped back.

Arcueid hummed as she saw Zelretch finish. "So, what is it?"

Zelretch Sighed. "It, seems he has the Origin's of Weapons, Creation, Sword and Nothingness, with Elemental Affinity of Weapons, Sword, Nothingness, Fire, and Flesh, The Sorcery Trait's of Wisdom of 「 」, Sword, Supreme Healing, Barrier, Absolute Defense, Reinforcement, Alteration, Change, Vessel of Spirits, Invocation of Spirit, Assimilative-Adaptation, Heat, Entropy, Curse, Flesh, Temporal Operation, Dominating Ruler, Progression, Draconic Sovereign's Power Burst, Realization of Imagination, Sanctification, Almighty Runes, Flow, Binding-Contracts, Connecting to 「 」, and Materialization of Impossible."

A While later, Shirou's eyes fluttered open as he looked around. The world felt sharper; hidden details in the darkness, once invisible, were now as clear as day. Atremendous power coursed through him.

Satsuki looked at him. "Hey, are you okay?"

Shirou nodded. "Yes, thank you. Did you save me?"

Satsuki nodded. "It's complicated, but essentially, yes."
