"So, you're saying that you, like Tia, came here from another place, then married Tia's mom and even had Tia. Then, for reasons we don't know, you changed your name to Guy Tia, is that right?" Lancelot summed it up.
"Bingo! You got it!" Dad's lips curled up in a smile.
"Dad, were you... always like this?" Tia suddenly asked.
"The original me?" Dad was taken aback for a moment, then smiled. After that... Dad began to change his appearance.
When Dad finished changing, Tia was so shocked that she didn't know what to say.
The Dad standing before her was clearly a grown-up Emiya Shirou.
Dad was also an Emiya Shirou who came from somewhere else, or rather, Dad really was an Emiya Shirou who came from somewhere else?
But in the next instant, Dad's outfit suddenly changed, turning into... Senji Muramasa's outfit.
Tia was stunned again.
What's going on?
"Tia, do you think I became Emiya Shirou and then had you through your mom?" Dad asked with a mysterious smile.
"Isn't that what happened?" Tia asked back.
"Of course not! I directly became Senji Muramasa!" Dad's statement shocked Tia again. "Remember the Sixth Lostbelt? Remember how Senji Muramasa left in the Sixth Lostbelt?"
Tia nodded.
"At the moment Senji Muramasa disappeared, at the moment he was about to return to the Throne of Heroes, I traveled through time and took over his Servant body," Dad said.
You can travel like that?!
Lancelot was also stunned.
"There's one thing I still want to ask. That god-eating Senji Muramasa..." Lancelot asked.
"Of course, that was me!" Dad said as a matter of course.
"No wonder..." Lancelot nodded. "By the way, where is this place?"
"It's the Servant Hall!" Dad said even more naturally.
Tia was stunned again.
"I... am I really a Servant? That evil god Angra Mainyu?" Tia suddenly remembered the good god Ahura Mazda's words.
"That's one of the many identities I arranged for you, to make it easier for you to experience reincarnation over and over again."
"Reincarnation?" Tia thought for a moment and understood. After all, Tia had learned about the previous reincarnations from various sources. "But why did you want me to go through reincarnation?"
"Because Dad wants to turn this Lostbelt into a real parallel world that can continue to exist. Only then can our family live together," Dad sighed.
"Tia, Dad broke a part of this world's normal operation to marry me, which caused this world to become a Lostbelt that is destined to disappear," Mom said.
"Yeah," Dad nodded. "Back then, in the Seventh Singularity, I followed Gudako as Senji Muramasa and defeated your mom, and then married her. But this action led to the collapse of the entire Babylonian mythology. Sigh..."
"You're still sighing? You beat up all the Babylonian gods back then," Mom said, looking at Dad with a smile.
"If I didn't beat them into submission, how could they let me marry you?" Dad said matter-of-factly.
Tia and Lancelot were stunned again, listening to Mom and Dad's back-and-forth conversation.
"The Babylonian mythology system... collapsed?" Tia asked.
"Yeah, we're now in the world after the collapse. Because your mom is Tiamat, the creator goddess in the mythology system, and I... I directly broke into the Imaginary Number Space and forcibly brought your mom's main body out, and forcibly took her away from Babylon and left the Sixth Singularity," Dad said. "After that, the entire Babylon began to collapse. When I returned to Chaldea, the Babylonian mythology system had completely disappeared. Of course, the gods themselves wouldn't die easily, and the Babylonian region was still alive and well. The world would still operate normally, but the mythology system is part of the foundation that makes up this world, especially the creator goddess in a mythology system like your mom, who is also the Second Beast. Therefore, the entire world began to be recognized as a Lostbelt at that time."
"For some reason, a new Second Beast has never been chosen, and I... am just your mom now, unless I give up all this and return," Mom said. "But I don't want to return. I just want the present. So Dad decided to let you inherit my position for my sake. But your identity is naturally unsuitable. To make you successfully inherit my position, Dad designed the world as it is now, allowing you to successfully achieve reincarnation through Spiritron Dives. Every time you reincarnate, you become stronger each time, until now, you have successfully achieved the goal we wanted to achieve."
Dad also nodded: "According to usual reincarnation, after you return to the Servant Hall as Angra Mainyu, you will be summoned as Angra Mainyu in the Third Holy Grail War. However, due to your current special nature, you and Lancelot are completely integrated into one person in the Servant Hall, and a new personality has been created to replace you and Lancelot, becoming the Ruler class Angra Mainyu. As for the original you and Lancelot, we have naturally preserved you, waiting for your rebirth. As for the setting that the world was on the verge of destruction when you were born 17 years ago, that was a setting to make you stronger over and over again. I was imitating what Homura Akemi did to Madoka Kaname to train you."
"Alright, go now, Tia. The current you is Emiya Shirou, also Angra Mainyu, the creator goddess of Babylonian mythology, the new Second Beast, and Gudako's dad. You can do whatever you want," Dad said finally, waving his hand.
"Go, Mom and Dad's mission is complete. Mom and Dad are going to play in other worlds," Mom said finally, then waved her hand.
"Huh? Wait! What about me after you leave? Didn't you say you just wanted a peaceful life now?" Tia immediately panicked when she heard this.
"A peaceful life of travel!? Dad always tells me about other strange worlds, and Mom has wanted to go for a long time," Mom said with some longing.
"Don't worry, Mom and Dad's spirit cores are in Chaldea. You can summon us anytime you miss us," Dad smiled slightly.
"But according to the current storyline time, Chaldea summoned Mom, but didn't summon Dad," Mom covered her mouth and chuckled.
Dad shrugged: "There's no way. Chaldea has to fight for another 10 years."
At this time, Tia suddenly heard someone talking in the Servant Hall. Listening carefully, wasn't it Ahad's voice?
"Alright, you should go now. This time, you have to act as an Avenger in the normal timeline, so that the world can return to normal operation," Dad urged finally.
Tia pouted, then watched Dad and Mom disappear.
At this time, Tia and Lancelot looked at each other.
"Let's go, Master, uh~ no, Tia, let's act as Angra Mainyu for a while," Lancelot said with some helplessness, but also found it very interesting.
