In the world of Type-Moon, start by becoming Morgan's husband!

"But if that's the case—"

"That defeats the purpose of my coming here, doesn't it?"

"If this happens, our meeting will be cursed... I don't want this to happen."

"Besides -"

"I'm sure we'll meet again at some point in the future."

"..."

Black Jeanne was silent for a long time before she spoke as if giving in.

"That's what you said."

"If I don't meet you again in the future...I will curse you forever!"

As if to increase the persuasiveness of her words, Black Joan of Arc shouted at Joan of Arc on the other side.

"Hey! Another 'me', you think so too, right?"

"Nothing." Joan of Arc shook her head.

"I...will never curse my brother."

"Even if he doesn't love me anymore, he must have his reasons."

"So no matter when, I am willing to bless him."

"..."

Black Jeanne fell silent.

She felt a certain gap between herself and Joan of Arc, but didn't know how to make up for it.

The increasingly embarrassed witch could only yell as if she was cheating.

"Forget it, never mind this!"

"Since we are leaving tomorrow——"

Black Jeanne looked up at Ian beside her, her golden eyes revealing an undisguised gluttonous light.

"Is it okay to have fun as long as you want tonight?"

Although she was a saint, Joan of Arc was not unable to understand such straightforward words.

"Are you planning on doing something like that now?!"

"Nonsense!" Black Joan of Arc glared at Joan of Arc.

"This is something we have to do every day. Given the situation today, we can't stop!"

"Eh--!"

Feeling that she had discovered another incredible secret, Joan of Arc quickly asked Ian for confirmation.

"Brother, is this true?"

"...Yeah." Ian did not deny this. "Because looking at her, it feels like I'm with you, so..."

"of course."

The man looked at Black Jeanne on the other side, with a bit more pain and love in his eyes.

“You guys are actually quite different.”

"It's just... this is enough for me to remember the past."

"..."

Hearing this, Jeanne's throat moved slightly.

She grabbed the hem of her brother's clothes.

"Well now... Brother doesn't need to miss me in this way anymore."

"I'm right here, aren't I?"

"Go away!" Black Jeanne shouted, "He is married to me!"

"But he is also my brother!"

Seeing that the two Joans were about to quarrel over this matter, Ian immediately took on the initiative of an older brother.

"Don't quarrel."

The man hugged them tightly, one on each side, and then kissed their foreheads gently.

"Tonight... no one can escape."

A few minutes later, a few more pieces of clothing were found at the head of the bed.

The happy voices of the girls also echoed in the room.

It was a long-awaited complete relaxation, and also a symbol of the melting of all contradictions.

"Sister, it's my turn now!"

"Why are you in such a hurry? Wait a little longer, sister! I've only done it twice!"

"Brother! Look at her!"

"It's okay, Jeanna, come sit on your brother's hand."

“Eh… huh?!”

dawn.

Looking at the two Puff sisters sleeping in a kneeling position beside the bed, Ian felt much happier.

This should be considered as fulfilling the promise, right?

At this moment, there was a knock on the door.

The man walked behind the door and asked, "Who?"

"Senior, it's me!" Mashu's voice came.

"..."

Ian thought about it for a moment and then opened the door.

After seeing the appearance of the man in front of her and the "miserable condition" of the two Joans of Arc in the house, Mash immediately realized what had happened.

She was about to remind Ian of the wedding, but she lowered her head and said with a blushing face:

"Sorry...I didn't know Senpai was doing this kind of thing! I'll come back later!"

The pink-haired girl was about to leave when Ian grabbed her hand.

"Mashu, I really need you right now."

"..."

This was not the first time Mashu had heard the man say this, and of course she understood what he meant.

"……understood."

The pink-haired girl slowly knelt on the ground and began to clean up Ian gently.

She actually likes doing this kind of thing - because it makes her feel needed by the other person.

What she didn't know was that the man had already understood this.

of course.

Ian didn't just want Matthew to stay.

While enjoying her service, he used the device that could communicate with Chaldea.

Soon, Olga Marie's voice came from inside.

"Mashu?!"

"It's me, Chief."

"Eh?" Olga Marie's voice sounded a little surprised.

"Ian, you're not..."

"It's hard to explain." Ian went straight to the point. "Anyway, the Holy Grail of this singularity has been found."

"us--"

"I guess I'll be going back to Chaldea soon."

"Really?!" Olga Marie said excitedly, "Then I will go and prepare for quantum teleportation now!"

"No, Chief, not now."

"There are still some things that are not done."

"Wait for me to contact you later, then teleport."

"and--"

Ian glanced at his two "sisters" who were still sleeping soundly.

"I want to ask you a question."

"What's the problem?" Olga Marie responded.

"That is... if the singularity is repaired, will everything that happened during this period of time also disappear?"

"..."

Hearing this question, Olga Marie thought for a while before continuing:

"In theory, this is true. After all, history has returned to its original state."

"but--"

“There may be exceptions.”

"What does this mean?" Ian demanded.

"Well...let's put it this way." Olga Marie explained.

"One plus three equals four, and two plus two also equals four."

"The restoration of the singularity... ultimately only achieves a result of four. Many of the details are entirely possible to change."

"In extreme cases, it can even be broken down into 0.01 or even smaller values."

"As long as this result is not affected, there is a possibility of preservation."

"Maybe...it has something to do with the wishes of the person involved."

"Why are you asking this?"

"Nothing." Ian quickly ended the topic, "Director, I'll contact you later."

"Good~"

The contact was over and Mashu's cleanup was complete.

She wiped the corner of her mouth and whispered to Ian:

"Senior...it's all cleaned up."

"Yeah." Ian gently touched Matthew's head, "You've worked so hard."

"Next-"

"Just let me get the Holy Grail back... and put an end to all this."

A few hours later, inside the church of the Demon King's Castle.

The two Joans of Arc, wearing wedding dresses, held Ian's hands, one on the left and one on the right.

Even though their bellies were already filled with his fluid, they were similar yet different, and both felt happier because of this warmth.

Under the gaze of Fujimaru Ritsuka and his group, the three of them came before Gilles de Rey, who temporarily served as a witness.
