In the world of Type-Moon, it all begins with becoming Morgan's husband!

A few minutes later.

Ian and Olga Marie said their goodbyes in a tender atmosphere.

Next, he prepared to return to his room, but unexpectedly received a message from Mashu.

It turned out to be the shameful picture he had sent her earlier, covered in tally marks.

【Mash】: Senpai... you haven't drawn that line in the conference hall yet.

Ian paused for a moment.

He's been so busy lately that he's forgotten all the rules he set for Mashu's upbringing.

But she remembered it very clearly.

She's such a simple girl.

Ian: ...

[Ian]: Mash, where are you?

Following the directions given by Mash, Ian arrived at a passageway in Chaldea.

The lights were not turned on here due to insufficient power supply.

If Mashu's phone hadn't been lit up, Ian felt he wouldn't have been able to find her at all.

At this moment, the pink-haired girl had removed her Servant armor and changed back into her usual Chaldea uniform.

Full of youthful energy, she stared intently at her phone, looking as if she was eagerly anticipating someone's arrival.

Seeing this, Ian smiled and said.

"Mash, I'm here."

Upon hearing the familiar voice, Mashu immediately looked up and then spotted the person she had been longing for.

"Senior~"

The pink-haired girl ran over and buried herself in his arms.

"You came!"

"Have you been waiting for a long time?"

“No, that’s not true!” Mashu shook her head. “I just arrived myself!”

That's not actually the case.

Ian guessed that Mash was already waiting here when she sent him the message.

She never makes anyone wait for her.

However, Ian did not intend to expose him.

"Senior."

Mashu took out a pen and, with a shy yet unwavering expression, handed it to the man in front of her.

"I have prepared everything that needs to be done."

"Shall we start now? Or should we wait a bit?"

"..."

Ian took the pen from Mashu's hand and realized it was the same one he had used before. He put it in his pocket.

The man reached out and patted the girl's head.

"Mash, you don't need to draw anymore... You should also wash away those marks from before."

"Eh?!"

Mashu looked at Ian with a worried expression.

"Why? Did I do something wrong that offended the senior?"

"No, Mashu, you did a great job."

"Then how..."

Ian smiled slightly: "Because Mash, your identity has changed."

"You are no longer my 'tool,' but my girlfriend."

"so--"

“What I did to ‘tools’ in the past, I can no longer do to you.”

"senior……"

Mashu's purple eyes were filled with joy.

She smiled sweetly.

"Oh right... I'm your girlfriend now."

But then she suddenly remembered something.

"That--"

"So, in that case, you don't plan to give me the qualifications to do those things anymore?"

"Ahem." Ian cleared his throat.

"No, that's not true... girlfriends can do that too."

“I see.” Mashu breathed a sigh of relief. “I thought you were starting to dislike me because you thought I was clumsy.”

"..."

"..."

Since the explosion, Mash has indeed not looked at Ian like she used to for a long time.

Her cheeks flushed slightly, and she began to stammer as she spoke.

"Senior...may I use my girlfriend's privileges a little now?"

“Of course you can.” The man’s finger lightly traced across Mashu’s lips.

At the same moment, in the shadows of the corridor.

Using the light from the cell phone screen on the ground not far away, Mordred stared in disbelief at the scene before him.

What is Father doing?!

What is Mashu doing now?!

What on earth are those two doing there?!

Is this some kind of weird way of communicating?!

Mordred, who had zero experience, blushed with embarrassment, but couldn't understand at all what her father and Mash were doing at that moment.

But her intuition told her that Mash's actual intimacy with her father was no less than that with Olga Marie.

Olga Marie was her father's girlfriend;

Is Mashu also my father's girlfriend?!

Including Fujimaru Ritsuka, who was previously talking about a "heroic couple".

That makes three!

My own father has three girlfriends in Chaldea?!

Just how many women has he seduced?!

Can you count them all on your ten fingers?!

Mordred felt her mind go blank, even forgetting about the Gawain mashed potatoes she hated most.

As the man exhaled a breath of warm air, Mashu stood up shyly.

"Senior...you are as energetic as ever, that's wonderful."

"Thank you for your hard work, Mashu."

"That's not true." The pink-haired girl looked at the man in front of her with lingering affection.

"It would be great to be able to relieve some pressure for my seniors."

"By the way... has Senpai and Ritsuka become boyfriend and girlfriend?"

"...So be it."

"Understood!" Mashu nodded seriously after confirming. "I will get along well with her, so don't worry about our relationship, Senpai!"

That would be wonderful.

"Hmm~"

Mashu carefully spoke, carrying the double on her back.

"Well... I'll be going now~"

"See you when we set off, senior!"

"it is good."

Mashu recalled everything that had just happened and felt satisfied.

At this moment, she planned to return to her room as soon as possible to prepare for the next move.

You absolutely must work hard, and protect the people around you, so as not to cause trouble for his family.

This is the only thing I, as the Shield Heroic Spirit, am good at right now!

But at this moment——

"Stop!"

A shout came to stop them.

Mordred, now recovered, leaped out of the shadows where she had been hiding.

She anxiously stopped Mashu from leaving.
