"Ohohohohoho! Look at me Sherou! Look at this display of power! More useful than Ishtar, right?" Astraea exclaimed in excitement.

Shirou sighed as he looked at Luvia, or rather Astraea, take down hordes of enemies with her power as he slashed another enemy with his katana. As he continued slashing his enemies, a few thoughts came to his mind.

One which involves the butler outfit he was wearing currently.

And the other was the situation he was in.

"How did I end up in this situation?" he thought as his mind wandered to what happened a few hours ago...

(A few hours ago...)

"You're asking me to pair up with Astraea for a day?" Shirou asked Da Vinci and Ritsuka.

"Yes," both of them said in unison.

"But why?"

Da Vinci let out a sigh. "Honestly, it's because of your interactions with the other servants, and for some reason, she's not happy about it."

Shirou was flabbergasted at Da Vinci's explanation.

"Yeah. In fact, there were a few cases where she got into fights with Ishtar and her rider self after finding out that they spent time with you, and those fights well...they were too explosive even by Chaldea's standards. So, we asked her how to calm her down, and well..." Ritsuka said but was cut off from Shirou.

"In order to calm her down, you asked me to be with her for a day correct?"

"Yes. That is correct. She asked us if you can be with her for a day," Ritsuka said.

Shirou sighed. "Well...I can't refuse, can I?" Ritsuka and Da Vinci nodded, making Shirou sigh again. After a few moments of silence, he said, "Okay. I'll do it."

Ritsuka and Da Vinci smiled as they were glad as they were finally able to get some peace once from those three. Shirou was about to leave before Ritsuka placed a hand on his shoulder.

"Wait. There's one more thing I need to mention..." Ritsuka said.

Shirou was confused as he turned around...to see Da Vinci holding a familiar butler mystic code.

"Apparently Astraea also wants you to wear this butler mystic code from earlier," Da Vinci said with a smile.

Shirou sighed again.

(Back to the present...)

"Man, can't believe I'm wearing the butler mystic code again...and in a battle of all places. At least Da Vinci did make it stain-proof, so I won't worry about it getting dirty later...but still...this is the first time I've ever done something with Luvia...it could be nice." Shirou thought as he slashed another enemy down.

Meanwhile, Astraea was having the time of her life. After all, weeks of not spending any time with Shirou has resulted in a huge amount of pent-up jealously and rage.

Especially at the Arturias, Rins, Sakuras, Illyas, and the Knights of the Round.

And now after talking with Ritsuka and Da Vinci, she finally got her wish.

Spending time with Shirou.

"Man, I can't believe that my recent tussle with that useless goddess has created an opportunity like this! A day of having Sherou to myself! Might as well thank master later when this is over..." she thought as she kicked an enemy to the ground. As she began to swing her sword against another, she was so drowned in the feeling of fighting alongside Shirou that she didn't notice another enemy coming up behind her.

Luckily, Shirou managed to save her by tracing a copy of Kanshou and Bakuya and threw at her attacker's face, instantly killing him.

"Are you okay Astraea?" he asked.

Astraea blushed for a moment before answering, "Yes Sherou!"

Shirou smiled. "Well that's a relief. I didn't want to see you get hurt. Now come on, we've got a mission to finish."

Astraea nodded and soon the two left the area. As the two were walking in the forest, Astraea was having multiple thoughts in her head. "Oh my god, I nearly embarrassed myself in front of Sherou for a moment! Get a hold of yourself Astraea! Don't let yourself get into a bad situation again!" she thought as she and Shirou were walking down a trail path.

Shirou noticed this and asked, "Are you okay Astraea-san?"

"Yes. Why Sherou?" Astraea replied.

"Because your face is red."

Astraea then grabbed her scales and used it as a mirror to see her reflection. As such, Shirou was right. Her face was red like a tomato. Astraea then quickly regained her composure and said, "It's nothing Sherou."

"I see..."

"Also, you don't have to call me Astraea. Luvia is fine Sherou."

"Is that so? Then, shall we move on Luvia?"

Astraea smiled. "Yes Sherou!"

And so, the two continued finishing their quest.

(A few hours later...)

"And...they're back!" Da Vinci exclaimed as Shirou, Ritsuka, and Astraea were rayshifted back to Chaldea. "How did the mission go?"

"Well..."Shirou tried to explain but was cut off from Astraea.

"It was wonderful! Me and Sherou were taking down enemy after enemy with such divine grace and beauty!" Luvia boasted. "Oh, you should have seen it! It was glorious!"

Both Ritsuka and Da Vinci looked at Shirou in question after hearing Astraea's explanation. "Yeah. It went well..." he said while being embarrassed from hearing such praise from Astraea.

"Yeah. I agree with Shirou and Astraea," Ritsuka said.

"I see..." Da Vinci said. "Well anyways, all three of you can leave now."

Shirou, Ritsuka, and Astraea thanked Da Vinci and left the summoning room. However, as they got out of the summoning room, Astraea then grabbed Shirou's arm and dragged him to one direction of Chaldea's hallway.

"Wah! Luvia, where are we going?!" Shirou yelled as he was dragged across the hallway.

"Isn't it obvious?! I'm taking you to one of Chaldea's shops!"

Shirou was surprised. "Since when did Chaldea have shops?!" he asked.

"For a while now! You just haven't seen them yet!"

As Astraea was dragging Shirou in the hallway, she caught the attention of the Rin-faces and Sakura-faces, prompting jealously from them.

"Hey! What are you doing to Emiya-kun, Astraea!?" Ishtar, her rider self, and surprisingly Ereshkigal yelled out.

"It's none of your business you useless goddesses!" she yelled out to Ishtar and her rider self.

"Let go of senpai this instant!" Parvati, BB, Passionlip, and Meltlilith said while Kingprotea and Kama stayed quiet, but still showed jealously.

"Nope! He's mine for today!"

And just like that, Astraea instantly increased her running speed just to make sure that the Rin-faces and Sakura-faces don't try to follow her.

After a few minutes, Astraea finally arrived at the area filled with shops along side with Shirou. As Shirou managed to catch his breath after being dragged around like a rag doll by Astraea, he was shocked at the amount of shops that were inside of Chaldea. There were multiple shops of many interests. Some shops were selling jewelry, others were selling weapons, others were selling books, and many more.

And it piqued Shirou's interest.

"There was something like this in Chaldea?" Shirou asked Astraea.

"Yes Sherou! Chaldea is filled with shops of many things! Not only that, but it also has hot springs, a simulator, and many more things as well!" Astraea explained excitedly. "Now come on! There's a lot of shops that I want to show you!"

Astraea then started dragging Shirou around the many shops. The first one they stopped by was a jewelry shop. As they went inside, they were greeted with multiple jewels everywhere, ranging from small to big in many colors. Astraea then looked around to see which jewel suits her best but was having trouble choosing which one.

She then turned to Shirou and asked, "Sherou, which jewel do you think that suits me?"

Shirou looked at all of them and replied, "I don't know. They all look beautiful to me." Astraea sighed at Shirou's answer and continued to look around the counter for any jewelry that suits her. As they looked around, Shirou saw one that caught his attention. It was a necklace which was a sapphire gem shaped as a diamond with gold patterns engraved on the sides being held up by a gold chain. "How about this one?" he asked as he pointed at the necklace, letting Astraea see.

As Astraea saw it, she was immediately entranced by its beauty. "It's perfect Sherou!" she exclaimed happily. "I'll take it!" she said before buying the necklace. As she received the box that has the necklace, she then opened the box, pulled out the necklace, and said, "Sherou, would you mind helping me putting the necklace on my neck?"

"Are you sure?"

"Yes. Please."

"As you wish Luvia," Shirou said before he took the necklace from the box and wrapped it around her neck carefully.

As Shirou was done with the task, Astraea turned around and asked, "How do I look Sherou?"

Shirou gave her a smile. "It looks good on you."

Astraea blushed at Shirou's complement before quickly regaining her composure. "Come on, we got another store to look at!" she exclaimed as she was walking out the jewelry store. Shirou then followed her out.

After a few minutes, they stopped by the next store, which was a mystic code store.

Which looked like a regular clothing store.

Astraea and Shirou then went inside the mystic code store. As they went inside, the inside of the store was filled with mystic codes that looked like clothes made by top designers. As so, Astraea was excited trying out the multiple mystic codes as she picked out multiple mystic codes.

"Sherou, I'm going into the dressing room for a moment. Would you be a dear and wait for me?"

"Sure."

Astraea then went into the dressing room and Shirou waited for her. "I wonder why did Rin, Sakura, and their alternative selves had a problem while seeing Luvia dragging me around? Did she do something bad to them?" he thought as time passed by.

Eventually, the curtain to the dressing opened, revealing Astraea in a familiar outfit Shirou thought he would never see again.

It was Luvia's old dress.

"Well Sheoru, how do I look in this dress?"

Shirou smiled. "It looks great on you Miss Luvia."

Astraea smiled back at him. "Glad that you liked it!" she said excitedly.

As the day went on, Astraea tried on a multitude of dresses, and Shirou said she looked good in all of them. Eventually, Astraea went through all the dresses/mystic codes she brought over and bought them all.

(A few hours later...)

"Well, wasn't today a fun day Sherou?" Astraea asked with a smile as they were sitting at a table of a nearby café. After many hours off shopping from other stores followed up by Shirou and Astraea carrying the large number of gifts that came with the shopping, they found a nearby café for a small break.

As Shirou and Luvia were waiting at the table, Shirou noticed the large number of gifts next to Luvia. "Wow. We spent quite a lot today..." Shirou thought as they were waiting for the sweets they ordered.

"Hey Sherou, can I ask you something?" Astraea asked, snapping Shirou out of his trance.

"Hm? Oh sure. What is it?" Shirou replied.

"What do you think of today?"

"Today? Well...it was quite fun actually."

"You think so?"

"Yeah," Shirou said with a smile.

"I see..." Astraea muttered with a blush.

Shirou noticed Astraea's behavior and asked, "Are you okay Luvia? You seem to be quite red."

"Eh?! Oh! It's nothing!" Astraea embarrassingly said.

It was then that the waiter arrived with the sweets they ordered. As they ate, they also had a few chats as well in which some included the earlier events as well as the items they bought as well. Soon, they were finished with the deserts and the waiter came and took the empty plates away.

"Well then...shall we pay up?" Shirou asked.

"W-Wait. There's one more thing that I want to do," Astraea said in embarrassment.

"Well okay. What is it?"

Astraea then pulled a small red box from one of the bags from earlier. She then opened the box up, revealing a small bracelet made out of metal and there was a red jewel in the middle with silver markings.

"This is for you Sherou," Astraea said proudly.

Shirou was in awe of the gift Astraea was about give him. "Are you sure? I mean, don't you want it?"

"Yes. I want you to have this. If anything, this accessory suits you the best, probably even more than me."

Shirou blushed after hearing Astraea's words. "Well...if that's the case...then I accept your gift Luvia," he said with a smile.

Astraea blushed at Shirou's words. Shirou then took the bracelet from the box and placed it on unclothed arm. "How does it look Sherou?" Astraea asked.

Shirou took a quick look at it and said, "It looks great Luvia," with a smile on his face.

Astraea beamed with excitement. "Really?!"

"Yes."

"Well then...I'm glad you like it Sherou!" Astraea said in happiness.

"You're welcome," Shirou said. "Now then...shall we move on then?"

"Yes!"

And Shirou and Astraea continued their day together...
