Anya, Nodoka and Yue going together to the public swimming pool in Mahora, because when they were at Tohsaka Resort they didn't have time to swim at all.
"It turns out in Japan a girl who have a big breast is very little than I thought," Anya said with a satisfied smile.
"Y-yes that's how it is," Nodoka said with sweat dripping down her cheeks as a reaction after she heard Anya's words.
"But there are also many who have jumbo-sized boobs, you know," Yue said who was wearing a dark purple swimsuit while making herself float on the surface of the water using a transparent floating board.
"But it's a very small in number, isn't it?" Asked Anya.
"More or less so," Yue replied. "Even if there are a lot of girls with big breasts, their breasts are fake because of it big from surgery desu."
Yue's answer made Anya somewhat confident, because at least the number of big-breasted girls in Japan wasn't as many as she thought.
But while she was feeling the pleasure of Yue's answer, Negi who was also going to the pool with the three of them experienced an incident that happened frequently in the harem protagonist's route.
"Humph!" Ehen Negi was swimming his head touched Chizuru boobs who came to the public swimming pool with Kotaro and Natsumi.
"Ara ara Negi-Sensei's head is stuck between my chest," Chizuru said who felt a little ticklish because Negi's head was pressed against her cleavage.
"I-I'm sorry Chizuru-san!" Negi said who quickly removed his head from Chizuru's chest. "I-I didn't see you at all!"
"Ara ara no problem Negi-Sensei," Chizuru said. "I didn't even know you were in this pool."
"It turns out that Negi is more attracted to girls with big breasts!" shouted Anya who looked very angry when she saw Negi's face touching Chizuru's chest. "Unforgivable!"
Anya then took out several bottles filled with a mysterious liquid out of nowhere and said:
"Uufufufufu this forbidden potion I made will make a girl's with a big chest feel sorry that they were born with a big boobs! If I put it in the water in this swimming pool!"
"Gyaaa Anya-san don't do that!" Nodoka shouted.
"Yeah stop doing that Anya-san!" Yue said while holding Anya's body together with Nodoka. "What you're doing is bio terrorism you know."
"Grrr if I can't flatten the chests of all the girls in this pool! Then the only way is to do the opposite!" Shouted Anya whose body was still tightly held by Nodoka and Yue.
"Eeeeeh the opposite?" Nodoka and Yue said who were confused by Anya's words, to the point that they let go of their grip on Anya's body.
"Ehehehehe my next forbidden potion can make all the chests of girls who drink it grow big!" Anya said laughing in a sinister tone. "And the best thing is the effect is permanent! Ahahahahaha!"
Anya once again took out a potion bottle out of nowhere then gave one bottle each to Yue and Nodoka.
Nodoka and Yue swallowed their saliva, when they saw the bottle of breast enlargement potion that Anya had given them. Both of them wanted the ideal bust size, but they felt a bit doubtful about the effect of Anya's potion. Even Anya herself looked confused whether she wanted to drink the potion she made or not.
Until Nodoka and Yue saw Rin and Shirou sitting under a big umbrella, Shirou was sleeping on Rin's lap and Rin was playing with Shirou's hair while looking at Shirou's face. Nodoka and Yue immediately had the same idea in their heads which was to make Rin the guinea pig from Anya's mysterious potion. Rin has a small chest, so Nodoka and Yue think that Rin is the most suitable guinea pig for Anya's strange potion.
Yue walked up to Rin and greeted her while offering Rin the bottle containing Anya's potion.
"Eh, Tohsaka-san I saw you earlier, and it looks like you look thirsty. Would you like to drink the fresh water in this bottle?" Yue said.
"Eh, ah Yuechii what's wrong with you, suddenly offered me a drink like this?" Rin asked who felt a bit confused why Yue suddenly offered her a drink.
"Can't I give drinking water to my friend who looks thirsty?" Yue replied.
"Well, I guess that's not wrong either," Rin said as she took the bottle containing Anya's mysterious potion from Yue's hand.
Rin then drank the potion in the bottle until it was finished, and after the bottle was empty Rin returned the bottle to Yue saying:
."Aaah what a refreshing drink! Thank you Yuechii you really helped me by bringing that drink!"
"N-it's okay I'm glad I could help you Tohsaka-san," Yue said with a somewhat forced smile.
Yue was relieved to see that the taste of Anya's potion was not strange and seemed to be refreshing instead, she walked away from Rin and returned to where Nodoka was waiting.
"I've managed to get Rin-san to drink Anya-san's potion, now we just have to wait for the effect to work," Yue said.
"That's good then," Nodoka said. "Even though I feel guilty towards Rin-san but I don't want to drink strange potions whose effects haven't been tested yet!"
"I guarantee that my potion is effective!" Anya said who was a bit offended by Nodoka's words. "In theory this potion of mine can make any girl's breasts grow big instantly! Even though I've never tested it myself!"
"Then why isn't Rin-san's chest enlarged yet?" Asked Yue while pointing at Rin.
"Hmm this is really weird," Replied Anya while looking "The potion should work right away, did I enter the wrong ingredients?"
Sensing that the potion wasn't working, Anya then removed the potion in an instant in front of Yue and Nodoka just like she had let it out in empty air.
Yue and Anya were amazed by what Anya was doing, they were wondering how Anya could remove objects and bring up objects in an instant even though she wasn't wearing her magic robe or carrying a magic bag.
"Sigh! I have to re-research the potion earlier!" Anya said who was disappointed because the potion didn't work. "Even though I used all my savings to make the potion."
"A-A-Anya-san how do you can make a thing suddenly appear and disappear like that in a thin air desu?" Yue said nervously. "I'm really curious desu!"
"Y-Yeah, me too," Nodoka said.
"What I did earlier was the basic magic taught at the magic school where Negi and I studied," Anya explained. "The name of the magic is Item Box, I like to use it because it's practical but the old-fashioned Negi prefers to use luggage and bags rarely use them and he only uses them to store things he deems very important."
"Item Boxes like those in RPG games?" Asked Yue.
"Well, you could say so," replied Anya. "It seems that the creator of this magic really likes RPG games and the like, the creator of this magic is the mysterious sorceres name Zelretch."
"Th-then can you teach it to us?" Asked Nodoka.
"Sure," Answered Anya. "But this magic is not easy to learn, even a genius like Negi took 1 year to learn it because he has to understand the basic of space and time magic. Are you sure that you two still want to learn it?"
They both nodded their heads, because both of them magic like that was very useful to learn. Even if it takes a long time.

That night at Emiya's residence, Rin who was lying next to Shirou felt something strange in her bobs. Both of her boobs felt itchy and became very hot, Rin who can stand the hotness on her boobs immediately ran to the bathroom in the room to cool down her boobs.
Rin took off the pajamas she was wearing and then she washed her boobs using the wet towel she soaked in the water. After Rin felt better, she then looked at the condition of her boobs in front of the mirror and what she saw in the mirror shocked her beyond measure, Rin's breast size, which was neither small nor large, suddenly swelled beyond the size of Chizuru's boobs. Who had the largest boobs in class 3-a.
"This is really ridiculous how did my boobs can became so big!" Rin said. "Am I having a growth spurt?"
Rin who usually could analyze various strange situations quickly and correctly this time couldn't do that because she was confused, so she didn't think that the strange drink she got from Yue was the cause of her condition right now....
