Hello, everyone! Last time, Mikoto and Touma spent their first real night together. This time, they continue their vacation.

GG Vegito: Yeah, Mikoto had a lot of guts inviting Touma into bed with her.

comrade-elmo1: Yes, indeed, Touma will like her breasts no matter their size.

Toa Solaric: Mikoto did trust him and open up about her insecurity, and he successfully reassured her about it.

bitbitbit11: Thanks, I'm glad you enjoyed the fluff. Some interesting things will definitely go down when they run into Shokuhou.

Blankow: Yeah, there are quite a few significant developments in the past chapter. They should be safe from people spying on them in their hotel room, but their friends might learn about them sharing a bed in other ways.

Stryper88: It was more of a relaxing massage than an erotic one, which is why she didn't make those kinds of noises. Touma had to try hard to now start fantasizing about taking a shower with Mikoto. I'm glad you enjoyed the ring part, I tried to make it as romantic as I could. You're right, I did want him to reassure her and tell her that the rest of her body is also attractive. Seeing each other naked is probably one of the last remaining steps. They will definitely need to have a discussion about Baggage City. Once both of them are back in Academy City, they'll certainly have lots of opportunities to interact with the Railgang. If Shokuhou notices the ring on either of them, that'll definitely raise some suspicions. I do have a few more ideas for slice-of-life chapters thanks to that thread, and their fathers calling them is definitely an interesting idea.

DBZLEGEND154: Welcome back! Yeah, Mikoto did get to comfort him a bit this time about Birdway's betrayal. Touma is a very loyal and supportive boyfriend indeed. I did want to feature the rings heavily in my fic. I hope they appear again in canon, but I'm not that hopeful for it. Though GT4 seems to have Mikoto's Gekota strap appear again, so maybe there is some hope.

MC91: Thanks, I'm glad you enjoyed all the fluff.

DarkMatter69: I'm not sure I agree that Touma and Othinus' relationship is beyond lovers in canon, even if they call each other their understander. But certainly in this fic, Touma's relationship with Mikoto will not be overshadowed by his relationship with Othinus.

Bigboy101: I'm happy you enjoyed Mikoto being sweet and embarrassed in this chapter, and how Touma helped her with her insecurities.

Guest: Yeah, they're steadily progressing in their relationship. Having a fanmanga or even just some art with some of the scenes from this fic would be amazing!

guest: I'm glad you're continuing to enjoy the story. I'll keep trying to release about one chapter per week.

MarauderPrime12: Thanks, I'm happy you enjoyed it.

Guest10032: I hope you did well on your AP tests so far, and good luck on any of your future ones. Mikoto definitely wants to take full advantage of this golden opportunity. Mikoto's interaction with Othinus will certainly be interesting. I think they could get along quite well, once Mikoto is able to look past her torturing her boyfriend for billions of years.

xellos540: Yeah, "A Certain Infinite Possibility" is a really great fic! I didn't want to spoil things too early by having just one bed. Two people sleeping in a bathtub would probably be too cramped. I got inspiration for the mutual hair drying from the "Flirting Railgun" doujin, and added a few extra things to it. Mikoto is indeed getting bolder, and they're both feeling cozy with each other. Those are very scheming characters. Yeah, it's a bit awkward, but I think he can't remember her name, so he'll just think of her as Mikoto's classmate. It did seem like a proposal, didn't it? I found the light interference explanation pretty interesting, which is why I included it. Worst is definitely a troll who likes mocking Mikoto. I did try to make Touma's response corny but also romantic. Mikoto probably expected him to at least ask instead of immediately going for the other bed. Yeah, Mikoto needed to be the one embracing him for the plot, but it also kind of makes sense since she was the one who invited him into bed with her. Touma didn't expect her small breasts to be as soft as they were. Yeah, "ass" is a bit crude, but "butt" sounds a bit awkward to me. I used "midriff" because it includes both the waist and stomach. Kinuhata was the one Mikoto teamed up with to find the Bust-Upper. Mikoto was basically using it as an excuse to get him to rub them. And they finally fell asleep in each other's arms. We're not quite returning to the action yet, since this new chapter will continue showing their Hawaiian vacation.

The following morning, as Touma woke up and opened his eyes, he saw that his girlfriend was now snuggled into his chest, while his arms were still on her back and in her hair. He lovingly gazed at Mikoto's sleeping face, which had a content smile on it. He thought to himself, "She looks so cute and peaceful when she's sleeping!"

However, the boy was soon startled when Mikoto suddenly began speaking, still with her eyes closed, "Mmm, Touma…" His eyes widened at her saying his name in a flirty tone. Touma knew she was still asleep, but that didn't stop him from blushing when she danced her fingers along his chest and continued in the same alluring tone, "I got you now, and you can't escape from me! So, what shall I do with you first?"

Touma then replied, "Mikoto?" While stroking her hair, he wondered, "What kind of dream is she having?" He noticed that she was not at all flustered, and he felt both anxious and intrigued at the prospect of her being like that when awake.

Mikoto then smiled in her sleep and said in a more normal tone, "I love you, Touma."

The boy was a bit surprised at her sudden change in tone, but he smiled and said back to her, "I love you too, Biri-Biri." He then pressed a gentle kiss to her forehead.

After this, the girl began stirring and slowly opened her eyes. As she realized her position in her boyfriend's arms, she blushed and said in a sleepy tone, "Good morning."

Touma gave her a quick peck on the lips and said, "Good morning, Mikoto!" He then grinned and asked, "So, what exactly were you dreaming about?"

Mikoto was a bit confused and replied, "Hmm, I don't really remember. Why do you ask?"

The boy chuckled and revealed, "Well, you were actually talking in your sleep, saying something about me not being able to escape and deciding what to do to me first. That sounded like a pretty naughty dream!"

The girl's eyes widened in shock, "W-wait, I talk in my sleep?" Realizing that she must have been having a heated dream, Mikoto suddenly turned aways from Touma in embarrassment and covered her face with her hands.

Touma chuckled, wrapped his arms around her waist, and pulled her tighter against him. He then wondered, "You didn't know that? If you do that often, Shirai-san has probably heard you a bunch of times. I'm surprised she hasn't told you."

Mikoto's face reddened even more as she concluded, "Oh nooo, Kuroko's probably heard all my weird dreams!" She'd had a lot of dreams about Touma, even before they'd started dating, and knowing that Kuroko had potentially heard many of those dreams made her want to shrink into a ball.

Touma caressed her waist with his thumbs and tried reassuring her, "Come on, it's not that big of a deal. Everyone has dreams like that sometimes, right? She probably just didn't want to embarrass you." He added said in a joking tone, "That or she made recordings of your voice so she could listen to them later in secret."

Mikoto finally brought her hands down and sighed, "I know you're joking, but that sounds like something she would actually do. But she's stopped obsessing over me like that recently, so I hope she isn't keeping a secret stash of recordings."

The boy chuckled and said, "I hope so too." He then nuzzled his face into her hair and asked, "Well, anyway, what do you want to do today? We have the entire day to ourselves!"

The girl placed her hands over her boyfriend's and intertwined their fingers, before suggesting, "Hmm, we should definitely go to the beach. And I wouldn't mind doing some shopping too!"

Touma replied, "The beach sounds fun, but I'm not sure about the shopping. Are you going to drag me around for hours trying on clothes?" He didn't want to suffer the fate of the guy on a stereotypical shopping trip with his girlfriend.

Mikoto rolled her eyes and retorted, "Don't worry, I'll probably only look at a few outfits anyway."

The boy smiled, "All right, I guess I can endure it for a bit to see you in some cute outfits!" Plus, if they went to the beach, he'd get to see her in a swimsuit! That was definitely something for him to look forward to.

After cuddling for a bit longer, they finally decided to get up. After brushing their teeth, they sat back down on the bed, and Touma turned on the TV to a news channel. They were talking about Trident's attack on Pearl Harbor the previous day, which had resulted in the destruction of multiple warships. Mikoto observed, "Looks like we won't be able to visit Pearl Harbor, unfortunately. It'll take some time to recover from all that damage."

The news then went on to mention that the battleship USS Missouri was spared in the attack. Touma mused in a skeptical tone, "I'm surprised they left a battleship alone and went after the smaller ships."

Mikoto noted, "Well, that battleship is very obsolete. It's from World War 2, and it's just used as a museum ship now, since it's where Japan officially surrendered. The modern Aegis cruisers and destroyers were much more valuable targets."

Touma nodded in understanding, "I see. A lot of those Aegis ships were destroyed, so this must be a big blow to the US Navy."

Mikoto shrugged her shoulders and replied, "Well, the Americans have almost a hundred of those ships, so they can recover from this. Plus, they still have all ten of their aircraft carriers." As a result, just like with the original Pearl Harbor attack, the US Navy wouldn't be crippled by this attack.

The boy smiled, "That's good, I suppose." He was glad that at least GREMLIN wasn't able to destabilize the United States completely.

Mikoto then stretched out her arms and legs, before hopping off the bed and digging into her luggage. Pulling out some clothes, she said to her boyfriend, "Hey, can you turn around so I can change?"

Touma said, "Okay." He turned around on the bed, a bit surprised she wasn't going into the bathroom to change, but he supposed it was more convenient.

The girl was facing away from him, but looked back at Touma and exclaimed, "You better not peek!"

Touma covered his eyes with his hands just to be sure there wouldn't be an unfortunate accident, and replied, "I won't!" He certainly wouldn't mind having a peek, but only if she was comfortable with it.

Mikoto then took off her pajamas and changed into a t-shirt and shorts. Once she was done, she announced, "Okay, you can turn back around now." As Touma looked at her again, she sat back down on the bed next to him.

The boy thought she looked nice in that casual wear. He then went over and pulled out some clothes from his own luggage. Mikoto turned around and faced away from him, and he also changed into a t-shirt and shorts.

Now that they were both ready, Touma suggested, "Shall we go get breakfast?" Their hotel room came with a free breakfast, so he was eager to take advantage of it.

Mikoto nodded, "Yeah, let's go!" They then left the room, eager to eat a warm meal before going out for the day.

After breakfast, Mikoto and Touma were now in a clothing store at the Coral Street Shopping Mall. Although it had been the site of a battle the previous day, it was now open for business like normal.

Mikoto had just picked out some clothes, and they were headed towards the dressing rooms so she could try them on. Touma asked her, "When are you going to wear all these clothes anyway? You have to wear your uniform all the time back in Academy City, right?"

The girl gave him a grin and answered, "That's true, but I can wear them when I'm outside the city, or even when I'm sneaking over to your place!" Indeed, she had already worn other clothes multiple times in those kinds of circumstances.

Touma laughed and replied, "Good point. And it's nice to see you in different outfits!" Mikoto then walked into one of the dressing rooms, and he sat down on a bench just outside, patiently waiting for her to show off for him.

After a few minutes, he saw Mikoto walking towards him, wearing a red Hawaiian sundress and carrying some more clothes in her arms. He was about to greet her, but he noticed that something was off about her. She'd walked from outside the dressing room area, which was odd, since Mikoto was supposed to be inside one of the dressing rooms. In addition, she wasn't wearing either of her usual hair clips. Instead of two small flowers and a lightning bolt with an M, the girl had a single larger flower in her hair. But the most telling thing was that her demeanor was quite different from his girlfriend's, so Touma was able to deduce, "You're one of Mikoto's sisters, aren't you?"

"Yes, your deduction is correct, says Misaka, quite surprised that you were able to tell her apart from Big Sister so quickly. Misaka's serial number is 13650, adds Misaka for clarification."

Touma thought back to his penalty game with Mikoto in the underground mall, where a similar thing had happened with Misaka 10032, but that time, he'd only realized the truth when he'd heard Mikoto shouting from far away. He smiled at the girl in front of him and said, "Nice to meet you, 13650-chan! Yeah, I know Mikoto a lot better now, so it's easier for me to tell the difference. Plus, you're wearing a different hair clip, and I don't think that dress was one of the ones that she picked to try on."

Misaka 13650 brought up a hand to gently touch the flower in her hair. "It's nice to finally meet you too. Misaka is glad you noticed her unique accessory, and this dress is one that already belongs to her." She then set down the clothes she was carrying on the bench next to him. "How do you think Misaka looks in this dress, asks Misaka, giving you a twirl so you can see it from every angle."

The boy stared at her as she twirled around, his eyes drawn to how the edge of the dress lifted up and showed off more of her legs. Once she stopped to look at him again, he told her, "You look very pretty, 13650-chan!"

"Thank you, shyly says Misaka, blushing at your compliment."

At this point, Mikoto returned from the dressing room, wearing a red Hawaiian shirt and a pair of blue shorts. Her eyes widened as she saw one of her sisters, and she asked, "Hey, are you shopping here too?"

"Hello, Big Sister. Yes, Misaka is also doing some clothes shopping here, confirms Misaka. As she just told the boy, her serial number is 13650."

Mikoto nodded and greeted her sister, "Well, hello 13650-chan!" She then turned to her boyfriend and asked, "So, how do I look in this, Touma?"

Touma looked her up and down and said, "You look really cute in that!"

Mikoto looked down at her outfit and smiled, replying, "Thanks! I'm not sure if this is really my style, but I wanted to try out the Hawaiian shirt. I guess I'll buy them." Maybe she wouldn't wear it too often, but it would at least remind her of her visit to Hawaii.

Mikoto wanted to talk to her sister about a sensitive subject, so she used her ability to jam all the nearby cameras. She then turned to Misaka 13650 and asked in a low voice, "Hey, so are the Sisters at those defecting institutions okay?" This group of institutions already had access to some of Academy City's advanced technology, but if they were able to capture even one of the clones, that would be even more catastrophic.

"Don't worry, Big Sister. All those Misakas were able to escape and destroy all physical and electronic data, including our DNA maps, reports Misaka. Thanks to the Misaka Network, they were able to do this immediately and simultaneously, before the institutions could take action, elaborates Misaka, hoping to reassure you that all of them are safe. Also, Misaka's own institution, being American, is grateful for Academy City's help during the invasion yesterday, so her situation is not in peril, adds Misaka to clarify her own status."

Mikoto sighed in relief, "Thank goodness!" Once again, she was impressed by her Sisters' battle tactics and their ability to act quickly.

"It seems you've given the boy that ring, says Misaka as she eyes the rings on both of your left ring fingers and recalls a particular memory from the evil one."

Touma smiled, playing with his ring, and replied, "Yeah, I was very surprised at first, but it was actually a very thoughtful present. She even colored it with her electricity!"

Mikoto fidgeted with her ring and smiled at him, once again grateful that he'd accepted her gift. Meanwhile, her sister had picked the clothes she wanted to try on back up from the bench, so Mikoto grabbed her hand and pulled her towards a dressing room, exclaiming, "All right, let's try on some more clothes!"

"All right, assents Misaka, allowing herself to be dragged along, and eager to model for the boy."

Touma chuckled at their antics as they disappeared behind the curtain. This shopping trip was turning out to be a lot more fun than he'd feared at first.

After another few minutes, both Misaka sisters reappeared in front of him. Misaka 13650 was now wearing another Hawaiian sundress, this time blue, while Mikoto was wearing a gray shirt and a black skirt. Mikoto smiled at him and questioned, "So, how do we look?"

The boy looked over both of them and commented, "You look pretty in that too, 13650-chan! I think that blue really suits you. And Biri-Biri, those colors suit you well, you look stunning!" He blushed a little as he stared at his girlfriend, who looked especially attractive in that outfit.

Mikoto blushed as well, due to his compliment and his obvious staring. She replied, G-great, I guess I'll buy these too!"

"Misaka is happy about your praise. She figured that blue would complement her eyes and hair, says Misaka, explaining her choice."

Mikoto nodded and mused, "Yeah, blue is a very good color for us." That gave her an idea as she recalled the last items she and her sister were about to try on. She pulled Misaka 13650 back into the dressing room. To prevent Touma from hearing her, she leaned in close and whispered, "Hey, so we both picked out the same blue dress to try on, right?"

"That appears to be correct, whispers Misaka, wondering what the need for covertness is."

Mikoto smirked and proposed her idea, "When we put them on and come out, let's not talk at all and make him guess which one of us is which!"

"Misaka likes that idea, says Misaka, mirroring your smirk. But we must make sure to remove our hair clips, and you should hide your ring, notes Misaka, wanting to make sure we look as identical as possible for this plan."

Mikoto nodded, "Yes, we should." Both of them proceeded to wear the identical blue dresses. They took off their hair clips and stepped out of the dressing room. As they approached Touma, they both made sure to hide their hands behind their backs.

Touma's eyes widened at the sight of the identically-dressed girls. The dresses were rather short, only going down to mid-thigh, and their shoulders were exposed. His cheeks reddened, and he commented, "Wow, both of you look absolutely gorgeous!"

Both girls smiled and blushed, but neither of them said anything. After a few seconds of silence, Touma tilted his head in confusion and said, "Guys?" They still didn't say a word, and he noticed that they'd taken off all their hair clips. He soon guessed, "Do you want me to try figuring out which one of you is which?" They both nodded in response, so Touma looked more carefully at the two girls.

Although Mikoto and Misaka 13650 looked exactly the same, they did have slightly different mannerisms, even when they were standing still like this. After studying them for a few seconds, he was pretty sure he knew which one was which. He walked towards one of the girls, gently grabbed onto her bare shoulders, and kissed her.

They both closed their eyes and kissed for a few seconds. When they pulled apart, the girl asked, "How were you so sure it was me?" Indeed, he had picked correctly.

Touma smirked, "Come on, I'm pretty used to how you act now." He then leaned in and whispered in her ear, "You look really hot in that dress." This made Mikoto very flustered

Leaving Mikoto in that state, he let go of her shoulders, turned to the other girl, and noted, "To be fair, I'd probably have a lot harder time distinguishing between you and the other Sisters."

"That's to be expected, concedes Misaka, secretly hoping that this will change soon. By the way, are you going to try on any clothes, questions Misaka."

Touma shrugged and replied, "I wasn't planning to. I don't really need any more clothes."

Mikoto rolled her eyes at his attitude and said, "Come on, you don't even need to wear your uniform all the time, but you still always wear the same clothes! You should take this chance to change it up a bit."

The boy sighed and conceded, "All right, I guess I'll try on a few things." He went back into the store area and picked out two shirts and a pair of pants. He went into the dressing room to change, and the Misaka sisters also went in to change back into their original clothes, before waiting for him outside.

A few minutes later, Touma reemerged, wearing an orange Hawaiian shirt and a pair of black pants. Mikoto nodded with a smile, "That looks good, Touma!"

"Yes, Misaka agrees with Big Sister's assessment, though she isn't completely sure if the Hawaiian shirt suits you."

Touma looked down at the shirt and said, "Yeah, this is more Tsuchimikado's style anyway." He decided not to get that shirt, and went back to try the other shirt. Once he returned again, he was wearing an orange polo shirt. It was a bit fancier than the shirts he usually wore, but he figured he might as well give it a try.

"You look quite handsome, compliments Misaka, noticing that this departs from your usual fashion sense."

Mikoto nodded, "Yeah, you definitely look pretty sharp." She approached closer to him and carefully adjusted his collar. Her proximity and her smile caused Touma to blush a bit, but he did enjoy her attention. Once she was done, she stepped back and placed her hands on her hips, saying, "There!"

Touma decided to buy this shirt, as well as the pants he was still wearing from earlier. After he changed back into his original clothes, the three of them exited the dressing room area so they could make their purchases.

The boy turned to Misaka 13650 and said, "You really like wearing dresses a lot, huh?" He'd noticed that she had only tried on dresses, while Mikoto had tried on a dress, a skirt, a pair of shorts, and some shirts.

"Yes, Misaka has a somewhat more feminine taste in clothing compared to Big Sister, agrees Misaka."

Mikoto felt the need to retort, "Hey, I wear feminine clothes too!" But she then sighed and gave her sister a smile, continuing, "But it's good that you're wearing what you like!"

"Thank you, says Misaka, glad that Big Sister recognizes her individuality."

As they passed the jewelry section of the store, Misaka 13650 suddenly stopped. "Can you buy Misaka a necklace, requests Misaka while cutely pulling on the boy's sleeve."

Touma smiled at her and replied, "Sure, which one do you want?" He'd been expecting this request, since he'd bought necklaces for all the Sisters he knew in person.

"Misaka would like both of you to choose a necklace for her, shyly states Misaka."

Touma brought his hand up to his face and mused, "Hmm, maybe something to do with Hawaii? 10777-chan chose a bear necklace, since she was in Russia."

Mikoto then pointed at one of them, suggesting, "How about this turtle necklace? It looks cute and colorful!"

"Misaka does like this necklace, says Misaka, mesmerized by the cute green turtle."

Touma then exclaimed, "All right, I'll buy this one for you then." They all soon made their purchases and left the store. Once they were outside, Touma placed the necklace around Misaka 13650's neck, saying, "There you go!"

"Thank you, says Misaka, while holding the turtle in her arms to inspect it more closely."

It was now almost noon, so Mikoto asked her sister, "Hey 13650-chan, do you want to join us for lunch?"

"Misaka would love to, but unfortunately, she has to return to her institution. Plus, she doesn't want to interrupt your romantic vacation together. She is glad she got the chance to meet both of you here, adds Misaka, not wanting to appear rude."

Mikoto pulled her into a hug and said, "All right, I guess I'll see you later then. Bye, 13650-chan!"

"Bye, Big Sister, says Misaka as she returns your hug, hoping to see you again someday."

After the two sisters separated, Touma hugged her as well and said, "Take care, 13650-chan!"

"Misaka should be the one saying that to you, retorts Misaka as she embraces you, recalling how often you get into trouble."

Touma chuckled, "Yeah, you have a point there." After they pulled apart, Misaka 13650 picked up her shopping bag and walked away, beginning to head back home.

Mikoto and Touma then decided to get lunch at the nearby food court, and they both looked forward to heading to the beach later that afternoon.

After returning to their hotel room to drop off their purchases, Mikoto and Touma had gotten ready to go to the beach. Mikoto had changed so that she was wearing her swimsuit under her clothes, and Touma had replaced his shorts with his blue swimsuit. After walking for a bit, the two of them were now at a nearby beach.

Touma spread out the large towel he was carrying onto the sand, and both of them proceeded to sit down on it. The boy let out a relaxed sigh and said, "We're finally here!"

As he quickly took off his shirt, Mikoto's eyes were drawn to his bare and well-toned chest. She wondered what it would feel like to run her hands across it, but was snapped out of her fantasizing when she heard her boyfriend chuckling. She looked up and blushed as she realized that he'd noticed her staring. She looked away and stammered, "S-sorry."

Touma smiled at her and reassured her, "No, it's fine, it's actually really flattering!" He was usually the one that complimented her appearance, so he was glad to see that Mikoto was so attracted to him.

It was now Mikoto's turn, so she pulled her shirt off over her head, and then unzipped and pulled down her shorts. Touma stared at her the entire time, and his jaw dropped when he saw her two-piece swimsuit, which was purple-striped and rather frilly.

Mikoto's face reddened even more, but she soon smirked and used her hand to gently close his jaw, teasingly asking, "Was that really such an amazing sight?"

Touma blushed as well, and replied, "Are you kidding? Watching you take off your clothes like that is really erotic!" Mikoto rolled her eyes but still smiled in response, and he continued, "I didn't expect you to wear such a frilly swimsuit!"

The girl replied, "Well, I thought it was pretty cute! In the past, I probably would have been too embarrassed to wear this, but I figured it's better to just wear what I actually like."

The boy nodded and said, "I see, well, you look amazing in it, Biri-Biri!"

Mikoto grinned and exclaimed, "Thanks, Touma!" She then pulled out two hair ties and tied her hair into pigtails.

Touma raised his hand and gently grabbed and started playing with one of her pigtails, noting, "These pigtails look really cute on you!" This was the first time he'd seen her wear a different hairstyle, and he really liked it.

The girl chuckled and replied, "Well, hopefully they'll help keep the sand out of my hair." Once her boyfriend was done playing with her hair, she pulled out a bottle of sunscreen. Even though it was November, the sun was still beating down on them, so protection was necessary.

After pouring some into her hand, she rubbed it onto her exposed skin, all while her boyfriend watched. He gulped as she applied the cream to her long legs, wishing he could be the one doing that himself.

Mikoto then handed him the bottle and asked, "Hey, could you get my back?"

Touma nodded, "Sure!" He poured a bit of sunscreen onto his hand and started gently massaging it into his girlfriend's back, enjoying the feeling of her smooth skin. While he did so, he casually asked her, "So, are you not immune to damage from UV rays like you are to electric shocks?"

Mikoto closed her eyes and enjoyed the feeling of her boyfriend's firm hands on her bare skin. She replied, "Unfortunately, no. I might be if I could produce UV rays myself, but I can only create radio waves, microwaves, and lower-energy infrared waves."

The boy then mused, "So you can't make visible light, ultraviolet rays, x-rays, or gamma rays? You're pretty strong already, but you'd be even more powerful if you could use the entire EM spectrum."

By this point, he was also finished rubbing sunscreen into her back. As he started applying it to his own body, Mikoto replied, "That's true, the waves I can make are already very useful, but the higher-energy ones are a lot more destructive. I'm not sure how much I'd want to use them in combat, since I'd basically be giving my opponents cancer. I used infrared waves to save the Cold Sleep victim, so I guess I could also use higher-energy waves for medical applications, like radiation therapy." She had once used her ability to create infrared waves to save an attempted murder victim who had been severely wounded and frozen in ice. Mikoto had needed to be very precise in how much radiation she applied to different parts of the girl's body, so that she wouldn't die from blood loss immediately after the ice melted. Fortunately, she had been able to save that girl in the end.

Touma handed the sunscreen bottle back to her and said, "Could you do my back now?" As she started to do so, he asked, "If you're considering medical applications, are you thinking of becoming a doctor?"

As Mikoto was enjoying massaging the sunscreen into his back, she smiled and replied, "Maybe, it would be nice to use my powers more to help people than to fight. Maybe I could even help people with muscular dystrophy, so I could at least fulfill the original reason I gave up my DNA map."

The boy was impressed by her determination, and replied, "Well, you're definitely smart enough to do it. Oh, and if you could create and manipulate visible light, could you do things like make yourself invisible?"

Mikoto finished with his back and sat back down next to him, answering, "Yeah, I could do that by producing light that blends me into the background. Plus, there are a lot of other applications of visible light, which are used by light-based espers."

Touma nodded, "Yeah, you already have a lot of types of abilities, so if you could also use visible light, that would just make you even more versatile!" Noticing a food stand nearby, he then asked her, "Hey Mikoto, do you want to get some ice cream?"

The girl replied, "Yeah, that sounds great!" The two of them headed to the stand and bought some popsicles, with Touma getting an orange one and Mikoto getting a strawberry one. They immediately started enjoying the treats as they headed back to their spot on the beach.

Once they were sitting back down, Mikoto pulled her popsicle out of her mouth and stuck out her tongue, exclaiming, "Look, my tongue is red!"

Touma did the same, and noted, "Wow, my tongue's all orange." He then came up with a fun idea, so he held out his popsicle to her and asked, "You want to try mine?"

The girl's cheeks reddened, but she accepted his offer, and grabbed onto the orange popsicle with her mouth. She then reciprocated, putting her strawberry popsicle in Touma's mouth. Both of them sucked on each other's popsicles and blushed at the indirect kiss. After a bit, they switched again, back to their original popsicles, and then finished them off completely.

Mikoto then suddenly grabbed onto Touma's shoulders and started fervently making out with him. As their cold tongues wrestled with each other, they enjoyed the kiss and the lingering taste of both popsicles.

Once they finally separated, Touma smirked at her and said, "Wow, you're getting bolder and bolder, Biri-Biri!"

Mikoto was a little embarrassed, but she smirked back and retorted, "That's right, so you better watch out, Touma!"

Touma chuckled, "Okay, I will." He then stood up and held out his hand, asking, "Want to go in the water?"

The girl grabbed his hand and exclaimed, "Sure, lets go!" They ran barefoot across the sand until they reached the ocean. Once they were standing in deep enough water, Mikoto let go of his hand and suddenly started splashing him.

Touma tried shielding himself with his arms, but he still got wet. He looked up and saw his girlfriend grinning at him, and exclaimed, "Hey, no fair!" He decided to return the favor, splashing back at her. She was a bit taken aback as she got wet too, but both of them soon started flinging water at each other and laughing.

After Mikoto hit him with a particularly big splash, Touma decided to change the game. He started running after her, vowing, "I'm going to catch you!"

Mikoto turned and began running away from him, and taunted, "Go on, come and get me if you can!" She was pretty fast, so she was confident she could prevent him from catching up for a while.

Touma was also a pretty fast runner, so he was able to keep up with her and slowly gain on her. Unfortunately, before he could catch Mikoto, he tripped on a rock in the sand and fell face-first into the water.

When Mikoto heard him fall, she immediately turned and started slowly approaching him, worriedly asking, "Are you okay?"

The boy stood up and coughed a few times, before lamenting, "Just my rotten luck!" However, since his girlfriend had gotten close in order to check on him, he was able to suddenly reach out and pull her into a hug, exclaiming, "Got you!"

Mikoto pouted and complained, "Oh come on, that's not fair!" Nevertheless, she didn't mind being caught by him. Her hands were now against his chest, so she took the opportunity to run her fingers all over it and feel his toned muscles.

Touma was also distracted by having her wet body pressed up right against him. With her thighs touching his, he had to try really hard to keep his cool. Nevertheless, he couldn't resist for long, and started kissing Mikoto.

After a few seconds, they pulled apart from their kiss. Mikoto then decided to start swimming, and Touma soon joined her. It was a lot of fun, getting some exercise and feeling the cool water on their skin, and they spent quite a while doing that.

Once Mikoto and Touma were done swimming, they started lazily floating in the water next to each other while holding hands. Touma led out a contented sigh and said, "This is so relaxing!"

Mikoto agreed, "I know, right? We definitely needed a vacation." With all the incidents both of them had been involved in lately, it was really nice to get a break.

After a while of just relaxing in the ocean, they headed back onto land. They sat down on the wet sand, not far from their beach towel. Touma started building a sand castle, using his hands to sculpt the sand. He then saw his girlfriend doing the same thing, only she was making something somewhat different.

Touma concentrated on building his sand castle, and he was eventually able to build a medium-sized structure. He looked up and saw that Mikoto had made two large spheres, one on top of the other. He asked her, "Are you making a sand snowman?"

Mikoto shook her head, "No, not quite." She quickly made two small balls of sand and added them on top of the head. She then used her ability to pull up some black iron sand out of the ground and coat the two small balls with it, making them look like eyes. She also drew an arc with the iron sand on the head to make a mouth. She then excitedly announced, "It's Gekota!"

The boy chuckled, "Of course, I should've guessed it from the start!" He then pulled out his phone and suggested, "Want to take a picture?"

The girl nodded, "Sure!" They stood next to each other between their two creations. They both wrapped one arm around each other's back, and Touma took a few selfie pictures. As they examined them, Mikoto noted, "These look great!"

Touma replied, "Yeah, they do. It's neat how you can use iron sand to make the eyes and mouth!"

Mikoto grinned at him and said, "Oh, that's not all I can do with iron sand. Watch this!" She used her hands to build up two small clumps of sand. Pulling up another bunch of iron sand, she used their vibrations to carefully chisel away at the sand, eventually revealing very intricate sculptures of herself and Touma. She then exclaimed, "Ta-da!"

The boy's eyes widened in amazement, "Wow, that's so cool! They're so detailed, you even have your hair clips, and we both have our rings!" He took a few pictures of the sculptures, wanting to preserve his girlfriend's exquisite artwork.

Mikoto continued with her sand sculpting, making smaller versions of her friends, Kuroko, Saten, and Uiharu. She also made sculptures of six of her sisters, Misakas 10032, 10039, 13577, 19090, 10777, and 13650. They all had their unique necklaces, the first four had their iconic goggles, and the last two had their unique clothing. Touma continued to be amazed by her skill and even more pictures.

By this point, it was getting pretty late, and the sun was starting to set. It was a nice, romantic scene, so Touma took another selfie of them in front of the sunset. Afterwards, Mikoto stretched out her arms and said, "Man, I'm getting a little hungry. Let's go get dinner?"

Touma nodded, "Yeah, I'm getting pretty hungry too." They put their clothes back on, packed up all their stuff, and began walking back towards town to find a restaurant, holding hands the entire way. It had been quite a nice day for both of them, and they hoped for more such days in the future.
