It was early morning of April 16, the last day Yuna was going to stay in Hage Village. Yesterday, she told Asta she was going to head home the next day. Saddened by this, he made her promise him two things: that she'd spend the whole day with him tomorrow and that she'd come back in time for the Magic Knights Entrance Exam which was in four and a half months. The two of them got ready for the day as usual. Yuna wore a tan skirt and a thin white low v-neck top with a string bow tied at the bottom of the neckline. She tied some ribbons in her hair on each side of her head. Asta wore his normal outfit and headband. After they were dressed, Asta went around the church and grabbed some food, water, a blanket, and two towels. Yuna looked at him curiously as he packed up everything into a large picnic basket.
"Why are you packing up so much stuff? Aren't we just going to train like we normally do?" Yuna asked as Asta closed the lid of the basket.
"Not this time. I wanna spend my last day with you doing something fun instead of training. Oh by the way, you're going to wanna bring a second set of clothes and undergarments with you." Asta said with a bright smile.
"What are we going to do?" Yuna asked as the two of them went to go pack up a change of clothes before heading out the door with Asta leading the way.
"You'll find out when we get there." Asta said as he grabbed Yuna's hand and practically ran off with her. They walked for about an hour until they came across a small lake. The lake was clear and calm, the surface of the water shimmering in the morning sunlight.
"Oh Asta, it's beautiful!" Yuna said as she inhaled deeply, taking in the fresh clean air.
"I know right! I thought you'd like this place." Asta said as he took off his dark blue jacket and belt with the grimoire pouch. He walked towards the lake and stepped into the water. He waded deeper into the water until it was up to his mid torso.
"Aren't you gonna join me Yuna? The water's great." Asta called from the lake. Yuna walked up to the shore and dipped her toes in the water.
"What about my clothes?" Yuna said as Asta swam around in the water.
"That's why I told you to bring an extra set of clothes. I mean if you don't want to get your clothes wet, you could strip instead. I won't look, I promise." Asta said innocently as Yuna's face grew red just thinking about skinny dipping, and with a guy none the less.
"You know what? Fuck it!" Yuna said as she plunged herself into the cool refreshing lake with her clothes on. She resurfaced and swam over to Asta.
"See? That wasn't so bad, now was it." Asta said as Yuna pouted.
"Well I wasn't gonna strip down while you remained clothed." Yuna said, splashing water in Asta's face.
"Hey, if it makes you feel better, I'd strip too to make it even if you decided to go that route." Asta said innocently as he chuckled. Yuna's face became red from the thought. She sent a wave of water at Asta.
"Hey, what was that for?" Asta said, wiping his eyes clear of water.
"You pervert!" Yuna said as Asta looked at her with a confused look on his face.
"What? I don't see a problem with it." Asta said as Yuna sighed and slapped her forehead.
"Really Asta? A girl and a guy... naked together?" Yuna said as Asta tilted his head to the side, looking at her seeming a bit confused.
"I mean Father said when two people like each other, they sometimes get naked together. I like you, so I don't see a problem with it." Asta said, recalling the birds and the bees conversation Father and Sister Lily had with him, Yuna and Yuno.
"That's for se- nevermind. Let's just swim around. I'll race you to that tree over there." Yuna said as she pointed to a tree at the edge of the lake whose roots dipped into the water.
"Alright! Let's go!" Asta said as he and Yuna got into position, lining up at an imaginary start line.
"Ready? Set, go!" Yuna shouted as she and Asta began swimming as fast as they could towards the tree roots at the bank of the lake. They were neck and neck, but Yuna ended up reaching the tree slightly before Asta.
"Damn, you beat me. You're a fast swimmer Yuna." Asta said, impressed by the results of their swimming race.
"I barely won Asta. And it's probably only because you have more muscle than I do and therefore weigh more which can slow you down, especially in the water." Yuna explained as Asta looked at her seeming impressed.
"Wow Yuna, you're really smart." Asta complimented Yuna. Honestly, she thought that was common knowledge. But Asta wasn't exactly the brightest. He reminded her a little of her best friend Natsu Dragneel. Yuna chuckled while thinking of their similarities. Asta looked at her confused.
"Why are you laughing?" Asta asked Yuna.
"I was just thinking, you remind me a little of my best friend Natsu Dragneel." Yuna said as Asta looked at her even more confused.
"Natsu Dragneel? But I thought Izuku Midoriya was your best friend." Asta said.
"Izuku is my best friend from home. Natsu is my best friend in Earthland. You can have more than one best friend, you know." Yuna clarified.
"Oh. Then am I your best friend too?" Asta asked as Yuna approached him and hugged him, making him blush.
"Of course you are, Asta! You're closer to me than anyone else in this world." Yuna said, squeezing him tighter before letting go of him. Suddenly, Yuna's stomach growled and Asta chuckled.
"Looks like you're pretty hungry. Let's go back and eat something, shall we?" Asta said as Yuna nodded her head in agreement. They waded back to shore. As they got out of the water, Asta noticed Yuna's white shirt was now see-through and her teal bra was showing. Asta's face got red as he started to get an erection. He quickly covered his crotch which caught Yuna's attention. She looked at him curiously.
"Uh, I have to use the bathroom. Excuse me a minute." Asta said as he quickly ran off into the woods nearby. He hid behind a large tree.
"Phew! That was a close one. Why am I getting hard from seeing through Yuna's shirt? Am I really attracted to her in that way? That can't be, I love Sister Lily after all. But then why is my body reacting to Yuna like this? It never does this for Sister Lily. Regardless, I need to take care of this before I go back." Asta said to himself as he lowered his pants and boxers and began stroking his member, letting out small moans as he did. He couldn't stop thinking about seeing Yuna's bra through her shirt. Then his mind wandered more, imagining Yuna without her bra on. The more Asta's mind wandered, the faster his hand moved. His penis started to twitch as he neared his orgasm.
"Ah~ Yuna~ I'm... I'm cumming!" Asta moaned as he bucked his hips and released his semen all over the tree trunk. After he came, he pulled up his pants and boxers and headed back to where Yuna and their stuff was. By the time he got back, Yuna was already changed and had spread out the blanket under the picnic basket.
"Better?" Yuna asked as Asta nodded. He joined her on the blanket and together they rummaged through the picnic basket and got out some bread, pot potatoes, and canteens of water. They had friendly conversations while they ate. They talked for hours even after they finished eating.
"So what are your other best friends like?" Asta asked Yuna about Izuku Midoriya and Natsu Dragneel.
"Well I haven't seen Izuku since he was three and I was four. He's probably changed a lot since then. But when I knew him, he was a huge fan of heroes. Back where I'm from, roughly eighty percent of the world's population are born with quirks, or superhuman powers. Heroes are people who are certified to use their quirks to rescue people or deal with dangerous criminals. Izuku didn't have a quirk yet when I knew him. But it was still his dream to become a hero one day. He most likely has his quirk now though. Actually, my quirk is what got me to Earthland in the first place. That's where I met Natsu. Now Natsu, he's carefree and reckless in nature, but he's a very loyal friend. He's a fire dragon slayer, which means he possesses fire magic that could potentially take down a dragon. He learned it from his foster father Igneel who was a fire dragon, the Fire Dragon King in fact. I learned dimensional dragon slaying magic from a dragon as well: Planeus, the Great Dimensional Dragon." Yuna said as Asta looked at her seeming confused.
"Wait, did you say you and Natsu learned magic?" Asta said, not quite believing what he was hearing.
"Yeah, in Earthland no one is born with magic. You learn it." Yuna stated as Asta's interest suddenly piqued.
"So if you took me to Earthland, do you think I could learn magic too?" Asta asked, his eyes glittered with anticipation.
"I'm pretty sure you could learn to use magic there, yes." Yuna said as Asta got really excited.
"You've got to take me there someday Yuna!" Asta practically yelled like a little kid asking their parents to take them to Disney World.
"Alright, I will. But just so you know, you still won't be able to use magic here. I can't use my dimensional dragon slayer magic in this world." Yuna said as she chuckled.
"I don't care, I just want to be able to use magic at least once in my life. But that would be a nice bonus if I could use magic here too." Asta said as he imagined what it would be like to use magic.
~Time Skip~
It was getting close to sunset and Yuna and Asta were back at the church. Their foster family gathered outside the church to say goodbye to Yuna before she tried to go home again. She flipped through her grimoire to find the spell more powerful than her typical teleportation spell Fallen Angel Gate. Eventually she came across a spell that would reach way beyond her normal range which was already pretty far considering she had a four leaf clover grimoire. It had appeared in her grimoire during the fight against the Diamond Kingdom mages that invaded Fanzell's home. The spell was called the Door of Fate and it required at least one other mage to lend their magic power in order for the spatial magic user to even cast it. This was probably it.
"I have a favor to ask of you guys. I need you to stand in a circle around me and lend me any magic power you have at the moment so I can cast this spell to get home." Yuna asked her foster family for help.
"Of course Yuna. We'll help you get home." Sister Lily said as she held her hands out in front of her. Everyone did the same except Asta since he didn't have any magic power. They started to transfer their magic power to Yuna. She could feel the level of magic surging within her rising.
"Okay here it goes. Compound Gargantuan Magic: Door of Fate!" Yuna said loudly as a giant circle of magic runes formed around Yuna where everyone was standing. Suddenly, a large portal formed in front of Yuna. It looked different from her normal portals which were smaller and swirled with hues of blue. This portal was a bit bigger and had golden runes lining the edge of it. This was it. Before Yuna stepped through the portal, she turned to Asta and ran to him. She tackled him with a hug.
"Thank you for everything." Yuna said as Asta returned her embrace.
"I'm gonna miss you Yuna. Make sure you come back in four months so we can head to the Magic Knights Entrance Exam together like you promised, okay?" Asta said, trying not to cry but epically failing.
"I will, don't worry. I'm going to miss you too Asta." Yuna said as she kissed Asta on the cheek which made him blush. She let go of him and went back to the portal. She looked back one more time at Asta and her foster family and waved goodbye.
"Bye everyone! I'll see you again in four months!" Yuna said as she turned around and stepped through the portal.
