I don't own anything from Danball Senki WARs

Summary: Yuno prepares desserts but is unaware that Arata cannot consume one of the ingredients. Arata is toutured by his allergy reaction and lactose intolerance.

Yuno was humming as she mixed some batter in the kitchen one fine Saturday afternoon while most of the students were either lazing in their dorms or enjoying the sun outside.

"Yuno, what are you making?" Catherin asked when she entered the kitchen, looking for her friend.

"I'm making some desserts for everyone." Yuno beamed. "But I can't tell you what it is yet."

Catherin pouted. "Can't you tell me?" She pleaded. "I won't tell anyone."

"Alright," Yuno rolled her eyes and leaned in to whisper in Catherin's ear. "It is…"

Catherin grinned when she heard the name of the dessert. "Wow, it's been a long time since you made them. I'll look forward to it. And don't worry, your secrets safe with me." She pretended to zip her mouth and throw away the key.

"Good, otherwise," Yuno smirked. "I don't think there will be enough for you."

Catherin shook her head a bit and watched her for a moment. "Are you making these for someone? You practically stopped baking since last semester."

Yuno blushed a bit but it was not noticeable to the other girl. "No, I just wanted to let Arata, Mia and Reika try it."

"Whatever you say." Catherin grinned devilishly. "But I bet you want Arata's option of it."

"W-what!?" Yuno stuttered.

Catherin rolled her eyes. "Oh come on, I can see that you like him. I'm not blind you know. But I think you could do better with someone else. He's completely dense and probably does not seem to be the type of person to get a girlfriend."

Yuno narrowed her eyes. Catherin was wrong. Arata is not dense to her feelings and she could tell, with the help of Mia, that he liked her more than a friend, he was just afraid to show it in case she misinterpreted it as he only liked her because she looks like Maddie.

Meanwhile, Arata, Reika, and Mia were in the Aviane Room practicing their powers after a long time of not using them properly. Each of them was wearing training suits based on the color of their elements.

"Take that!" Reika sent a torrent of water straight at Arata who jumped out of the way to avoid it. With his side open, Mia shot an icy wind at him. But Arata instantly ignited his hands and sent a stream of fire to counter it.

"Good, but not good enough." He smirked. His Fire Staff materialized in his hand. "Come on."

Reika gritted her teeth and nodded at Mia. They ran forward and double teamed against him but every one of their attacks were blocked by his staff. Once he saw his chance, he ignited his staff and started attacking the two girls. Mia felt the brunt of the attacks because her weakness was fire attacks and received several burns on her skin.

Reika was fed up and shaped a water sphere in her hands and tossed it up in the air. Immediately, it busted and water rained down on the trio. Arata's attacks instantly became weaker significantly and Mia froze the water on her burns to heal them.

"You got me." Arata sighed but smirked. "But you should not let down your guard because of that!"

He tossed his staff at Mia who jumped and landed beside Reika, unaware that she fell into his trap. Once the girls were in the same place, Arata shot two fireballs at them, sending them flying.

"Ow!" Reika cried when she landed. Luckily she did not receive a lot of damage since her element is water but Mia had some nasty burns on her chest.

"Arata, you know that I can't stand fire, so can you tone down your attacks a little?" Mia groaned and pushed herself up.

Reika went over to her and healed her burns with her healing water technique. "There, it should sting a little but it'll heal by tomorrow."

"Thanks." Mia shot a glare at Arata who had a slight apologetic yet smug smile on his face. "And wipe that smile off your face!"

"Sorry, but it looks like you're out of practice with your powers."

"Alright, that's enough." Yuko said as she jumped down from the platform she was watching from. "All of you did well today. Arata, your speed needs to be improved; Reika, you need to heighten your accuracy of your attacks; and Mia, try to increase the strength of your powers."

"Hai!"

"Then, all of you better get cleaned up before you head back for dinner." Yuko dismissed them.

Inside the locker rooms, Mia picked up her CCM and noticed that she had a message from her brother. After reading it, she groaned. "Reika, I don't think I'll be heading back for dinner with you guys. Muraku wants to meet me at the Swallow Café for dinner. He wants to talk about something related to our mom's birthday present."

"Sure." Reika shrugged. "But you'll miss out of Yuno's dessert. She was looking forward to treating us to it."

"How did you know that she's making desserts?" Mia asked curiously.

"Um, Catherin told me." She answered sheepishly.

"I envy you." Mia muttered softly. "Up till now, most of the class still treats me like trash, Catherin being the ringleader."

"Hey, just give them time." Reika wrapped her arm around her friend comfortingly. "They don't know you that well so they cannot help but see Muraku in you."

Mia shrugged and grabbed her bag. "Can you save some of Yuno's desserts for me?"

"Sure thing."

Later after dinner, Yuno brought out her desserts. "Here we are, chocolate cookie balls."

"Wow." Reika admired the round balls and took one. "Does it have any filling?"

"Yup." Yuno smiled as Reika and Arata each took a bite of their chocolate cookie balls. "It's vanilla cream."

Almost instantly, Reika chocked on hers while Arata quickly grabbed some tissues and started sneezing into them.

Everyone's eyes became wide at their reactions. "What's wrong?"

"Oh dear." Reia muttered. "I think no one told you this, but Arata is allergic to cream and is lactose intolerant."

Yuno's hands flew to her mouth. "I'm so sorry!"

Arata opened his mouth to reply but quickly turned away and went into a sneezing fit. "It's- Achoo- fi- Achoo- ne! Achoo! Achoo!"

"Arata's allergy symptom is uncontrollable sneezing." Reika said, shaking her head. "Did you swallow any of it?"

In the mist of his sneezing fit, Arata managed to nod. Reika groaned and turned to Hikaru who was not too far. "Hikaru, do you mind if I look for Arata's medicine in your room?"

Hikaru shook his head and got up from his seat. "I'll come with you."

Reika nodded and they went off to the dorms. Meanwhile, Arata's sneezing had subsidized long enough for him to call out. "The medicine is in my drawer!"

"Ok!"

Suddenly, Arata clutched his stomach. "I don't feel- Achoo- good. I'm going to- Achoo- lie down in- Achoo- the common room- Achoo- for- Achoo- a while."

"Will you be alright?" Yuno asked worriedly.

Arata nodded. "Ye- Achoo, it's just a bit of- Achoo- stomach upset."

"Do your allergy symptoms include stomach upset?" Sakuya wondered.

Arata shook his head. "No, it's my- Achoo- lactose intolerance."

"Oh dear." Yuno muttered and went to his side. "I'll help you there."

"Tha- Achoo-nks."

Arata lied down on the couch with a hand over his stomach which was churning uncomfortably each second. But by now, his sneezing had stopped much to his relief.

"Arata, here." Reika handed him his medicine and a cup of water as Hikaru and Yuno sat on the opposite couch.

"Thanks." He took some pills and gulped them down with the water. "I hate my allergy reactions."

"And your lactose intolerance." Reika added. "Get some rest. I've talked to Tome-san and she said that you can sleep here for the night if you find that you cannot go back to your room."

Arata managed to grin weakly. "Did I ever mention that you are the best sister in the world?"

"Once or twice." Reika rolled her eyes. "I'm going to my room now. Good night." She said and left.

Hikaru soon got up to go back to his room. "You better take care of yourself." He said shortly and left.

Arata's eyes adverted to the only person left in the room. "Aren't you going to go too?"

Yuno shook her head. "It's my fault that you are in this state. So, until you go to sleep peacefully, I'm not leaving this room."

Arata gave her a small smile. "It's not your fault. I didn't tell anyone that I cannot take cream or dairy products."

"But still…"

Arata took her hands and held them firmly. "I told you already, it's not your fault. So stop beating yourself for it."

Yuno blushed at the contact. "Ok…"

"Come on Arata." Reika fumed from where she was watching. "Just kiss her already."

"I don't think he's going to do that."Mia whispered as she appeared beside her, startling her.

"Mia, where did you come from?" Reika hissed.

"I just got back and I heard about everything from Haruki." She whispered back. "Arata never liked it when you spied on him and Maddie on their dates so you should go before he spots you."

Reika scowled and nodded. "Point taken, let's go."

They sneaked away successfully before Arata, who was occupied with Yuno, sensed them.
