"Yep, it's Isekai Sickness, and a pretty bad case of it. I suggest plenty of bedrest, otherwise you're going to be in for a hard recovery period."

"... Greeaaaaat..." Naruto groaned as he laid in bed. "Kurama... fix it..." Naruto complained to Kurama to fix it.

"My chakra doesn't work that way idiot. My chakra can't be used to stop you from getting sick or drunk, though I do increase your regeneration and recovery period for drunkness... illness on the other hand is a biological cell function with invading pathogens-"

"Shut up... you're too loud in my head." Naruto groaned as he rolled over while the doctor left his room. Kurama was speaking in jargon that he didn't care to understand, because Kurama was smart despite the fact that he was also a bit of an idiot at times. "... So you can't fix it... then why haven't I gotten sick in the past?"

"You're an Uzumaki who lived a super active lifestyle and trained a lot, not to mention you spent most of your life isolated from others. You've barely been exposed to sickness that you weren't resistant to. When did you have much of a chance of getting sick before now?" Kurama raised a fair point. Naruto had a very healthy body that led to him not getting sick very often, and when he did get sick, Naruto just kept training himself and kept sweating up a storm until the sickness was gone.

Naruto had been too stupid in his younger years to realize when he got sick, and proceeded to train through the pain.

-Outside-

"Isekai Sickness!?"

"... Technically, it's only called that because people from other worlds just don't have immunities to some of our diseases. Isekai Sickness is just a person getting sick with multiple things that don't exist in their world." Stunk wasn't too worried about Naruto. When a person from another world got 3 or 4 diseases at the same time, it was called Isekai Sickness to explain it.

It was a good way to jump start the immune system.

Ivy, in the kitchen, saw her chance.

News spread fast that "The Legendary Army Fucker" was sick.

-First Visitor-

"... Did the window stop working?" Naruto suddenly felt the sunlight he was basking in stop. Realizing that he had said something stupid, Naruto looked out the window and saw a giant eyeball staring at him.

...

"Heard you were sick." Death Abyss whispered as she crouched down outside of his window, opening it up with magic from the outside. She reached in the window and pat him on the head to try and comfort him. "... Need somebody to wipe your sweat for you, or how about some nice cooking?" Death Abyss asked him with a smile, that was not visible from the window. Naruto just stared at her with a dull expression.

"No thanks, can I just sleep this off?" Naruto didn't think she would be able to help too much.

Not with her size as the fact the room was too small to fit her inside of it.

"Okay, lets talk politics later when you're feeling better. I want to get your opinion on regulations on government-"

"Bye."

-Second Visitor-

"... Dude... you are not helping by being here. Thank you for the flowers though. I can't smell them at all." Naruto stated as he looked at Ainz.

"I closed up the shop early to check on you, since you loaned me the money to start my own flower shop, it is only fair that I take care of you in your time of need." Ainz spoke genuinely with a gentle nod of his skull. "Maybe I can cure you with magic... the Cure spell should do-"

Ainz cast the spell.

Naruto was engulfed in an explosion.

"Isekai Sickness reacts very poorly to magic... just... just go and ask Meidri if she can get me new sheets." Naruto palmed his face. His clothes were ruined, and his bed was burnt up. Ainz was sorry, and left the room quickly to go and do that.

-Third Visitor-

"Sup guy, lets get you some-"

"Leave Stunk, I'm not feeling like busting a nut right now."

"Alright, see you later man. Me and Zel are going on a quest to get some good fucking money, after that, we've got a great place that we want to take you and Brooz too... Brooz saw it on his own quest awhile back and thought you would enjoy it." Stunk took the hint and left the room without a complaint. He thought getting Naruto to work up more of a sweat would be just what he needed to overcome this sickness.

-Fourth/Fifth Visitor-

Meidri stopped by to give Naruto new sheets and bring him a spare set of pajamas.

"Get better soon, okay?"

"Thanks Meidri." Naruto laid back down in a fresh bed with fresh clothes on, smiling to himself. She left the room without causing any trouble for him. Naruto glanced over at Crim, to see him floating there as if unsure of what he wanted to say or do. "... You can stay if you want, I finished translating my favorite book if you want to read it." Naruto stated to Crim with a sigh.

Crim beamed and took the translated book from the table, opening it up to the first page with sparkling eyes. Those eyes changed to concerned eyes though.

"... I should go, and let you sleep."

"Jusy be quiet, and when you leave, give that book to Samhain... his wife has a book store, I want her opinion on it."

"Sure, I'll make sure that Samturn gets it." Crim used the name that everyone called their demon friend. Samhain Samturn, while everyone else was more respectfull, Naruto tended to use first names for most people. Funny enough, Samhain didn't seem to mind in the slightest. "So... quick..." Crim stopped himself from talking when Naruto closed his eyes and turned over onto his side.

Right, sleep.

Crim left after awhile to read in his room.

-Sixth Visitor-

"Say aaaaaah."

"Go away midget..." Naruto rolled over to his other side away from Piltia as she tried to feed him. "I'm not hungry... I just want to sleep." Naruto complained about everyone ruining his sleep. He appreciated the effort his friends were going through for him, but he was fine. He needed bedrest and that was about it.

"You're cranky, you really do need a nap... and you're sweating right through those fresh clothes. Come on, strip down so I can wipe the sweat." Piltia stated as she showed the towel ready foe the job. She had a teasing grin on her face. "... but Isekai Sickness is a serious thing Naruto, you need to eat to keep your strength up. Your body is getting sick with stuff not from your world." Piltia became serious when she explained what was going on.

Naruto pointed the door.

"I don't want to get anyone sick... so please, just leave." Naruto didn't want to get his friends sick, since this stuff was from their world, they could still get sick with it too. "I've gone through suffering way worse than this before, I'll be fine." Naruto told her with a twitching eye.

"I've heard Isekai Sickness feels like somebody is shoving a fist through your chest, you don't need to grin and deal with it alone."

"It feels nothing like that, I've had a fist through my chest before. My head feels more like I got dropped from orbit."

...

"Really?" Piltia asked with some shock at the casual way that Naruto told her that. "... So that comparison isn't apt, but the head thing is more accurate... how many times have you been dropped from orbit?"

"... Three times? Once when I jumped off a tree that stretched to the skies, once when me and my best friend exploded in orbit, and a third time rather recently... I'm very durable..." Naruto stated as he listed the 3 times in his life that he had fallen from low and high orbit and crashed to the ground.

-Much Later-

A good nap was just what he needed to help with his aching head.

He felt somebody looking at him, and when he opened an eye, he noticed that Ivy was just silently reading a book next to his bed. She had some food on a tray sitting by his side, but the food had gone cold.

'She didn't wake me up... at least Ivy knows I want to sleep.'

"Hey Naruto... don't worry, I'll be here when you wake up. You can fall asleep, nobody else is going to bother you."

Naruto sighed in relief and closed his eyes, letting himself go back into the sleep that he needed more than anything right now.

The quiet was nice.
