The Demon Lord reincarnated and became the... Caretaker of a kindergarten?

Chapter 8

(A/N Notes: I wrote this chapter while running solely on my adrenaline to keep myself awake to finish it late into the night, so if everything sounds weird, it's all my fault! Nor am I going to change it, since that would be too much work... ... ... Well, probably I will rework this story some time in the far future)

It had been just 30 minutes since Katsuo began cleaning Misaki's house, and he was almost halfway done, granted he was cheating by using magic to help him clean the house

But un-sportsmanship aside, the results were very clear. The living room that until now looked darker, damper, and more dangerous than a demon king castle was now sparkling clean, its walls were restored to their previous pristine white color and the even air felt... purifying. The kitchen whose sink and stove looked like a poisonous swamp and a poisonous field of mushrooms respectively, were now shining with their once-lost metallic sparkle as their water and fire felt they were blessed by a holy entity

And if Katsuo had only cleaned half of the house, that meant that there was still the other half...

"..."

Katsuo stared at the remaining evil/dirt area of the house... The corridor that led to the storage room, Misaki's bedroom, and to the bathroom

"... *Looks at the hours* ... Welp, I should be able to finish this before dinnertime"

Then Katsuo began spinning the mop in his hand as if he was in an anime and the mop was a spear and put it inside a bucket that was right beside him. And then he... Walked away and began picking up the bigger trash that was occupying the most space, steadily he made the corridor less and less crowded with boxes and magazines, once all the big trash was taken out and thrown in the trash bag or put together for recycling. Katsuo picked up his weapon, the mop, back again, and began mopping the corridor's floor

With one sweep, the dusty and dirt floor started sparkling clean, without a single speck of dust left in the way, and that was also true for the walls and even the ceiling as he swept a cloth to remove the stains of dirt from those places. Eventually, he arrived at the bathroom, and when he opened the door, he was greeted by the surprising sight... That it was pretty clean

"... So you know how to clean a house, Misaki-chan... Oh well"

Although it was clean, Katsuo saw that there was still room to leave it even cleaner, so he did a quick cleaning of the bathroom, after that he stood in front of the door to Misaki's bedroom. And of course, that was a bedroom of a girl, an adult woman at that, so of course, Katsuo didn't have any other option other than... Entering it without a second thought. Inside he noticed that it wasn't as dirty as the rest of the house, but the air inside still felt kind of stale as it also gave out a weird bite similar to a demon lord's castle...

"Purifying air filtration!"

But it was not like Katsuo cared about either of those things as he used magic to make the air of the room feel more refreshing as he cleaned the floor and walls of the room to make it look brighter. After that, he decided to finish cleaning the storage room before he went on with the other things that also necessitated some cleaning

Then when he opened the door to the storage room, he was greeted by the sight of a bunch of boxes crudely piled up inside the small room, and with the door open they were now on the verge of collapsing right on top of him, and then they collapsed threatening to bury Katsuo under dozens of dirt and dusty cardboard boxes...

But then Katsuo began moving so fast that everything appeared to go in slow motion, then he began picking each falling box one by one and folding them neatly organizing them for recycling, he did that until all boxes were folded. Then with no more obstacles in the way, he quickly cleaned up the storage room, and now he could focus on the other necessity he needed to do in Misaki's house... Washing her clothes

So with that, Katsuo decided to take any of her remaining clothes from her wardrobe, and he quickly cleaned the wardrobe, which had a faint smell of mold in it, with all of Misaki's clothes gathered in one place, instead of scattered around the house, which also meant that many of her underwear pieces were in plain view

"Hmmm... This is bad, some of these clothes have mold in them that normal water and soap won't be enough... Welp..."

Katsuo then got up and put his hand on the washing machine

"First of all to remove all kinds of dirt from your clothes, first you enchant your washing machine so that it'll start producing holy water, then you pick a bottle of soap for clothes and enchant it to provide more holy damage and kill all impurities, and finally you pick a clothes softener and enchant it the same way as well, now all of your clothes will feel like as if you're touching the clouds... Man, I like saying stuff as if I'm in a commercial"

And with that Katsuo began washing every single piece of cloth in Misaki's house

Some time later

"Haa... I'm tired... Taking care of not only paperwork but also spoiled kids until late in the afternoon is really exhausting... Haa... I want to take a warm bath and forget about everything that happened today"

Misaki was returning home from the kindergarten with a very tired face, and because of that, she was returning directly to her house. Then when she finally opened the door she was greeted by a strange sight

"Eh?..."

She looked to her right, the kitchen was clean, she looked to her left, the living room was sparkling clean, and in there... Was Katsuo ironing one of her panties, and it was one of the bolder panties as well

"Welcome home, Misaki-chan! Do you perhaps want dinner, a bath, me, or perhaps all of them?"

"Yes, I would like all of them... NOT! What do you think you're doing?!"

"Cleaning your house and ironing your clothes which some were smelling of mold"

"That's not it! I mean what you're ironing right now!"

"This? It's one of your panties, I must say it's quite the sexy design, though in my opinion, the cute ones fit you way better"

"I don't want your bloody opinion! You either stop that right now or I'll stop you by force!"

"I wouldn't recommend you to do that"

"Huh? Why?"

"Because you're definitely going to step in one of your clothes on the floor, slip and we'll end up kissing on the lips. Not that I mind getting kissed by you though"

"Alright, I'm going to kill you now"

Misaki whose mind was tired and filled with anger, stepped forward as she went directly towards Katsuo, but exactly as he had predicted. Misaki accidentally stepped in one of her clothes, making her foot slip, which caused her to lose balance and start falling forward

Katsuo who already knew that was going to happen, had already stopped ironing her panties and prepared to receive the falling Misaki. And when she fell right into his arms, their lips overlapped

"Hey, onii-san. Are you fini-"

And just as Misaki was accidentally kissing Katsuo, Kanon walked in from the front door and saw Misaki on top of her brother kissing him

"..." *Sweating heavily* "S-sorry to bother, I-I'll come back after you two are finished"

And she decided to make a tactical retreat since she didn't want to know what could happen to her for interrupting that moment

"WAIT! YOU GOT IT WROOOOOOONG!!!"

Misaki tried to go after Kanon, but it was too late already
