Six Days

Six days later, Kisuke and Yoruichi finished off the corrupted Spirits simultaneously by shredding their upper bodies, "Alright~! Let's go home~!" Kisuke declared after watching as the Spirits became ashes.

Kuroka fell to her knees, shivering while muttering in delight, "...Finally... I don't ever want to do that again, nya..." However, her eyes were empty and her expression was listless.

Medusa also had the same expression but didn't say anything as she blankly stared at the mountains of ashes and recalled their six-day long battle.

On the first day, since none of them were used to the tentacle's movements, all of them got hit by a force comparable to a speeding 100-ton truck. While Kisuke and Yoruichi only got hit once and immediately recovered, Kuroka and Medusa got hit multiple times, and each time, Kisuke would bring them back like some necromancer from an RPG game.

On the second day, Kuroka and Medusa were still being hit, but a lot fewer times. However, this was also the day when Sona's magic lost its effect and the 59th floor returned to how it was. Due to this, caterpillar monsters and flower monsters were also flooding in.

Kisuke and Yoruichi got hit with acid multiple times, but they immediately got back up and were able to devise some moves to keep the acids away from them, thus, they were able to continue relatively fine.

On Kuroka and Medusa's side, however, they were just getting used to the tentacles and the addition of the monsters made it so much worse for them. Every time when their injuries reached a certain threshold, Kisuke would immediately pull them out of the battle and heal them for about half an hour before sending them out again.

Although they were thankful to him, they just really wanted to rest at that point. They were wondering how the two of them could still move as if it was the first day. There were times when they wanted to receive injuries deliberately to get more rest time, but after seeing the two of them work so hard, 'cheating' for some relief became unbearable to think about.

Gathering up their courage and motivation, Kuroka and Medusa continued battling alongside the two crazy fighters.

On the third day, some changes happened and Kisuke immediately asked everyone to wear a cloak and a mask. Everyone immediately followed his instruction and since Kuroka would be using her Sacred Gear more often from now on, Kisuke also asked her to take it back temporarily.

After preparing themselves, the red-haired tamer Revis appeared on the 59th floor along with new waves of monsters. Since Kisuke and Yoruichi deemed her as a nuisance in their precious training time, both of them teamed up against her while drowning her with pure killing intent.

It only took a few minutes before Revis became gravely injured and scared for her life as she hurriedly escaped to the upper floors, using the monsters she brought as cover.

Kisuke and Yoruichi didn't go after her since she was the Loki Familia's problem and Sona, Aika, and Koneko were already working closely with them. They did promise them that they'll leave her to them.

On the fourth day, Kisuke started letting small scale magic from the corrupted Spirits through to increase the difficulty. Kuroka and Medusa were back to struggling to keep up. But thanks to their earlier experiences, they were able to adjust easier compared to the previous increase in difficulty. Although, they were still not as adaptable as Kisuke and Yoruichi, but this was already a very welcome improvement.

On the fifth day, Kisuke stopped holding their magic back and the group had to think of various ways to survive the onslaught of tactical scale magic. Unlike what they were doing before, which was essentially just working on their own, the group now had to work together so that they could 'survive' without using their real powers.

On the sixth day, the smaller monsters already disappeared entirely while the corrupted Spirits became noticeably withered and tired. They figured that they wouldn't get many benefits from lengthening the training even further since they could already perfectly dodge everything that got thrown at them, so Kisuke and Yoruichi finally finished the unfortunate monsters off.

"...I'm tired, nya! I want to take a bath!" Kuroka shouted as she stood up. She was already spent and most of her Mana and Ki were gone despite doing her best to ration and recover them in the middle of the fight.

But the most drained person among them was Medusa as she couldn't even stand up properly. She had to use the Mana which kept her body intact properly functioning just to keep up with them. It was also on the third day that she had to undo her transformation to save even a bit of Mana.

In her listlessness, she suddenly felt two arms wrapping around her and lifting her off the ground. She hurriedly looked up to the person who 'princess carried' her, "...Master?"

While passing her some of his Mana, Kisuke smiled at her and said, "Thanks for the hard work. You may rest now."

She 'needed' to refuse, but thanks to the gentle Mana coming from him, Medusa succumbed to the comforting feeling and closed her eyes. A few seconds later, she fell asleep in his arms.

"She really tired herself out this time," Yoruichi said as she took a peek at her peacefully sleeping face.

"Although her Mana reserves are a lot lower than mine because of her body, unlike me, she didn't utter a single complaint, nya. She's too serious, nya!" Kuroka added as she brushed Medusa's bangs to the side.

Yoruichi patted Kuroka's head and said, "You also worked hard. Thanks for that."

Kuroka giggled and replied, "I can't really be left behind. Sona-chan, Aika-chan, and Shirone are also catching up fast. I have to work hard as their big sister, nya!"

"Alright, let's go back up. It should be about time that the Loki Familia reaches the surface. We still have to take care of those three who did their best." Kisuke then used the same magic circle which they used to teleport to the 59th floor to return to their underground hideout.

After they arrived home, Kisuke gently laid Medusa on her bed and set some contraptions which could gather and purify Mana so that she could recover easier and more comfortably.

Kisuke, Yoruichi, and Kuroka then went up to the surface and directly to the Candy Shop to wait for the Loki Familia. As they entered the shop, Hestia came running and did a flying tackle to Kisuke's gut.

Kisuke had to soften her landing since she would only get hurt from her reckless move otherwise. Hugging his waist Hestia looked up smiling, "Welcome back~!"

"We're home, Hestia-sama."

But before they could enjoy their reunion after a week of absence, a girl with golden hair came running in and opened the store. Ais immediately saw Kisuke and spoke, "Kisuke... Please come with me to the 18th floor."

But before she could receive his reply, another person, or rather, a God came running in, "Hestia! Hestia, are you in there?" Miach came running in too with rapid breaths, "Please help my child!"

Corner:

28th00: So, the difference between being ancient (Medusa) and a Genius (Kuroka) compared to those two who are both Ancient Genius' who have spent the majority of their… 300-500 years(?) of… unlife(?) fighting eldritch monsters, is very large indeed. It's nice to see that Hestia is literally the "Go-to" for help though! She's Bestia for a reason! Now, what the hell happened to poor Bell this time? Hestia never abandons her friends (Loki is obviously her BFF though) or people that need help!

Alexander: Well, screw the rules. It's a case of "Semper fidelis", so roll in and crash the party.
