After the school trip ended, Kuroka and I started heading to Magari's place on weekends for training.

As for my senjutsu, Magari praised me for having solid fundamentals when it came to manipulating my own ki, but said I was only so-so at sensing other living beings' ki and still had a long way to go with feeling the ki of nature itself.

"Seriously, what kind of twisted training would even produce results like that?"

Since she said that, I figured it was necessary for my education and ended up demonstrating and explaining Ittou Shura in detail. For some reason, I felt like that just made her even more exasperated...

"Well, whatever. I called it twisted, but it's not like you're doing anything fundamentally wrong—though balance is always better than not having it. Keep up that Ittou Shura training of yours. In exchange, I'll focus on teaching you how to sense and manipulate natural ki."

"Yes! Thank you very much!"

….

...I'd love to punch that enthusiastic first-day version of myself in the face. After that, I got beaten by waterfalls (in winter), did polar bear swims, got buried in dirt, hugged rocks, meditated by campfires next to magma, and got thrown out of planes without parachutes for nature sensing training... That woman seriously shows no mercy!

Kuroka was working on improving her barely-learned spatial manipulation techniques while also training in time manipulation.

The spatial stuff seemed manageable as an application of barrier techniques, but time manipulation was apparently several levels harder. I'd often see her holding her head going, "What the hell does 'four-dimensional spacetime is a membrane-like four-dimensional cross-section in five-dimensional spacetime where only gravity can propagate' even mean?!" Yeah, I had no clue either!

The training progressed... smoothly? Let's go with that.

"...So anyway, that's how Magari dropped me from 5,000 meters up today too."

≪Hmm, it sounds like both you and Kuroka are working hard, which is good to hear—though I had no idea Magari-sama was quite so strict...≫

I'm back in my room now, talking to the tube fox Izuna.

Since Izuna's clones share the same consciousness, they can instantly share information with other clones, and we can use that to basically make phone calls.

The Izuna clone I left in Kyoto is usually with Kunou, and we chat about random stuff a few times a week.

≪Well then, Ikki, until next time!≫

Apparently Kunou's taken to calling me Ikki now. She said Yasaka told her being friendly was important in modern times... I'm starting to think that woman might have sadistic tendencies.

"Yeah, see you later. Good night."

I cut the connection with Izuna.

"Finally done?"

Kuroka wrapped her arms around my neck from behind and pressed her gigantic weapon against me!

Her physical contact has definitely increased since the school trip ended.

Something really soft is hitting the back of my head! I think my favorability with Kuroka went up after the tsuchigumo incident, but her provide me with genes stance hasn't changed, so I can't make a move.

Kuroka probably wouldn't mind, but as a guy, I want her to actually like me first—a purely physical relationship with Kuroka... Yeah. Just putting that into words makes it sound dangerously lewd.

...I've been enduring her temptations like this for about a year now.

I'd visit Kunou during events like New Year's, Obon, and Setsubun... or rather, when she tearfully asked things like "Are long-distance relationships doomed to fail?" I didn't really have a choice but to go see her. What the hell are they teaching that kid?! Damn sadist mother!

In the middle of all this, Kuroka suddenly asked me something like she'd just remembered.

"Oh yeah, which school did you apply to?"

"Kuoh Academy."

"Gah?!"

When I answered, Kuroka dropped the controller for the Rpg game she was playing—ah, the Large dragon killed her...

"Wh... why would you apply to that devil and supernatural creature hotbed?!"

"What do you mean why? It's closest to home, my grades are fine for it, and you're the one who said the devils there don't cause any real problems."

Okay, that's a lie, sorry—I mean, what I said wasn't false, but the real reason was wanting to be part of the original story's setting.

"Mmm, did I really say that? Hey, any chance you'd consider changing schools even now?"

"Whoa, why the sudden change?"

"It's... just... intuition?"

Her eyes are darting around like crazy... This might be the most flustered I've ever seen her.

The reason is obviously about her sister, but I couldn't help giving her a suspicious look. Misunderstanding that expression, she said, "Ugh, fine, I'll come clean since we've gotten this far..." and started explaining the real reason she came to this town.

Her parents (especially her father) were problematic people who died early.

To protect and raise her sister Shirone, she became a reincarnated devil under a contract with the high-class devil Naberius, who had connections to her father, with the condition that they wouldn't lay a hand on her sister.

The surrounding devil families and retainers kept dying under suspicious circumstances after being forced to participate in strange experiments.

Her master ignored the contract and tried to force her still-young sister to learn senjutsu despite the mortal danger.

She killed her master and tried to escape with her sister, but pursuers were sent after them unnaturally quickly, and they got separated.

After they were separated, she learned her sister faced persecution and nearly got executed, which filled her with guilt.

She came to this town to check whether her sister, who had become part of the Gremory family, was in danger or being mistreated.

Her sister now goes by Toujou Koneko and attends Kuoh Academy's middle school, so she was worried that when her sister advanced to high school, someone would discover her presence.

...I already knew these facts. But hearing her tell it herself with that somewhat dark expression gave her words a weight that text alone couldn't convey.

"Ahaha, I've really been going in circles with everything. The whole mess started when I made the mistake of relying on the organization my good-for-nothing father belonged to."

She gave a dry, self-deprecating laugh.

"But that's not entirely your fault, is it? When you're a kid, it's natural to try to rely on the adults around you for anything, and even gods or Maou(Demon king) couldn't live their entire lives making only the best choices."

"Maybe so... but that doesn't change the fact that I couldn't protect Shirone..."

"That's not true!"

No, that's wrong.

"What do you mean it's not true?"

"Because you're still protecting your little sister right now!"

"Huh?"

Ugh! She's seriously tilting her head like she doesn't get it!

"Sure, maybe things didn't go exactly how you wanted, but if you hadn't killed that master, your sister might have died from senjutsu training or those suspicious experiments. And if the Gremory family who took her in had turned out to be terrible people, then you coming to this town was definitely meaningful!"

"But! In the end, it was pointless!"

"That's just hindsight! It absolutely had meaning!"

We glared at each other for a while until Kuroka apparently decided this was pointless first. "Fine, whatever, I give up. I'm going to bed now," she said, wrapping herself up in the bed covers.

"Kuroka?"

"......"

No response. Looks like she's committed to sulking, so I had no choice but to wrap myself in a blanket on the floor and go to sleep too—just before I lost consciousness, I thought I heard a quiet "thanks" but I might have imagined it.

Time passed, the new year came (I even prayed for exam success at a Kyoto shrine), and we settled on having Kuroka cast a presence-concealing technique when her sister entered the high school division of Kuoh Academy.

The Three Perverted Idiots were studying for exams with deadly serious expressions—apparently believing that Kuoh Academy's high female ratio meant a dream harem awaited them.

They were so starved for anything erotic that they studied while having perverted conversations... pretty impressive multitasking.

Between exam prep and continued training, I successfully passed the entrance exam for my dream school, Kuoh Academy!

A few days have passed since I started at Kuoh Academy in April. I don't know how involved I'll get, but next year's going to be crazy... I was thinking about that when someone called out from behind me.

"Excuse me for the sudden question. You wouldn't happen to keep cats or know someone named Kuroka, would you?"

Koneko was standing there—why is she here (in the high school section)?!

Apparently the chaos surrounding me wasn't going to wait a whole year.

Ds: Looks like we're finally getting to the original story. It feels like it's been both long and short getting here—kind of strange.
