What Do You Mean My Cute Disciples Are Yanderes?

(MC POV)

The next pair was Manami and Kiyomi, the both of them seem to have something to prove to each other or something with how intense their gaze were.

They had brought their fight to another part of the continent and had materialised their domains to their fullest potential, plunging that part of the land in both light and darkness at the same time.

On Manami\'s side, a blazing sun was floating behind her, burning everything around to cinders. Opposite her was Kiyomi who had a moon behind her instead, covering everything in a radius around her in darkness with only the moon and herself being visible.

The two of them had been launching fire and ice at each other for a while, the land beneath them freezing over and burning up constantly.

"Ufufufu~ It seems my cute little Kiyomi has grown a little~ To think that there would be a day where you would openly stand against me~" Manami giggled while summoning another sun, acting as though the two of them were just playing around instead of trying to kill each other.

Kiyomi responded by conjuring up a dark moon that ate up all light, "I\'m sure elder sister had expected something like this ever since I came here, hadn\'t you? You know that I would eventually be unable to stand playing second fiddle to everyone and try and overthrow someone."

"Ara, ara? I thought for sure that my little Kiyomi would be more focused on Master instead~"

"Really? Then explain how it is that your skills are a direct counter to mine?"

Manami\'s conjured sun shot out a beam of fire that directly clashed against Kiyomi\'s light beam from her dark moon, both attacks cancelling each other out without doing any damage.

Manami giggled at her, "Ufufufu~ Isn\'t this simply because we are sisters, my dear little Kiyomi? But if you would wish that I would give you a little bit of a challenge, then how about this?"

She raised her hand in the air and the sun behind her started to rise up higher into the sky, expanding in size until it was twice of what it was from before.

Kiyomi furrowed her brows and tried to do the same with her moon, only to realise that despite her best efforts. Her moon would not expand as quickly as Manami\'s was.

"Ufufufu~ I\'m sorry my little Kiyomi, but I had already made it such that your \'start\' would be slower than mine~" She giggled.

Manami\'s sun continued to expand until it was three times the size of its original and the surface started to bubble angrily, looking as if it was about to explode.

But then, on the surface of the bright white sun, dark spots started to appear on its surface that slowly spread itself across the entire star.

Manami frowned at the sudden change, clearly not expecting something like this to happen to her sun. She then turned to look at Kiyomi who was sporting a satisfied smirk on her face, evidence that this was part of her doing.

My red fox tilted her head, "Ara? What did you do, my little Kiyomi?"

"You may have altered the start of this, elder sister, but I am the one who determines how it ends. And it ends with me taking over your sun."

Sure enough, the sun that Manami had created lost its light and turned into a black sun that absorbed light instead, expanding Kiyomi\'s domain and eating away at Manami\'s.

Kiyomi started walking forward, both the black sun and the moon bearing down on my red fox disciple.

My white fox disciple moved the two celestial bodies together, combining them into one and causing everything within a hundred miles to be plunged into darkness.

The already barren land started to crack even more, causing several pieces of it to separate into pieces and drift away up into the sky.

The only place that even had any light remained was the small area around Manami, but even then the area was slowly shrinking in size as the darkness consumed her light at a steady pace.

At this point, it really did seem like Manami would lose this encounter but she did not look worried at all, she even clapped her hands together enthusiastically.

"Ara, ara! My little Kiyomi has all grown up now! How impressive! But I\'m afraid you\'ll need to do a little bit more than that if you wish to beat me~"

Kiyomi frowned at her, "What do you me--"

Before she could even complete her words, the ground underneath Kiyomi suddenly broke apart and she was sent flying up into the sky alongside the other debris. My white fox was so surprised that all she could do was to cling on the piece of earth as she was shot into space.

Manami even had time to wave at her with a smile before Kiyomi was declared to have lost because of being outside of the battle area.

I have to say though, even if Manami did not rely on the ring out rule to claim the win, sending Kiyomi up into the sky would have granted her enough space and time to reverse Kiyomi\'s domain and reclaim control over the black sun and moon, turning the tables back in her favour.

This time, I was prepared when Kiyomi appeared outside the World, still looking quite disorientated by the sudden change of location.

"Kiyomi," I called out, getting her attention.

She turned back and her face darkened slightly, "Master… My apologies…"

I shook my head, "It\'s no fault of yours, you held your own against Manami and even managed to push her to a corner. If it wasn\'t for the rules that decided the loss for you, you could have went back and continued the fight, so you can\'t say that you are weaker than your sister. In fact, I do believe you have come a long way as well."

Unexpectedly, she shook her head, "No, no… I know what I\'m capable of, Master. I feel no shame in losing to my sister. I have always looked up to her for a reason, after all."

"Eh, then what are you apologising for?"

"For not being able to hold back anymore…"

I only just noticed the wet stain near her thighs which was proof of her arousal before she leapt at me, her lips wrapping around mine.

Ah… That\'s right, she\'s still in heat…

Guess I\'ll have to take care of that first…
