As soon as he touched her, he noticed her camisole was plastered to her chest with sweat and that the tips of those still-childish bulges were erect.
“Ahhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!”
He had lived with her for about a dozen years, but he had never heard her scream like that.
Her skinny body bent sharply backwards as if she were performing a bridge. She stuck her pelvis out so far it looked like it would break off, the bottom of her camisole slid up, and her petite navel came into view. She was his sister, yet Mutsuki found that adorable depression to be strangely alluring. He was so shocked he stopped his outstretched hand, but it was already too late.
“Hyah… Ah… Aheh…”
A sharp-smelling golden curtain spread from the depths of her trembling jeans and spilled to the floor.
He had not smelled this scent since his sister was nine and they had been tickling each other in the bath. As the liquid formed a wave, he realized what it had to be. His sister was so out of it that he grew pale, but then she finally passed out and collapsed limply to the floor.
He was utterly dumbfounded. He had not the slightest clue what was going on.
And then…
“Kyuji… Bchu… Ahhh…”
“Eh?”
After being attacked by inhuman foes a few times already, Mutsuki quickly realized what this voice was.
The unpleasant groan was as high-pitched as fingernails on glass. A moment later, it showed itself. A black slime-like creature burst from his wet clothes.
(One of those things was still there!?)
A scorched stench hung around it, but it fell between Chiaki’s limp legs and moved itself forward. Mutsuki trembled in horror as it sent ripples through the spreading puddle and gradually grew in size.
It was absorbing the urine to grow.
After drinking it all and leaving the wooden floor perfectly clean, it moved toward Chiaki’s jeans in search of more liquid.
“S-stop!”
“Kyubi? Kyugahhhh! Agyahhhh!”
He thought his legs would give out again, but he frantically picked up his unconscious sister and ran away.
The black filth cried and wailed in hunger as it crawled after him. What was he supposed to do? He decided to at least get Chiaki away and ran toward the entranceway.
“Yes. Good, good.”
A ball of red fire squashed the slime flat.
“Eh?”
The filth had burst to pieces from a flame hammer strike and it then turned to ash. Nothing remained afterwards. There was not even a mark on the floor.
“Walking around town with the Serpent’s Eye opened was pretty reckless, you know? I went out of my way to meet you at the station, but you ditched me.”
That flame had burned only the black water. The color was different, but Mutsuki had seen this just a bit earlier. He turned cautiously toward the voice.
“But.”
At some point a woman had appeared in the entranceway.
“You did a good job protecting your cute little sister, so I’ll skip the lecture.”
She too had flames growing from her back.
She did not have a giant sheet of metal, but her otherworldly aura still left Mutsuki in a daze.
His eyes first stopped on the healthy color of her skin. Its brown was gentler than a black person’s, so it more closely resembled a dark tan. It was a milk tea color that could not be reproduced with dyes or at a tanning salon.
Then, he noticed her outfit. She wore a miniskirt about as short as a waistcloth and a black cutter shirt that only just barely covered her breasts. While she was also wearing boots that rose halfway up her thighs and a long coat that covered her entire body, her outfit left her cleavage, midriff, and thighs entirely exposed, so it was hardly appropriate to wear around town.
She had red, almond-shaped eyes with a double eyelid, the deep-chiseled bridge of her nose stood prominently out, and her plump lips were a shade of red paler than her skin. Overall, she had the facial features of a model. Her wavy, waist-length hair was a glistening honey blonde, which added to her charm.
She was unmistakably beautiful, but that seductive atmosphere actually made the boy wary.
“Wh-who are you?”
Suspicious, Mutsuki stood in front of his unconscious sister.
Appreciation filled the brown beauty’s face when she saw that brave brother.
But when she looked the boy in the eye, she looked just as shocked as Chiaki or the neighborhood girls and women had.
“So this I the power of the one to be the origin. I guess I shouldn’t be surprised.”
“!?”
She crouched down a little and instantly moved right in front of Mutsuki.
She had moved too quickly for him to follow with his eyes and she grabbed his cheeks before he could even gasp.
“Be closed. Humans are happiest as humans.”
“Wah!”
An itching sensation raced through his right eye, but it was much kinder than the pain from before. The boy frantically pushed her hands from his cheeks. He tried a little too hard to back away and his knees gave out. He landed on his butt next to his sister.
“Wh-what did you just do?”
“Oh, you’re pretty cute. I like this a lot better than that snake eyed”
The boy snapped back at her due to the responsibility of having his little sister so nearby, but the woman dodged his question with a gentle smile. She then threw some kind of key his way.
The keychain had a small hand mirror attached, so he looked into it.
“…Ah.”
His usual face was back. Everything was back to normal, right eye and all.
Noticing the tension leave his face, the woman smiled his way again. His heart skipped a beat when he looking at her again and realized how beautiful she was.
“The world has begun to move.”
She whispered to him with a meaningful alto voice.
“The world has begun to move with you at the center.”
“Eh?”
“Gather heaven, earth, and hell and you will have everything. The entire world is revolving around you.”
That was when he realized something else.
“I’ll explain what’s going on, since I’m sure you’re frightened with all this strange stuff happening.”
He recognized the strangely cute yet mature alto voice.
It was the voice he had heard over the phone earlier.
“Would you mind going on a date with me?”
After removing both Mutsuki’s tension and caution, she gave him a playful wink.
The woman said her name was Jiyuuni Micha and Mutsuki decided to believe her for the time being.
At the very least, she was not his enemy. Or so he thought. She had told him to run away over the phone and she had defeated that slime with her fire. She had even made sure to give Chiaki a bath while the girl was still unconscious, so he decided to trust her for now.
Although it mostly came down to wanting someone to explain what was going on.
Micha dressed Chiaki and laid her on the sofa and Mutsuki left with Micha after his older sister returned home. He was riding on the back of Micha’s motorcycle. It seemed to be an off-road motorcycle because its tires were as thick as a car’s and its long frame had no extra accessories.
He quickly regretted climbing onboard.
“Waaahhhhhhh! J-J-J-J-J-Jiyuuni-san! Too fast! You’re going too fast!”
“Call me Micha. Jiyuuni is a fake name for the human world, so I’m not used to responding to it.”
“Fine! I’ll call you Micha! But this is too fast! I’m going to fall off!”
“Then hold on more tightly. Just to be clear, you’ll definitely die if you fall off.”
He could only tremble as they moved so quickly the surrounding cars did not seem to be moving at all, but the woman did not slow down in the slightest.
In fact, she seemed to be enjoying this. When she saw him on the verge of tears, she laughed happily and squeezed the throttle even further.
“Uuh…”
He would normally have been too embarrassed to grab onto a woman he had only just met, but his life was on the line here. He wrapped his arms around her narrow waist lest he be thrown off the motorcycle entirely.
