Part 1

Hayashizaki Kanae is a swordswoman with the title of Storm Cat.

While she was a child, she had gone to many dojos and defeated them without a single loss. Her ponytail was like a black cat’s tail, waving in the air.
The strikes from her two-sword-styled kodachis flowed nonstop and were undoubtedly an infinite gale of swords.

Her fighting form was indeed fitting to her title of Storm Cat.

However, her sleeping face was like an angel.

The curtains were fully parted and the morning sunlight shone into the dark room. But even so, she still slept, like a sleeping princess, and showed no signs of waking. Her skin was white to the extent that the light made her cheeks glow. Her long, black hair was tied back and in a mess. Her usual, stern swordsman’s face was also innocent and relaxed.

…It had been a long time since he last saw her, and she had become cute since then. Kazuki looked at her, fascinated.

No, no, wait. This was not the time to look at his imouto in fascination.

“Hey, quickly wake up. Breakfast is already made.”

Hayashizaki Kazuki infused a loving gesture and shook her shoulders. Right at this moment ——

“—— Nii-sama, chance!”

Kanae’s eyes, whom he thought was still asleep, suddenly opened.

“What!?”

Kanae’s hands and feet were like tentacles and suddenly shot out from under the blanket.

Kanae’s soft and small hands and legs wrapped around Kazuki’s body. In just a short period of time, she pulled Kazuki onto her bed and tightly hugged him. Towards him, Kanae revealed a fearless smile.

“Nii-sama, being attracted by his imouto’s cute, sleeping face, had become careless. The bed is a battlefield for men and women. This is Hayashizaki-Ryuu’s Art, <Deathly Plant TemptationStrategy of Flower Attracting Insect>.”

“…Don’t just randomly invent a ridiculous art.”

Kanae, who was rubbing her face on his chest, flirted with Kazuki, who was stunned and sighed.

“The feeling of Nii-sama, the scent of Nii-sama, it has really been a long time. Even though, yesterday, Kanae finally had the opportunity to return home, Nii-sama was not willing to sleep with me. It must have been because you’re embarrassed, so Kanae thought of a scheme. As expected, you’re embarrassed, right?”

“I’m not embarrassed! …Really now. If it were in the past, it would have been fine. Right now, we are both high school students, and it is disgusting for siblings to be clinging together. I’ve already told you to not hug me!”

“Don’t treat Kanae’s pure, sibling love as something disgusting!”

Hayashizaki Kanae is a swordswoman. —— However, the fact that she is a severe bro-con was really her only drawback.

Although Kazuki wanted to escape and struggled, Kanae’s hands and legs that wrapped around his body firmly did not move. Her arms and legs were releasing a faint, blue light.

The reason the petite her could use such degree of strength was because she was strengthening her body with Magic.

While they were being noisy, the blanket slid off. —— Only then did Kazuki notice a frightening fact.

“…You, what are you wearing? Although it is already spring, what would we do if you catch a cold.”

Kanae was wearing pajamas where you could nearly see the skin underneath.

Her slim waist and round hips were clearly shown through the translucent fabric.

“What do you think, Nii-sama? This is the Kanae that has been upgraded into a female high school student. Since Kanae hadn’t seen Nii-sama for so long, it is the anniversary where she wanted to show her female charm to Nii-sama.”

Kanae, whose face was red, stuck her body onto Kazuki and began to rub on him. Her small boobs slowly changed shape.

The bed was a battlefield… Kazuki began to take deep breathes and calmed himself down.

“You are indeed my cute imouto… But, I will not generate any desires towards my imouto. Quickly, get off.”

“Ku. You only said cute, you actually still treat the matured lady, Kanae, as a child?”

“What matured Kanae, idiot. There is already no time left to be in bed, quickly get up.”

“Kanae is still asleep. Fu —— Fu —— ♪”

“…Still, this is my first time seeing such shameless sleepwear.”

“Kanae, who has not returned home for a long time, is a princess. So if you do not use a suitable method for waking up a princess to wake her up, Kanae will not leave the bed.”

“What method for waking up a princess? No matter what, you are still born and educated as a samurai.”

“Speaking of which, the method for waking up a princess is obviously a kiss, Nii-sama. Come.”

“Uwah, don’t come closer! Don’t bring your face closer!”

Kazuki tried again to escape… …However, sure enough, if he was to only use his physical strength, it was impossible to escape from his imouto’s magical clutches.

—— Helplessly, Kazuki could only also cast Physical Enhancement Magic onto his own body.

Drawing out energy from his spirit and allowing it to flow through his entire body. At the same time, heat gushed out from his body as Kazuki made his body awaken. In an instant, he broke away from Kanae’s hands’ and legs’ bind, and escaped from her bed.

If the conditions were the same, then he would definitely not lose to his imouto in terms of strength.

“Meanie!”

“What meanie? You were the one that first used Enhancement Magic, right?”

Once those cold words came from Kazuki, Kanae stared at Kazuki with puppy eyes.

“…Don’t make an expression as if you were a small animal that was abandoned. Really, I will forcibly make you get out of bed.”

Kazuki wrapped his arms around Kanae’s waist and gently picked her up from the bed. If this was the case, he should quickly finish the work of serving a princess. Kanae’s expression suddenly brightened up.

“Nii-sama! This is Hayashizaki-Ryuu’s Final Secret Art, Princess Carry!”

“Don’t randomly invent a Secret Art! We, Hayashizaki-Ryuu, do not have such a Final Secret Art!”

This person shouldn’t be looking down upon our school.

“This is nerve-racking, Nii-sama, really nerve-racking… The princess carry is almost like a dream… Even though it was so difficult to get up, Nii-sama had to do such a dream-like thing in the end… Is this situation what they call a heavenly vision…”

Kazuki, using a carrying posture, made Kanae, who had a dreamy expression, spin around.

“Okay, it’s over.”

“So short!? The feeling of floating in the clouds was only a fleeting moment!? It’s too short!!”

“Hey, before you eat breakfast, go change your clothes. That kind of appearance is scandalous.”

Kazuki placed Kanae down. She pursed her lips and threw a fit.

“…Because I am a princess, I cannot change clothes by myself. Nii-sama, please personally help me change.”

“Why did you suddenly say such willful words? Are you still playing at being a princess?”

“Because, didn’t Nii-sama say it yesterday night, since we have not met for so long, so you will do whatever is requested, right? Us swordsmen must keep our promises!”

I am already not a swordsman… Just when this sentence was about to come out from his mouth, Kazuki’s gaze fell upon the back of his left hand. An egg-shaped, elliptical pattern was imprinted there.

Enigma. It is an emblem from another world that changed Kazuki’s fate.

“Although, I said anything is okay, I did not imagine that you would put out requests such as kissing and helping you change your clothes. If we were to do such things as siblings, then it would not be skinship, but perverted acts.”

“Anyways, Nii—sama won’t generate any lust towards Kanae, isn’t there no problem then… Or, is it that Nii-sama wants to escape from Kanae’s arousing charm?”

Kanae revealed provocative eyes and raised both hands. Kazuki was outraged by this phrase.

Due to the challenge issued by his imouto, replying to all of it was his duty as her brother.

Using the mentality trained as a previous swordsman, Kazuki opened up his imouto’s pajamas. Just like peeling off thin skin, the snow-white skin was gradually revealed in front of his eyes. Kanae, *mojimoji*^[1], wriggled her body.

“I-It was seen… Kanae’s appearance of only wearing undergarments. I’m currently being seen by Nii-sama… Please carefully look after me…”

“Why are you excited? Are you a pervert? I didn’t see. I didn’t see it one bit. And even if I did see it, I will not generate any thoughts towards my imouto wearing only undergarments… Where is your uniform?”

Kanae pointed to the top of a table, a folded uniform was placed upon it.

National Knight’s Academy Caryatid’s Sword Division’s female uniform was a narrow-sleeves-kimono-styled blouse with a female hakama-style miniskirt, combining into an outfit that consisted of both Japanese and Western styles.

After helping Kanae put on the stern outfit, Kazuki was finally relieved and sighed.

“Okay. Compared to those kinds of pajamas, you are still more suitable for this type of clothing.”

This was the real swordswoman Storm Cat.

Having said that, all swordsmen like to consider their image; nicknames, sure-kill techniques, etc.

Kazuki also once had a nickname… But, this was already something of the past.

“This kind of Nii-sama, wearing a brand-new uniform, is also very, very suitable!”

Kazuki was wearing a different style of uniform than Kanae. Because, he was entering into a different division than Kanae.

He was wearing a blazer, which had an atmosphere of high quality, made from Alchemical Silk.

A dazzling, Gem System embroidery was embroidered everywhere. The metal parts of the belt and the metal buttons were made by intertwining a precious rainbow-colored metal called Marble Metal.

This was a male uniform that generously infused the true essence of Alchemy.

“A gentle Nii-sama coupled with an intellectual blazer is really a wonderful combination. This is the type that gives me the number one feeling of wanting to hug Nii-sama. Nii-sama, I love you —— Haah, haah.”

“Calm down, Kanae. As a Hayashizaki swordsman, you cannot lose your calm… Do not breathe raggedly in front of your brother.”

“But, although my appearance of wearing the uniform was praised by Nii-sama and made me happy, Kanae further hopes that Nii-sama would be more aware of the sexy undergarments earlier. Although I am your imouto, it is only in name…”

“Exactly, because you are an imouto in name, I have to be more mindful of it.”

Kazuki, who was once an orphan, was in a position where he was accepted as an adopted son by the Prestigious Ancient Sword Skill Family —— the Hayashizaki Family.

In other words, Kanae is the daughter of the family that he owes a great debt to.

“Even if it is only kissing on the cheeks, it is fine. I want Nii-sama’s kiss. So, sad…”

Kanae revealed an expression as if she had lost a duel and whispered. She placed two kodachis on her waist. She was already accustomed to the extremely heavy weight from the real swords. She turned her gaze towards Kazuki at the side.

“Nii-sama… Although you look very cool wearing the uniform… But, as expected, you won’t be bringing your sword?”

“How can I bring it? I am not a student of the Sword Division.”

Listening to the answer that left no room for debate, Kanae angrily glared at Kazuki’s left hand.

“It is all because that damn <Enigma> suddenly emerged on Nii-sama’s left hand!”

“It is already too late to talk about it… I already left behind the feelings of the sword.”

The people with magic qualities that were recognized by Divas will be awarded an Enigma on the back of their left hand at the age of fourteen, when their magic begins to grow.

People who owned an Enigma had to enter the Magic Division to study and were destined to form a contract with a Diva.

Hayashizaki Kanae is a Swordswoman. And Hayashizaki Kazuki from today on, is a Summoning Magic User.
