Chapter 28: I’m… my sister’s little sister?

The school that Xinghe and Yukina attended was called Yōkain Academy, a combined junior and senior high school.

The two girls were members of the Flower Arrangement Club and were currently inviting Mika to visit their clubroom.

Although Mika was also very interested in growing and caring for plants, she had to practice more at the Kendo Club for the next few days. Mika could only reluctantly decline.

Just then, a familiar voice called out from not far away.

“Yo, Mika!”

Although this was a voice she had never heard before, there were only a few people who would greet her with such a casual tone.

Aside from a few friends she made in junior high, the only people left were the classmates who were in the same class as her in both her first and second years of senior high.

And the only classmate who fit that description was Bai Shenxinghe.

But he wasn’t a girl. It was hard to imagine how he could have pitched his voice to produce a completely natural girl’s voice.

Moreover, he had happily gone home yesterday after borrowing two manga volumes from her. She saw no sign that he was planning a s*x-change operation.

Although suspicious, Mika instinctively turned her head toward the sound.

She didn’t see Xinghe, but she unexpectedly saw Yukina standing with her back to her not far away.

“Hmm?”

“Aiba-san, what’s wrong?” Seeing Mika suddenly stop, the female classmate beside her asked.

“Nothing. I just happened to see our club’s cute junior.”

“Oh, well, we’re heading to the club now, bye-bye!”

“Bye-bye!”

After a quick goodbye, Mika walked toward Yukina.

“Yukina!” Mika softly called out when she reached Yukina.

Noticing Mika’s sudden appearance behind her, Yukina flinched. After a moment of frantic commotion, she turned around and forced an awkward smile.

“Aiba-senpai! Ahaha, what a coincidence!”

“Yukina, what are you saying? We’re in the same club! It’s only natural for me to be here!”

“Aiba-senpai is absolutely right! Why didn’t I think of that?”

“Yukina, you seem a bit off,” Seeing Yukina’s poor attempt at playing dumb, Mika couldn’t help but wonder if she was hiding some unspeakable secret. “What are you hiding?”

As she spoke, Mika suddenly moved closer.

“Nothing, really nothing!”

Yukina hastily waved her hands to block her, but Mika still managed to see Charlotte, whom Yukina had been hiding behind her.

Seeing the petite and cute white-haired loli, Mika was briefly stunned.

“Wow, what a cute little sister!”

Charlotte was about to give Mika a friendly greeting but was suddenly glared at fiercely by Yukina beside her. She had no choice but to pretend this was their first meeting.

“Hello, big sister.”

“Such a cute little sister. Yukina, is she your sister?”

“Yes… yes, she is. I’m just showing her around the school.”

“But I remember you saying you only had a brother at home whom you hated?”

“Uh… she’s actually a relative’s younger sister, a distant cousin, who used to live in the countryside,” Yukina quickly explained.

“Oh, is that so?” Mika’s gaze returned to Charlotte. “What’s your name, little sister?”

“My name is Charlo—” Charlotte was about to say her name, but Yukina suddenly squeezed her small hand hard, seemingly warning her not to say her name from the other world.

“Char-what?” Mika pressed on.

“Char—” After several rounds of silent eye contact with Yukina, Charlotte finally came up with a new identity. “Xia Yin, I’m Bai Xia Yin! Nice to meet you!”

“So you’re Xia Yin! That’s a lovely name! My name is Aiba Mika, and I’m a senior in the same club as your sister Yukina. You can just call me Sister Mika.”

“Okay, Sister Mika!”

“Very good, what a good girl!” Mika affectionately ruffled Charlotte’s head.

Although Charlotte was internally disgruntled, she had no choice but to silently accept it for now.

‘This is so weird.’

‘Mika, who I’ve always treated as a good buddy with shared interests, is now affectionately ruffling my head. Can we still be friends?’

Seeing Mika and Charlotte miraculously hitting it off without a hitch, Yukina breathed a sigh of relief.

If it had been discovered that Charlotte was her brother, a witch who had traveled back from another world, Yukina truly wouldn’t have known what to do.

“By the way, is Xia Yin a student at our school too?”

“No,” Yukina replied casually.

“Then why is she wearing our school uniform?”

“Uh…” Yukina was at a loss for words.

She only then realized what a big mess Charlotte had caused by conjuring that outfit for herself.

At this point, she couldn’t even use the excuse that “their school uniforms look the same.”

It had to be said that Charlotte’s Projection Magic was incredibly powerful; she had perfectly copied the school’s unique emblem as well.

“Actually, she’s wearing my old uniform. All her clothes were in the wash and haven’t dried yet, so she had no choice but to wear my old uniform.”

“Is that so? I never would have thought Xia Yin would fit into Yukina’s old uniform so well!” Mika looked at Yukina’s overly prominent “snow mountains” and then at Charlotte’s sparse “little hills,” giving a mischievous smile. “Yukina, you developed quite quickly!”

“Not at all, Senior Aiba is quite well-developed too!”

Watching Yukina and Mika complimenting each other on their large breasts, the only flat-chested person on the scene was filled with resentment, feeling immensely offended.

“Don’t look down on me, Mika! I still have a lot of room for growth!”

“Hmm?” Hearing Charlotte’s defiant outburst, Mika was briefly stunned. It was only then that she realized the call she had heard earlier also seemed to have come from Charlotte.

The tone suggested she already knew her.

Mika was about to ask further when Yukina suddenly stepped between her and Charlotte with a big smile.

“Um, Senior Aiba, everyone else at the Kendo Club is waiting for us. We should hurry and go.”

With Yukina’s reminder, Mika finally realized she had almost forgotten the most important thing.

“Right, right, I almost forgot! Practice time is almost here. The captain and I aren’t there yet, the club president must be anxious! Let’s hurry over.”

After finally managing to send Mika off, Yukina shot a fierce glare at Charlotte behind her.

“Brother, can you say less? What if someone finds out you’re my brother who died in a car accident?”

“I couldn’t help it! Mika kept looking down on me!”

“Brother, why do you keep obsessing over your breast size? It’s going to corrupt all your efforts!”
