If more and more girls joined this family in the future, Shiina Mahiru felt it would be difficult to maintain harmony.
Goodness, even Yukino was taken care of.
She had already handled her.
Now he had even gotten involved with her two half-sisters.
However, despite her inner resentment, Shiina Mahiru quickly explained to Shiina Shinatsu.
"Of course, I haven't been deceived by him. Actually, Mu-kun is a very good person. Besides being a bit lustful, he's very gentle and responsible."
Shiina Shinatsu looked at her little sister with an unreadable expression.
"But this is the behavior of a scumbag, how is that good?"
"En, because Mu-kun has a special identity, he can have multiple girlfriends. older sister Zhenbai, you'll understand later."
Shiina Mahiru replied mysteriously.
Lin Mu was a demon. Although he was very bad, wasn't that the style of a demon?
Moreover, with her help in watching over things, nothing major would happen.
Even if Lin Mu left someone half-dead, with her current ability, she could still heal them.
Shiina Mahiru was exceptionally doting on her man.
Shiina Shinatsu, on the other hand, looked depressed, then said indignantly:
"What other identity could he have? I think you've just been fooled by him. Having multiple girlfriends, does he think he's a light novel protagonist? I think he should be reported to the police and arrested, so he doesn't go after other girls!"
Shiina Mahiru looked at her older sister with a half-smile, "Then why didn't older sister Zhenbai call the police immediately? If I hadn't asked, you would have deliberately kept this matter to yourself, wouldn't you?"
Hearing this, Shiina Shinatsu's cheeks flushed.
"I… I just know how to lose… Because of Mafuyu, I tried to attack him, wanting to teach him a lesson, but he taught me one instead."
"But I won't give up so easily. I will definitely train hard, become stronger, and get my revenge!"
Watching the hot-blooded and confident Shiina Shinatsu, Shiina Mahiru was speechless.
"older sister Zhenbai, are you some kind of delinquent leader? Still talking about getting your revenge?"
"Ugh… I'm just expressing my unwillingness! Anyway, I won't compromise so easily! Sorry, Mahiru, even though he's your boyfriend, bullying Mafuyu is still wrong!"
"As your and Mafuyu's older sister, I have an obligation to properly educate him and make him mend his ways!"
"Alright, then good luck, older sister Zhenbai."
How else could Shiina Mahiru respond?
She could only encourage her little sister.
It was estimated that the one who would be taught a lesson would be older sister Zhenbai herself.
She said she wanted to teach Lin Mu a lesson, but Shiina Shinatsu herself wasn't confident.
She had always seen herself as a boy, just to establish a strong image and protect her sister.
But wasn't this also a kind of admiration for strength?
Due to growing up without a father and being mocked and bullied by other children, Shiina Shinatsu had an aversion to boys.
For this reason, she even raised Mafuyu to be a girl who feared men.
And as the student council vice president, she had to understand men for convenient management.
Then she became obsessed with hot-blooded shonen manga.
Like a certain Hiratsuka Shizuka, she looked brave and imposing, but was actually a softie who would crumble at a poke.
En, Shiina Shinatsu was a little better than Hiratsuka Shizuka.
She had to be defeated before she would soften.
As for Hiratsuka Shizuka, if you just mentioned her failed blind dates, she would immediately break down and start wailing.
After their conversation, Shiina Mahiru and Shiina Shinatsu parted ways and went home.
Then Shiina Mahiru arrived near Mizutaka (High School Name).
She was going to pick up her cousin, Mashiro.
Mu-kun said Mashiro had no common sense, and she was also quite worried.
Moreover, Mashiro had just arrived and wasn't used to it yet, and probably wasn't familiar with the roads.
Although she had asked Asada Shino and Aoyama Nanami to look after Mashiro, since the three were in different classes, they couldn't fully take care of Mashiro.
And Aoyama Nanami was truly busy, working several jobs as a single girl. Shiina Mahiru was genuinely afraid she would collapse from exhaustion one day.
Asada Shino was even a regular employee at Saionji Odoriko's shop. This girl, who was loved by no one and self-reliant, also needed to work.
So, picking up Mashiro, it was better for her to do it herself.
Arriving at the school gate, Shiina Mahiru immediately saw Shiina Mashiro, who was sitting quietly under a tree with her bag on her back.
So she quickly walked over.
"Sorry, older sister Zhenbai, I was a little late because of something. How are you? Are you adapting to your first day of class?"
Facing Mahiru's concern, Shiina Mashiro shook her head and stood up.
"It's alright."
Without saying much, she put her small hand into Mahiru's, letting her lead her.
Her being so self-aware also made Shiina Mahiru a little amused.
She really was a girl like a pet.
And, the necklace on her neck, it should be the amulet made by Mu-kun, right?
Holding Mashiro's hand, Shiina Mahiru walked towards home.
The two golden-haired, stunningly beautiful girls attracted an unusual amount of attention on the street.
Someone even crashed into a lamppost and fell off their bicycle because they were staring too intently.
Passing a convenience store, Shiina Mashiro stopped.
She directly pulled Mahiru inside.
Then, releasing her hand, she picked up a baumkuchen from the shelf, tore open the packaging, and stuffed it into her mouth.
Shiina Mahiru was startled and quickly took out money to hand to the clerk.
She awkwardly bought some baumkuchen and then quickly pulled Mashiro away from the store.
After getting away from the convenience store, Shiina Mahiru took a deep breath and looked at Mashiro, who was happily eating the baumkuchen, with a complicated expression.
"Mashiro, why did you just tear open the packaging? You have to pay for it before you can eat it."
"Money?" Shiina Mashiro tilted her head, looking confused.
Mahiru was dumbfounded.
What kind of life had her older sister Zhenbai lived before?
She didn't even know what money was?
Taking a deep breath, Shiina Mahiru patiently pulled out her wallet and showed her banknotes of various denominations.
"This is money, older sister Zhenbai. In the future, if you want to eat baumkuchen or other food from a store, you need to exchange it with the clerk. Otherwise, it's stealing, which is very embarrassing and will make people you know uncomfortable."
Hearing this, Shiina Mashiro nodded, looking at the banknotes in her hand as if she understood, yet didn't.
After a long while, she earnestly said to Mahiru: "Mahiru, thank you."
"No one ever told Mashiro these things before."
"And Rita always handles everything…"
She had forgotten that Rita wasn't with her.
So… the troublesome matters could only be left to the new owner.
Facing Mashiro's gaze, Shiina Mahiru felt a little uncomfortable.
She always felt like Mashiro was planning something.
But it must be her imagination, right?
Such a naive Mashiro should be very innocent, right?
However, what she didn't know was that a pet is a pet precisely because it has an absolute dependence on its owner.
Taking care of a pet is very troublesome.
Especially when this pet is a beautiful girl.
