Chapter 2: Little Sister's Responsibility
"Shido, what are you thinking?"
Kotori asked worriedly.
"It's nothing, go ahead!"
Shido shook his head and didn't think about it any further. After all, what was more important now was Nia's discovery, so he had to write down what he thought of just now and analyze it when he had time.
"Alright, Nia tried searching if there's a Spirit in this world, and she found several names, including 'Rinne and Rio' from earlier…" Kotori explained softly, then said with a worried tone: "But when she discovered a certain name [Ren], she got into trouble…"
"What do you mean, trouble?" Shido asked anxiously.
"Apparently, that Spirit named [Ren] wasn't happy about being searched, so she called Nia's consciousness out at night to have a talk." Kotori elaborated.
"What kind of talk?" Shido frowned. It certainly didn't feel good to have his girlfriend summoned by someone else at night.
"Dunno. Nia only asked if you knew a wife named Rinne and a daughter named Rio."
Kotori gave a wry smile.
Shido had no idea why Nia didn't say everything. Was it because she was threatened by that certain Spirit, or was it for his own good…
"Anyway, that's everything for now."
Kotori felt thirsty after talking for so long, so she walked to the kitchen, getting herself a bowl of papaya milk from the fridge. She asked Shido to buy it for her so that she could drink it and see if it makes her chest bigger.
While she was drinking papaya milk, Shido was thinking about everything she just said.
Rinne and Rio could be searched, but that certain one named [Ren] was even above them?
If so, why would she allow Nia to know about Rinne and Rio? Could it be a fight between Spirits of this world?
But no matter how hard Shido thought, he couldn't think of an answer, and he had to go to school tomorrow morning, so he went to bed after thinking about it.
...
"Oni-chan, get up quickly!"
"Nani the f…!"
Shido let out a scream as he saw Kotori kick his stomach. He was confused: He made sure to set up the alarm clock, so why was Kotori waking him up?
Fortunately, Kotori's kick didn't hurt that much, it was even a little comfortable for him. But, the premise was that she had to aim a little better. If she kicked a certain part of his body, he might not be able to have children, which would destroy the happiness of every Spirit.
For the ultimate happiness of his girls, he had to figure out what the hell was going on.
"Humph!"
Shido suddenly jumped up, hugged Kotori, and laid down with her.
"O...Oni-chan, let me go!"
Kotori struggled.
"No, I'm going to hold Kotori, and I have something very important to ask you."
Shido shook his head. The feeling of holding Kotori was very good, very comfortable, and it could prevent her from escaping.
Listening to the soft and cute voice of his little sister, Shido could be sure that the other party was the White Ribbon Kotori, which aroused his inner desire to bully her…
"Hahahahahahaha….. Oni-chan, don't... stop!"
Kotori twitched as she was gasping for breath. Her big brother was tickling her, and there was nothing she could do about it.
"What's wrong?"
Shido asked with a smirk, and at the same time he stretched out his hand to Kotori's lower abdomen…
"Stoppppppp...Hahahaha…..it will kill me…Hahahaha…..!"
Kotori kept laughing and couldn't stop.
"All right..."
Shido stopped reluctantly. The feeling was so good that he felt a little reluctant to give up, but seeing Kotori's rosy cheeks made him realize that he had done enough, so he stopped quickly so that he wouldn't be able to lose control.
"Oni-chan, what do you want to ask..."
Kotori asked helplessly as she couldn't escape at all. If it was the Black Ribbon Kotori, she might figure out a way.
"What happened to my alarm clock? I clearly set the alarm, so why didn't it go off?"
Shido asked curiously. In fact, he didn't care much about the alarm clock, he just wanted to find a chance to get back at Kotori, though he was already used to her waking him up like that.
"Because I turned it off!"
Kotori said naturally.
"Why did you turn it off?"
Shido asked incomprehensibly.
"Because it's ringing!"
Kotori responded.
"That's the whole reason why I ..."
Shido said angrily.
"But it's the little sister's responsibility to wake Oni-chan up!"
Kotori retorted in disbelief.
"My sister has no such responsibility. You are not an alarm clock."
Shido shook his head and said in denial.
"Your little sister is the alarm clock! I don't care, I just want to wake Oni-chan up!"
Kotori shouted coquettishly.
"This... Forget it, just make sure to kick me more accurately."
Shido smiled indulgently. There was nothing he could do, since his little sister was too cute, and he must tolerate some small willful demands.
"Great, Oni-chan, get up! I've prepared a hearty breakfast for you!"
Kotori jumped up excitedly, escaped the embrace of Shido, and left Shido's room with a hop.
He smiled and shook his head. He didn't expect Kotori to make breakfast again. Was this also the so-called sister's responsibility?
If it was true, then he just wanted to say...it's great to have such a sister!
After breakfast, he found Kotori walking over with his school uniform. He looked at her in confusion, not knowing what his little sister wanted to do...
"What's the matter? Holding onto my school uniform."
Shido asked suspiciously.
"I want to help my brother get dressed!"
Kotori said naturally.
"Is this also my little sister's responsibility?"
Shido asked curiously.
"That's right."
Kotori nodded affirmatively.
"All right..."
Shido didn't reject the other party's good intentions, after all, she was just helping him dress up. Feeling her soft little hands gave him a wondrous experience.
"Oni-chan, you got everything?"
Kotori asked while helping to button up.
"I don't have anything special to bring, so yes..."
Shido responded casually, but was still contemplating: What happened to Kotori today?
Kotori's behavior was a bit weird. Although the White Ribbon Kotori was supposed to be meek and cute, the current one was way more active, so much so that she woke him up, made breakfast, and helped him put on clothes. None of these was necessary, but she did them all anyway.
Shido felt a little weird about this. You know, Kotori was now one of his girlfriends, so he kept telling her not to pretend to be his little sister; after all, they were not related by blood.
He didn't mean to cut off the brother-sister relationship completely, but he did feel awkward kissing her with the knowledge of her being his little sister.
So recently, when the two were together, they rarely addressed each other as brothers and sisters. Generally, they would call each other by names. However, the White Ribbon Kotori always called him "Oni-chan"; after all, old habits die hard.
Unexpectedly, today's Kotori had been showing her identity as his little sister and doing a lot of things that a little sister was responsible for. Did someone stimulate her?
"Did Mana say something to you?"
Shido asked curiously.
"Huh? Why would Mana say anything? No, Oni-chan..."
Kotori lowered her head in embarrassment.
"Figured."
Shido said with a wry smile.
"It's really nothing..."
Kotori shook her head.
"It's about little sisters!"
Shido said with certainty.
"How did you know that, Oni-chan?"
Kotori looked at Shido with a surprised expression. She didn't expect him to figure it out this quickly.
It's so obvious!
Shido wanted to say this very much. White Ribbon Kotori was too innocent and cute, but after thinking about it, he still didn't say it directly. Instead, he asked the question carefully:
"What did she say to you?"
"She said that as your little sister, she felt bad for not being able to see you or take care of you, so she asked me to fulfill her responsibilities as a little sister for her..."
Kotori replied softly.
"This is so..."
Shido looked at her in amazement. This was unexpected, really unexpected. He was initially worried that his two sisters started a quarrel that he didn't know about, but actually, they were trying to figure out the best method to care for their mutual brother!
PS: Having siblings must be fun, huh?
