Shido flew into the sky once more as he observe the chaotic flames blazing in the sky.
"Kotori!"
Kotori who was having a hard time controlling her flames moved her head in front of her and saw Shido standing in front of her with worry covering his face.
"I-I'm okay. I am just having a bit of hard time controlling this power." Kotori replied to Shido acting like it was no big deal. She doesn't want to show her weak and dependent side to him in her commander mode.
In her commander mode, Kotori always kept a strong, charismatic and domineering front to cover her real weak personality. That's why Kotori didn't ask for Shido for help after they defeated Kurumi. Instead she kept everything to herself and focused on controlling her flames that is wrecking havoc inside her.
"You're clearly not okay!"
Shido shouted at her, angry that she tried to act alone when he was with her. He gritted his teeth and floated closer to Kotori. The flames that burned uncontrollably on the sky rushed towards Shido as if wanting to devour him but he was still in his Spirit Integration with Yoshino's Ice Spirit power so he could ignore some of those flames.
Still, despite having ice ability, Shido could still feel the burning sensation on his skin but he ignored that and came closer to Kotori since she was his priority right now. Even if his skin started churning black due to the burn Shido would still come to Kotori. Fortunately, he had transformed using Yoshino's Spirit form otherwise, even if he had amazing healing capabilities, Shido would still sustain some injuries.
"Don't..." Kotori could only weakly say those words since she was nearing her limit to became out of control. She was worried that Shido would be hurt by her like what happened 5 years ago that burned the whole Tengu City.
"Is your power going out of control?"
"..." Kotori didn't reply as she already closed her eyes. She was fighting hard the urge to let her powers to go out of control but she could still hear Shido and feel his presence that was already in front of her.
"Do you trust me, Kotori?"
Kotori could hear the calmness in his voice despite the blazing flames trying to engulf him. Kotori's eyes shed tears when Shido didn't abandoned her despite the danger of her powers. However, she also became determined feeling that determination in Shido's action.
Kotori nodded her head with the very last of her strength and uttered a word that could barely be heard.
"I... trust, Onii-chan..."
"Good, since you trusted me. I would never let my cute little sister be in pain."
Shido smiled gently hearing her almost unaudible voice.
Even though Kotori focus was preventing her powers from going out of control, her lips twitched slightly hearing Shido's words.
Just as she was about to think further and scold Shido, Kotori suddenly felt a pair of hands on her shoulder. The grip of the hands were gentle but she can feel the reassurance of security from those hands. Then she heard Shido's deep yet soothing voice that made her almost forgot that they were in a dire situation.
This action of Shido was very effective since the chaotic flames around Kotori calmed downed for a second. He know that this wouldn't last long so Shido had to seal Kotori's Reiryoku as soon as possible.
He tried to imagine all kinds of things that will happen once he seal her Reiryoku but Shido was sure that Kotori would definitely plant a powerful punch on his guts.
However, he didn't hesitate anymore and leaned his face forward towards his little sister.
Kotori who was momentarily distracted suddenly felt something soft on her lips.
It was soft and warm, but somehow, she felt that it was good. Kotori could feel the berserk energy inside her became subdued. The raging flames became calm like a lake.
Kotori could feel that her mind became clear again when her chaotic power became calm. She had now realized what happened and this was the tactic they use to seal Spirit Powers, however it didn't came to her mind that it would be her turn, and so soon.
Yet, Kotori didn't push Shido or let him go, instead, she indulged in this pleasant feeling on her lips.
She leaned her body closer and hugged Shido tightly.
Seeing this reaction of Kotori, Shido was first surprised but he let everything go and followed her action and wrap his arm around her delicate waist and continued kissing Kotori.
...
Below, in the ground. Tohka, Origami and Mana stared at the two kissing siblings in astonishment.
They didn't expect Shido to suddenly kiss Kotori, but what was even more surprising was that Kotori didn't push Shido, instead she receive everything with love.
"Siscon." Origami only said those words and continued watching the two.
"A-Ahahah. That might not be the case, Origami-san." Mana laughed awkwardly trying to think that it was only to seal Kotori's power that was on the verge of loosing control. However, like Origami, she didn't take her eyes off the two and couldn't help but felt envious of Kotori for kissing Shido.
Her face blushed when she had those thoughts then she shook her head firmly to erase those thoughts from her mind. 'No Mana! You are Nii-sama's biological sister! You can't have those thoughts!'
Origami saw Mana who had changing expression on her face but she ignored her since she didn't know what Mana was thinking about and focused on the two sibling in the sky.
"Mmmmmmrrrr..."
On the other hand. Tohka's cheeks was puffed like a hamster. She was pouting that Shido was kissing someone else again. But she knew that it was to save them. She know this since she herself had the same experienced. Thankfully, there was Shido, otherwise Tohka wasn't sure if she could still live carefreely and happily like right now.
In the end, she could only let out a helpless sigh and thought that she couldn't stop Shido from getting more girls. But still, she wouldn't allow anyone to get her position as Shido's girlfriend.
