Kashi, with her eyes closed, gradually settled into a steady breath.
The Tanaka home fell into silence as the busy day drew to a close.
"No, this is wrong!"
Kashi suddenly opened her eyes and sat up in bed.
"I still need to collect magic stones and rebuild the Demon Realm. How can I sleep?"
She clenched her fists, her face full of remorse.
"The human world is truly terrifying; a moment of carelessness can lead one to indulge in pleasure.
Kashi, oh Kashi, you must pull yourself together. The Demon Realm and Lord Demon King still need you."
After boosting her own morale, Kashi got out of bed, wearing slippers and pajamas adorned with cute cat designs.
She opened her door, poked her head out, and looked left and right.
Only after confirming no one was there did she carefully step out.
She tiptoed to Tanaka Masao's door, ensuring she made no sound.
Upon reaching Tanaka Masao's door, Kashi did not make any immediate moves.
Instead, she first bent down and looked through the gap under the door.
When she saw that the light in the room was off, she quietly clenched her fist in a silent cheer.
"Nice!"
Once she confirmed Tanaka Masao was asleep, Kashi turned the doorknob.
"Hmm? Why won't it open?"
Pushing the door, Kashi realized it was locked.
"Damn it, it's bolted from the inside. Who is he guarding against at home? He must be doing something bad in there."
However, Kashi was not discouraged and took out a magic stone.
"Good thing I came prepared."
Some of the magic power in the magic stone had recovered, enough for Kashi to cast a few small spells.
A strange light glowed at the door lock.
"Magic: [Unlock]"
Though called magic, it was actually just controlling magic power to open the lock, like an invisible hand.
With a crisp "click~" sound, Tanaka Masao's door was successfully opened.
Kashi slowly pushed open the door and stepped inside.
As a demon, even without the enhancement of magic power, Kashi still possessed excellent night vision, her golden eyes reflecting light in the darkness.
She approached Tanaka Masao's bed and looked at him.
Listening to his snores, Kashi shook her head.
"He's really a deep sleeper, but that just makes things easier for me."
At this moment, she once again sensed a powerful energy at his chest, undoubtedly her target.
She reached out and gently pulled back Tanaka Masao's blanket.
Fortunately, Tanaka Masao hadn't pressed down or gripped the blanket, allowing Kashi to quickly pull it down.
The blanket was pulled down to Tanaka Masao's waist, just covering his navel.
Looking at the glowing, triangular crystal embedded in Tanaka Masao's chest.
Kashi's eyes were filled with delighted affection.
She murmured,
"My little darling, you are truly beautiful. You must have suffered following this Tanaka Masao fellow. Come, follow me, and I will cherish you well."
Kashi said this not because she had any strange fetish.
Rather, in her view, this armor had something akin to a spirit within it.
So she needed to build a good relationship with the spirit first, to gain its approval.
Kashi showered it with praise, then reached out and gently stroked the armor core on Tanaka Masao's chest.
Indeed, she felt no rejection.
"Oh, my lovely little darling, hehe~"
...
On the other side, Tanaka Masao, in his sleep, felt someone on his body.
As he was about to wake up, he vaguely heard someone whispering.
"My little darling, you are truly beautiful. Come with me, I will treat you well."
Tanaka Masao: ?
He struggled to open his eyes and looked in the direction of the voice.
He saw Kashi leaning over his bed, her small hand placed on his chest.
Tanaka Masao: QAQ
His mind instantly cleared, somewhat confused by the current situation.
"Am I being night-raided? Should I lie still and enjoy it, or take the initiative?"
After a moment of hesitation, Tanaka Masao decided to observe.
If Kashi really intended to do something, he would suddenly wake up when she was most relaxed.
Just thinking about it was interesting, hehehe.
Tanaka Masao, while lost in his fantasies, kept an eye on Kashi.
Soon, he realized something was wrong.
Because Kashi didn't seem to be after him, but rather the armor core on his chest.
She was simultaneously sweet-talking the armor core and already starting to try and pry it off.
"Damn it, she's not after my body. How infuriating!"
Tanaka Masao expressed his displeasure.
To prevent the armor from harming those around him, he had set up the armor system back then.
It would not attack his family, and it would not activate on its own unless his life was in danger.
This was why Kashi could try to remove the armor here without being harmed.
Tanaka Masao was very angry now and needed to vent some steam.
And the target for this venting was naturally Kashi.
He continued to feign sleep, rolled over, and turned his formerly supine body to face Kashi by the bed.
...
Kashi, who was intently trying to remove the armor core, was startled by Tanaka Masao's sudden movement.
Only after confirming he had merely rolled over did she breathe a sigh of relief.
She continued her busy work.
Just then, Tanaka Masao's hand suddenly reached out and rested on Kashi's back.
"Eek~"
Kashi's body suddenly trembled, and she instinctively gasped.
However, she reacted quickly, immediately covering her mouth to prevent herself from making a sound.
She looked at Tanaka Masao, found he was still sleeping, and then relaxed her guard, assuming he had just rolled over and his hand had casually landed there.
What Kashi didn't notice, however, was that Tanaka Masao, who had been soundly sleeping and snoring, had stopped snoring.
Feeling Kashi cautiously try to remove his hand, Tanaka Masao's lips curled into an imperceptible smile.
His fingers slowly began to move.
Tanaka Masao's hand was already placed on Kashi's lower back, at her waist.
As is well known, the waist is a very sensitive area.
So when Tanaka Masao's fingers moved, Kashi reacted.
