At 8:49 PM.
*Knock Knock*
"Kamiki-kun, may I come in?"
"The door isn't locked."
"Excuse me...?!"
As she opened the door, Kosaki was stunned to see Eiji doing push-ups wearing only pants.
His lean muscular body and masculine scent filled the small room, causing her face to blush instantly.
Covering her face with her hands, she spoke nervously and embarrassedly.
"Kamiki-kun, what are you doing?"
"1998, 1999, 2000!"
Finishing the count of push-ups, Eiji stood up, his body sweating.
"Just doing my routine to keep my body from rusting."
Taking a bottle of water from the table, he drank it all in one go.
"Wuah... Wuah... Wuah..."
Through her fingers, Kosaki was amazed and couldn't look away.
Even the guy she liked, Ichijo Raku, had a body like an ordinary high school student.
"Kosaki-san, what are you looking for?"
Kosaki just stood in front of the door, bewildered, which confused Eiji.
"Ah, you must need to use the bathroom."
After realizing, Kosaki remembered her purpose for coming.
The Onodera household was only occupied by a mother and two daughters without a male figure. So, to prevent incidents like entering the bathroom while it's in use as in ecchi manga, it was decided that the three women would bathe first, and then Eiji would have his turn.
"I see. Um, I'll take a shower after cooling down a bit."
"In that case, I'll go back to my room. Good night, Kamiki-kun."
"Good night."
Not wanting to be seen as a perverted woman, Kosaki hurried back to her room.
"Her face is a bit red, could she be sick? Oh well, it's not my concern anymore."
Not thinking too much about Kosaki's abnormal behavior, Eiji took the towel and change of clothes he bought at the supermarket earlier, then went to the bathroom.
Going down the stairs, he crossed paths with Haru wearing pajamas.
"Ah."
Haru also saw him and turned around, avoiding him.
"..."
Regarding this, Eiji was already used to it. For some reason, Haru kept her distance from him, and their relationship wasn't like before.
Because it was the decision of others, he respected it and didn't try anything.
Arriving at the bathroom, Eiji took off his pants and put them in a special basket. Then, he stood under the shower, letting the cold water soak his body.
"With my presence, I want to know how Suguru-san started the Hyakki Yako (The Night Parade of a Hundred Demons)."
The plot of Jujutsu Kaisen 0 had started, and Eiji knew that Geto Suguru would launch a terrorist attack by releasing a thousand Cursed Spirits in Kyoto and Shinjuku on December 24, 2017.
However, that action was only to divert Gojo Satoru's attention, while his main goal was to absorb Orimoto Rikka.
However, Suguru wasn't confident in defeating Satoru, that's why he devised this scheme.
With Eiji's addition to this world, Suguru had to prepare another plan, considering he also couldn't defeat him.
"Forget it, even if I don't do anything, Okkutsu Yuta will still win with the power of love. Suguru-san is destined to lose."
After finishing rinsing off, he soaked in the warm water leftover from the three women.
Japan was very water-conscious, and they usually wouldn't drain bathwater just because it had been used for a short time.
"The main problem is how I can secretly destroy Suguru-san's body without Satoru Nii-san finding out... If he finds out, it'll be very troublesome."
Resting his head against the wall, Eiji closed his eyes and relaxed.
If it were before, he wouldn't dare to act recklessly that would affect the plot, fearing it would change the future and he would lose the advantage of knowing the future. But now his mindset had changed; he would do anything without caring whether his actions would disrupt the plot or not, as long as he could survive, he didn't care even if it meant violating morality.
"Suguru-san's body will be very useful for Kenjaku. Whether it's the Culling Game, absorbing Cursed Spirits, or anything else, as long as I prevent him from getting Suguru-san's body, it will cripple most of his plans."
Although Suguru was his acquaintance, Eiji preferred to destroy his body rather than let it fall into Kenjaku's hands.
"If only I could find Kenjaku, everything would be easier. Unfortunately, that guy is very good at hiding. It seems that his two losses by the Two-Sided Specter bearers in the past have left a deep trauma on him."
Honestly, he really wanted to eradicate Kenjaku, who was the root of the tragedy in the world of Jujutsu Kaisen.
Without Kenjaku's presence, Special Grade Cursed Spirits like Hanami, Jogo, Dagon, and Mahito wouldn't be so organized, and they would cause chaos like ordinary Cursed Spirits. Thus, Eiji could deal with them easily.
"If I ever meet Kenjaku, I won't let him escape."
Considering Kenjaku's caution, Eiji felt the chances of them meeting were very slim.
"I've been soaking for too long."
Getting out of the bath, he dried his body with a towel and started to get dressed. After that, he went to the room on the second floor.
Seeing that it was already 9:10 PM, Eiji wasn't too sleepy yet. So he watched short videos while lying on the bed.
...
At 1:50 AM.
The residents of the Onodera household were fast asleep, including Eiji who was staying over.
"Toilet..."
One of the bedroom doors opened, and a girl walked slowly while yawning.
After answering nature's call, the girl was about to return to her room, but her gaze happened to fall on the men's underwear lying in the basket.
"Gulp."
The sound of swallowing saliva suddenly echoed in the quiet and serene bathroom.
"No no no, what am I thinking! I'm not a pervert."
The girl shook her head to dispel the absurd thoughts filling her mind.
"Ugh... Just once... It should be okay, right?"
After a fierce confrontation between the angel and the demon in her mind, she succumbed to the demon's whisper.
Poking her head out of the door, she made sure no one was coming.
Not forgetting to lock the door as insurance, she stared at the men's underwear with a hot gaze.
Extending her trembling hand due to nervousness, she picked up the men's underwear and brought it to her nose.
"Sniff... Sniff... Mhm~... So this is Kamiki-kun's scent, it's addictive..."
Closing her eyes to enjoy the scent of the men's underwear, her left hand involuntarily went down and slipped into the pants, and she began to masturbate.
"Ah~, Kamiki-kun, be rough, treat me like a slut~..."
The girl masturbated while imagining herself being treated like a slut by Eiji.
Within a span of 15 minutes, she had already experienced four orgasms, leaving her too weak to stand. It took her 10 minutes to recover, reluctantly putting the men's underwear back in the basket, she hurried to her room like a thief.
