A supporting character in a romance anime? I became a god using a rat talisman.

With this, he could leave this inexplicable future and return to his own world.

As for what the world will become in the future, that's none of his business.

"Let's make a deal. Use this card to send me back, and I'll pretend that thing in the pit never happened, okay?"

"Really?!"

Boqi's eyes lit up instantly.

"As long as Dad is sent back... he won't have to commit seppuku to atone for his sins? He won't have to be kicked out of the house? He won't have to be hung on a street lamp as a public spectacle?"

"Need not."

Qianyu nodded, and even kindly added a comment.

"And I won't tell that old man in this world... I mean, my future self. Let's pretend this never happened."

Upon hearing this, Pochi-chan finally realized that the father in front of her was a younger version from a parallel universe.

However, regardless of which world's father it was, as long as it could absolve him of the crime of patricide, Pochi would naturally be more than willing.

Then Pochi immediately began chanting.

"The Return!"

As magic was infused, the card transformed into a giant halo of light, hovering in mid-air.

At the center of that halo was a deep vortex of spacetime, with countless flowing lines faintly visible—paths leading to the past.

A powerful suction force emanated from the vortex, causing Qianyu's clothes to flutter loudly.

Just as he was about to step into the passage, Yili seemed to suddenly remember something and asked a question as if by some strange impulse.

"That...Dad?"

Perhaps because the crisis was over, this girl's thought process started to wander in strange directions again.

Since he was the father in the past...

Does that mean he can solve some problems that his current father can't?

For example... that terrifying battleground?

"Since you're already here...won't you come in for a visit?"

Pochi asked hesitantly, his eyes filled with a hint of probing.

"The mothers... would be so happy to know you're here..."

"Mothers...?"

Qianyu stopped in her tracks.

He turned his head, looked at Poch, and processed the word.

If he heard correctly, the girl used a plural form just now, right?

This is quite a lot of information.

So, my future self not only built a harem, but also married them all?

And judging from their tone, these women actually live together?

The scene was so beautiful that Kazama Chiba felt her scalp tingle just imagining it.

"Don't go."

Without any hesitation, not even for a second of thought.

Qianyu resolutely refused.

He had absolutely no interest in this development, which sounded like a harem anime.

How many romantic debts his parallel world self owes is that of that conman Yu, what does it have to do with him, a pure high school student who is only seventeen years old?

Moreover.

He is now just a single aristocrat who wants to gather power and pursue absolute freedom.

Those kinds of family dramas filled with mundane details and backstabbing are best left for the future, when that future middle-aged office worker can enjoy them slowly.

After saying that, he ignored Pochi's instantly crumbling expression and turned to walk towards the radiant spacetime vortex.

In the last moment before his body was about to be engulfed by the light.

He turned and took a deep look at Koji Kazue, who was still crying in the corner because of her sister's departure.

The cause and effect have been resolved.

That little girl has grown up.

He is now merely a passerby in this long period of time.

Ultimately, they will have to walk their own path in the future.

With this cause and effect resolved across time and space, Qianyu's figure completely disappeared into the light, leaving behind the future year of 2038.

……

"Om-"

After a brief period of mild tinnitus.

Before the dizzying feeling unique to time travel had completely subsided, the clamor of voices surged in like a tide.

Qianyu opened his eyes.

What comes into view is a bustling crowd, cosplayers in all sorts of outlandish costumes, and the huge exhibition hall of the Kugawa Comic Exhibition.

He glanced down at the clock on the wall of the venue.

July 29th, 10:10 AM.

It seems the card return sent him back to the place where he left this world.

"call……"

Qianyu let out a long breath; the feeling of being grounded finally relaxed his tense nerves.

However, now is not the time for sentimentality.

Now that we know the future script, we have to fill in the plot holes that haven't been filled yet.

He didn't linger at the comic convention; instead, he walked quickly out of the venue against the flow of people.

A few minutes later.

That familiar street, that somewhat dilapidated alleyway.

A little girl who looked somewhat down on her luck was squatting on a flower bed by the roadside, clutching tightly in her hand the few banknotes that the older boy had given her earlier.

She was still in a daze, wondering why that person had given her such a complicated look.

Suddenly a pair of familiar shoes came into her view.

"Big brother? Why are you back again?"

Xiao Yihui looked up in surprise, her clear eyes filled with confusion.

"Did you forget something?"

Qianyu ignored her question.

He stood a few meters away from the girl, his gaze not on her, but on the empty air behind her.

"Come out, karuta!"

The air was eerily quiet.

Only the faint sound of traffic from the distant streets could be heard.

“I know you’re here.”

The sealing staff in Qianyu's hand was already in her palm at some point.

"This is your only chance to negotiate. If you don't show up now..."

He paused, his tone suddenly turning cold.

"The next time we meet, it will be a forced seal. At that time, no matter who you want to protect or where you want to go, it will be out of your control. Don't blame me for being merciless."

This blatant threat worked.

Just as Ichie was looking blankly at someone, not knowing who her older brother was talking to.

The air behind her suddenly distorted.

Countless purple musical notes appeared out of thin air like fireflies, and then quickly gathered into the figure of a girl wearing a white dress.

That's a geisha card.

At this moment, she lacked the composure and calmness she would have in the future; her face was filled with tension and unease.

The karuta glanced at Chiba with some fear, then, as if it had made up its mind, slowly floated down and stood in front of the bewildered little girl.

"Truly worthy of being... Lord Kuro's successor."

Just as she described in her future self.

The chorus card did not attempt to resist, nor did it try to escape.

She simply lowered her head in a humble, almost groveling manner before the boy she had only met less than a minute ago.

“I have no ill intentions. I’m only staying here because this child is too young. She just lost her parents and has no relatives. If I leave too, she really won’t be able to survive.”

"So please... let me stay. Even if it's just as a card, even if it has no physical form... as long as I can watch her grow up, as long as I can take care of her until she reaches adulthood... even if you don't come afterward, I will still come to you and willingly be subdued by you."

I promise you.

Qianyu suddenly spoke, interrupting her spellcasting.

"Huh?"

The karuta was stunned.

She had prepared a whole host of words, countless reasons, and was even prepared to kneel down and beg for mercy.

The other person... answered first?
