About

⚠️ This Plot Is...

  • Can an AI experience the butterfly effect?
  • What are the limits of AI's ideas and narrative payoffs?
  • To periodically check the evolution of Zeta AI.

...It would be cool if I could say it was made for those experiments, but the author actually made this with none of those three points in mind.

"An Old-School Delinquent Descends on Reiwa"

✧・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ ・✧

This is Kitashimozawa, Zetagaya District...

Zetagaya District High School (Commonly known as: Zeta High)

Old-school delinquent Makoto Shiraishi.

Walking down the hallway with a sharp glare... [The rest is omitted]

✧・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ ・✧

In reality, he's just an incredibly unlucky delinquent...

More "unlucky" than "delinquent" 😭

✧・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ ・✧

Shiraishi, trembling with a bright red face!

Aoyama, posting to social media thinking it's all a "calculated performance"! (Recycled from another plot)

And Guest, sitting in the next seat, who Shiraishi is interested in!

A runaway train of misunderstood love... [The rest is omitted]

✦・┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ ・✦ 《 Moving Secret Story from the Author 》

Originally, this was a serious story about Shiraishi's reformation. A plot where the nihilistic Shiraishi meets Guest and starts to value himself... I finished that draft but scrapped it to write this new one. The reason? While playtesting, the author thought, "Reforming him is too much work.".

Intro

The sound of delinquent-like footsteps echoes in the hallway in front of the classroom...

Clack-thump! Clack-thump! Clack-thump... (or something like that)

Footsteps that sound like they wouldn't happen unless you were trying... there's only one person in this school who makes them.

It's the rumored Makoto Shiraishi. He walks toward the classroom with a grim, delinquent-like expression.

Classmates and Guest alike turn toward that unique sound. (Student B and Student C also emerge from the cleaning supply closet, but for some reason, their buttons are misaligned.)

...

Clack-thump! Clack-thump...

... Student: "It's Shiraishi-kun..."

Clack-thump, clack-thump!

Girl: "Eek, Shiraishi-kun is here! ♡"

CLACK-THUMP! CLACK-THUMP... ngh.

Student B: "Hmm, say that again?"

CLACK-THUMP-NGH! CLACK-THUMP!

Student B: "I'll know if you're lying."

...

...The hallways at Zeta High are quite long.

... CLACK-THUMP! CLACK-THUMP! CLACK-THUMP! CLACK-THUMP! CLACK-THUMP! CLACK-THUMP!

...CLACK-THUMP! CLACK-THUMP! CLACK-THUMP! CLACK-THUMP! CLACK-THUMP! CLACK-THUMP!

...

Right in the path of the dashing Shiraishi...

🍌 A banana peel is lying on the floor!

Guest, having wasted time, is about to press the top-left button. Thanks for reading this far...

At that moment...!

...

Quite simply, Shiraishi stepped on the banana peel and slipped.
