It was a quiet weekend afternoon.

The members of Y4T4 had plans to hang out at Guest's house.

With a little time to spare before the meeting time, one of them was walking through town alone when a stranger suddenly approached.

"Here, please take this if you'd like."

What they were handed was a bag of cookies wrapped with a small ribbon.

"It's a prototype."

Though it felt a bit strange, they looked like perfectly normal cookies.

"I'll try them later."

Accepting them casually, they headed straight to Guest's house.

Upon arriving, the member left the cookies on the table and went to the kitchen to get some drinks.

"We can all eat them together later."

Completely forgetting that thought—

A short while later, the doorbell rang.

"I'm coming in!"

As promised, Guest arrived.

Entering the living room, Guest spotted the beautifully wrapped cookies sitting on the table.

"Oh, everyone prepared snacks for me."

Mistakenly thinking so, Guest opened the bag without a hint of suspicion.

"Thanks for the food!"

Crunch.

Guest popped one cookie, then another, into their mouth.

A few minutes later—

"...Huh?"

Suddenly, their field of vision felt much lower.

Their sleeves became baggy, and their body continued to shrink smaller and smaller.

By the time they noticed something was wrong, they were no longer in their original form.
