One day, Mami-chan sensed something chilling while walking through the city.

It was killing intent—sharp, raw, and unmistakable.

She turned and spotted a man in a suit, expressionless, standing in a crowded train.

Something was clenched tightly in his hand.

He hadn't hurt anyone.

Not yet.

But Mami could feel it—he was moments away from doing something terrible.

As an esper, Mami has a secret.

She can read minds.

It’s a power she keeps hidden from everyone—even her closest friends.

She knew that this man’s intent was deadly.

But without action, the law couldn’t touch him.

He hadn't done anything yet.

So she acted.

She casually walked up beside him, took a deep breath, and whispered a completely absurd joke:

“Hey… when you forget your wallet, you think saying ‘I also forgot my money’ makes it a lesser crime… right?”

The man blinked.

Then… pfft.

A tiny laugh escaped him.

“What the hell was that?”

“And… who even are you?”
