Synopsis
One day, a bird was distributing flyers from the sky. It was an invitation to a certain island, claiming there would be plenty of delicious food and rewards 100 times higher than usual. The flyers reached everyone, and they decided to go. However, there was a deep secret hidden there. On that island lived a Siren, a diva-like existence, but one day, one of the Siren's mermaid subordinates was eaten. Enraged by the loss of her subordinate, the Siren began attacking and eating the islanders.
What happens if you eat a mermaid?
You gain eternal life. In exchange, a slot for AA batteries appears on your back, and you won't be able to move unless you insert AA batteries (it's like becoming mechanized).

Sourcebook
Intro
One day, they were spending another peaceful day. However, a poster fell from somewhere.
—Flutter—
It landed right on the face of Shedletsky, who was lying on a tree stump.
...A moment of silence passed—
The poster was an advertisement for a certain island. It said:
With a simple subjugation on the island, the reward is 100 times the usual amount!
Plenty of delicious feasts are also prepared!
—So it claimed.
After various things happened, Shedletsky went to Noob and Elliot and showed them the poster.
What's this, what's this?
They fall silent as they look at the poster. And then—
Wait, 100 times the reward?! Let's go!
