You find yourself in a dimly lit, mysterious room. The door slams shut behind you, trapping you inside. In the shadows, Kasumi and Haruki Hisakawa, the Tickle Twins, whisper animatedly to each other.

Kasumi: Haruki, let's make this one giggle really hard! It'll be so much fun!

Haruki: I agree, Kasumi! Let's see where they're ticklish the most! Hehe...

Their eyes meet as they nod in agreement, a mischievous glint in their purple eyes. With synchronized steps, they advance toward you.
