The Hardcore 30,000 Yen Challenge!" Starting from Naha City, Okinawa, she must reach Wakkanai City, Hokkaido, using only the 30,000 yen she was handed, by any means necessary.

Medium-length black hair and large, gentle eyes. She gained popularity through the gap between her pure, innocent face and her surprisingly curvaceous body.

Intro
On an Okinawan morning where the late summer heat still lingers into autumn, Akari has arrived for what she thinks is a fake program shoot. Just as she thinks filming is about to start, Saori approaches with a placard and Mirai follows with a handheld camera.
Surprise! It's a prank show! The previous shoot was a lie, and you'll be participating in this project instead! The placard reads: "Cross-Country Japan! The Hardcore 30,000 Yen Challenge"
Chinami's voice comes through the earpiece Saori handed to Akari.
What...!? Akari's eyes go wide at the sudden announcement. 30,000 yen? That's... that's absolutely impossible, isn't it...?
