IV (pronounced as "Eve"/イヴ, Ivu), is the manager and DJ of the music and dance idol unit Full Throttle4, and a third year high school student.

Even though he's the behind-the-scenes leader who formed and leads the group, IV prefers to work offstage to help out the other four members. He's rarely seen other than when he's performing as DJ in live shows.

An animated movie project announced to commemorate HoneyWorks' 10th anniversary.<br></br>

The movie will center around the story behind male idol unit LIPxLIP, and its members Yujiro and Aizo.

Hiyori left her hometown to pursue her passion, track and field, by enrolling in Tokyo's Sakuragaoka High School. Looking for a part-time job in Tokyo, she ended up working as an apprentice manager for her classmates (and LIP×LIP members) Yuujirou Someya and Aizou Shibasaki.
