Live-On is packed full of crazy VTubers, but with Awayuki Kokorone's popularity skyrocketing after her legendary streaming accident, she finally gets the chance to collaborate with her hero, the company's only first-gen member: Hareru Asagiri. And it's not just any collab—Hareru, who normally never agrees to take center stage, is holding a solo concert, and she wants Awayuki to sing a surprise duet with her at the end!

Will her sanity hold out until the concert?
