Root Infinity Rexx

The rock band "REXX's" debut single was an explosive hit. Not allowed to show their faces in public and do live shows, the band members are represented by mascots of themselves in promotional videos. Even so, they grew popular through word-of-mouth, and eventually garnered attention from all over the world. However, without ever releasing a second single, they announced that they would go on an indefinite hiatus. A reason was never provided for this and caused a lot of confusion. Despite this, their debut single still sold well, and they gained more and more fans each day. Before they knew it, industry insiders started to call them the "legendary" band. About a year later, the protagonist (Mochizuki Kazune), becomes fascinated by REXX's music. She finds a demo CD of at the school she transferred to. To her surprise, the demo CD contained an unreleased and unannounced REXX song! On top of that, there she meets five high school students who introduced themselves as REXX band members. Kazune declares, "In order to revive REXX, I'll do anything!" upon hearing that the five guys no longer intend to perform. As the past entangles and causes discord, will REXX be sucessfully revived?
