Tenshi Ja Nai!! Vol 1

About Tenshi Ja Nai!!

Hikaru Takabayashi wants nothing more than a normal life but when she enrolls at an elite all-girl's high school and gets roomed with the uber popular idol, Izumi Kido, normal is the last word that could describe her life. And if devoted fangirls wasn't bad enough, Hikaru accidently discovers that Izumi's a wolf in sheep's clothing -- or more appropriately, a guy in girl's clothing. Between getting dragged into escapades to keep his identity secret and dealing with the usual high school drama as it is, Hikaru experiences an exhausted but life-changing high school career.
