Eita Chinami is a high-school delinquent who wants to become the most badass guy in school to win the chance to confess his love to school idol Yuika Kitano. He tries to achieve that by beating the crap out of every tough guy in and out of school. However, when he catches a cold and ends up taking the wrong pills, he wakes up the next day... as a girl. And an incredibly cute one, at that.Now the only cure to his/her little predicament is to drink the pills again. The catch — (s)he is 300 million yen short of a jar of it! With his/her metrosexual best friend Keisuke Oguri, Chinami vows to return into the true man (s)he always was... by having to take up an idol job — and to his/her surprise, Yuika is also an aspiring idol.Idol Pretender is a Seinen manga series written and illustrated by Hiroki Haruse.
Idol Pretender provides examples of the following tropes:
Bound and Gagged: Chinami and Yuika both get tied up after they get caught by a stalker.
Can't Hold Her Liquor: Yuika tends to get aggressive when drunk. And ANY amount of liquor seems to do the trick.
Clingy Jealous Girl: Chinami shows this (and (s)he couldn't explain why) whenever it is something related to Oguri.
Chickification: Early on Chinami establishes her/himself as a bit of a badass with some pretty powerful kicks to people/equipment. Then Chinami failing to defend him/herself from the stalker in chapter 4. In his/her defense, he did have his legs tied up, but he also managed to snap the ropes around his torso without much apparent effort. As the series progresses, Chinami continuous to become more dependent on Oguri to defend her.
Chivalrous Pervert: Oguri, through and through. He may be shameless enough to strip in the middle of a crowd and even doesn't mind getting too close with female Chinami for comfort, but he's always ready to defend his/her honor.
Gender Reveal: So far, this has happened thrice — in Chapter 3, where Aoi revealed to Chinami that she is actually a he, in Chapter 7, when Chinami and Oguri finds out that Rintarou is a she, at at the end of Chapter 13, when Yuika overhears Chinami summarizing his/her problems to him/herself.
Good Angel, Bad Angel: Yuika has them in chapter 11 as she questions whether she should look up Chinami's skirt while she's unconscious to confirm his/her gender.
Literal-Minded: Oguri warns Chinami not to punch anybody after he debuts as an idol, so when an armed thug breaks onto the stage and takes Yuika hostage, Chinami takes him out by kicking him.
Love Dodecahedron: Chinami has a crush on Yuika, who eventually declares her love for his/her female persona. Also, Chinami is Tsundere around Oguri (to the point that (s)he wonders whether (s)he's actually going gay for him), and both of them have crossdressers crushing on them, male Aoi Subaru and female Takizawa Rintarou, respectively.
Man, I Feel Like a Woman : One of the first things Chinami does post-gender-flip is to grab his/her breasts and see how it feels... much to his/her dismay, (s)he actually gets aroused.
Meaningful Name: Godlike Beauty DX. "DX" is an emoticon that could mean either horror, disgust, sadness or great dismay — the very spectrum of emotions Chinami felt when he woke up as a girl for the first time.
No Romantic Resolution: We never learn precisely what Oguri told Chinami or Rin, leaving the question of the final romantic pairs unexplained.
Phlebotinum Pills: The magic pills Chinami accidently takes at the beginning, Godlike Beauty DX.
Pinball Protagonist: Chinami basically just goes with whatever zany antics the other characters lead him into at a given moment.
Second Law of Gender Bending: Played with. After finding out that Yuika is in love with his/her female form, Chinami starts thinking that it might be better to just stay as a girl... right before (s)he chews him/herself off for thinking that.
Seinen: The manga is serialized in Champion RED Ichigo magazine.
