Chu-Bra

"A wonderful day begins with wonderful underwear!"

—Nayu

Nayu Hayama, a middle school student, surprises everyone when she trips at the school entrance ceremony, and, thanks to a well-placed Panty Shot, is revealed to be wearing lacy underwear unfitting for someone her age. It's revealed that Nayu's older brother Keigo is an underwear designer, and Nayu herself is a a fan of all things undergarments. So she decides to help her fellow classmates be more knowledgable by creating an Underwear Club in school, and recruits two best friends, Yako Jinguuji and Haruka Shiraishi, in with her. Nayu's indefatigable enthusiasm sweeps up a worldly girl (Kiyono Amahara), a busty home-room teacher (Tamaki Mizuno-sensei) and a flustered boy (Hiroki Komachi).

Based on the manga of the same name, this Twelve-Episode Anime aired in the winter of 2010.

Tropes used in Chu-Bra include:

• Adaptation Dye Job: Everyone had the same brown hair in the original source, but they were given varying shades in the anime. Only Nayu remains largely unchanged.
• Adult Child: Mizuno-sensei, the Underwear Club's sponsor and assistant homeroom teacher.
• All Men Are Perverts: Only Komachi and Nayu's stepbrother are portrayed sympathetically, but the population of the school is largely thinking with their libidos.
  • Justified Trope: At that age... Trust me on this.
• Beach Episode / Hot Springs Episode
• Cerebus Syndrome: And HOW.what begins as a risqué loliconesque fanservice comedy series evolves (at least in the manga) on an exploration on budding sexuality and an analysis on sexualization. It also points on how Nayu cannot connect the actual meaning of titilating underwear with her own emerging romantic feelings due to having spent all of her life surrounded by lingerie in a neutral context.
• Character Development: A pretty surprising example.
• Chewing the Scenery: The Acting Club is over the top in all situations.

• Hey, It's That Voice!: Nayu is voiced by Minori Chihara. That's right, Yuki starts her own underwear club!
  • Kiyono is Mio Akiyama, while Yako is Tsumugi Kotobuki.
• Innocent Innuendo: The "unhooking the bra of a mannequin" trick is used twice, first to make us think that Komachi is unhooking Nayu, the second time is Haruka and Nayu with each other.
• Hexagonal Speech Balloon: Heavy usage of them in episode six.
• Huge Schoolgirl: Haruka, who's easily the bustiest of the main trio.
• Imagine Spotting: When looking at a catalog of imported underwear, Yako imagines Haruka in a pair of them. Which Haruka knows she's doing.

• Love Letter Lunacy: Happens in episode seven. Turns out the secret admirer put it in the wrong locker.
• Meganekko: Nayu
• Male Gaze: Rotated ninety degrees: Nayu zeroing in on Haruka's breasts the first time they introduce themselves. An HUD even pops up behind her eyes, analyzing the other girl's bust.
• Mistaken for Gay: At the end of the first episode, though it's not like Nayu was in a better position before that.

• One Degree of Separation: Nayu's stepbrother knew her teacher back in high school, and both of them are still living in the area.

• Serious Business: According to Nayu, underwear is.
• Sleep Cute: The end of episode five.
  • Also the car scene near the end of episode 8.
