R-15 was a 12-episode ecchi/ harem comedy TV anime that originally aired in Japan from July 10 to September 25 of 2011 and was animated by AIC. The series was based on the light novel series written by Hiroyuki Fushimi from July 2009 to August 2012. The series was aired in an edited format for TV broadcast and released unedited for its video release. It is available for legal streaming via Crunchyroll.
Inspiration Academy Private High School is a school for gifted high school geniuses that is attended by Taketo Akutagawa, who is known to write erotic novels. Considered a pervert by many among his class, Taketo aims to be the top student of the school and attempts to befriend several students among the school's female student body.
R-15 is yet another ecchi title with a premise that is a thinly-veiled excuse to show off perverted content involving our male lead and several girls he gets acquainted with at Inspiration Academy throughout the show's run.
The characters are all two-dimensional archetypes you would find out of high-school-themed and harem titles, many of whom hardly getting much in the way of fleshing out. The plot is mostly centered on Taketo becoming acquainted with a different archetypal girl, earning their trust and using whatever situation each girl is in as inspiration for his erotic novels. Also, perverted content is mostly the norm in this turd with lewd fantasies, revealing attire, undressed moments, innuendo gags, panty shots and compromising situations being shown at many points throughout this series.
Of particular note with this show is the way it censored its content for its TV broadcast. Beams of light are used to cover up any questionable content visually shown. However, there are points where this censorship gets quite overboard and even inconsistent as there are points undressed states like panty and lingerie shots are either censored or not at all, even if said shots weren't gratuitous or bordering on showing outright nudity.
