12 Episodes


Alternate Titles

Size B Type Ecchi*


Romance; Comedy; Ecchi*


Beautiful, popular Yamada has a dream, and her dream is a big one, for her dream is to have sex with a hundred different guys. Large: yes; achievable: not when she’s struggling to find someone who’ll share in her first kiss. She has her desires set on devouring a virgin boy for her first to avoid any accusations about a lack of experience on her part. Luck strikes when she falls (literally!) into the life of completely average and forgettable Kosuda in a bookshop. Eventually determining that he will do nicely, she now has to find the lucky lad and let him know. If only she could remember what he looked like…

Content Advisory

This is not a comprehensive list of every individual use of strong content, merely a guide to show you how extreme it gets and how strong it tends to be. Also, the tags I’ve given each segment (e.g. Very Strong Language) is based on my own system and does not necessarily reflect the tags the BBFC (or other national equivalent) use. According to my system, the ‘Mild’, ‘Moderate’, ‘Strong’ and ‘Very Strong’ adjectives are based on strength, not on volume. Now, obviously, the strength of any type of content is subjective; what I consider strong might just be a relaxing weekend for you. Hence, I have added an explanation for my decision to allow you to make your own informed decision.

Please also note that the ‘colourful’ language I am referring to here is based on sentai FILMWORKS’ English Dub. The Japanese Dub may (and probably does) differ.

Strong Sex References

Seeing as this a series about the protagonist trying to lose her virginity, it will come as no surprise that the references are strong. From premature ejaculation to masturbation to everything inbetween – this show bares all. Although, it doesn’t go too fetishy!

Moderate Sexualised Nudity

In most episodes, the nudity is censored with steam or other means, suppressing any nipple detail. The last episode, though, depicts a few scenes of nipple detail.


No, this is not a spoiler to put this category here, for there is porn shown in at least one episode. Shock-horror, the porn shows a sex scene. Other scenes also show sex, but it’s fairly infrequent and undetailed.

One scene shows a character masturbating, however, the camera only shows him from behind. As such, nothing is seen (only heard!).

Strong Language

The outtakes special feature contains uses of ‘fuck’ and ‘shit’, and the main show may contain similar language.

Reasons to Watch

This is the difficult part. I don’t want you to see this entry as an oversized ‘DON’T WATCH THIS’ post. Equally, I don’t want to influence your opinion with a biased review – there’s a reason this website is called ‘Anime Insights’ and not ‘Anime Reviews’! In this section, I’m going to try to convey to you some of the reasons (in no particular order) that I’ve seen this show’s fans give for enjoying it!

A well-received sex comedy that often touches on the peer pressure surrounding sex

Not too explicit, despite everything, but not badly censored, either. Therefore, it may appeal to viewers who want the sex comedy without the discomfort of sitting through endless sex scenes.

An English dub that does take a few liberties, yet still manages to have been received better than the original by many critics. This means that its dub is a great starting place for anime newcomers and even sub-lovers who are trying to get into dubs.

Barrier of Entry

Some viewers may be unhappy with the very slow progress the series’ main relationship makes.

Viewers may find the incomplete ending unsatisfactory.

Hardcopy Notes

Special features are present on both the Blu-Ray and DVD, including Outtakes.

FUNimation’s release features both Blu-Ray in Region A | B and DVD in Region 1 | 4. This means that Blu-Ray viewers in the UK (and Australia) can watch freely on a standard Blu-Ray player. However, DVD viewers will have to explore alternative ways of watching it (e.g. Multi-Region DVD Players and the like). Although, it should be noted that the DVD restriction does not apply to viewers in Australia.


In the English Dubbed porno that the two watch towards the end of the series, you can hear the female pornstar (played by Jamie Marchi, who also served as a writer on the show) say ‘you’re making me hotter, Potter’. This line refers to the male pornstar who is played by Brandon Potter.

For Your Anime Dictionary

*Ecchi is a genre of anime that is fanservice heavy. It can go as far as to show softcore pornography, but any further and it hits ‘Hentai’ territory. Both ‘Ecchi’ and ‘Hentai’ can also mean ‘Pervert’ and, occasionally, ‘Ecchi’ is spelt with a simple ‘H’ (short for ‘Hentai’). I suppose it embodies the idea that Ecchi is just a small portion/the beginning of Hentai. Either way, the title refers to Yamada’s bust size (B) and the fact that she is a pervert (i.e. B Gata H Kei).
