Ecchi Fanservice Anime With Nipple Scenes Dataset is Now Open-sourced

I open-sourced a structured JSON dataset for cataloging ecchi and fanservice anime, especially mainstream non-hentai titles with visible nipple scenes.

What is this?
#

This is a dataset for tracking ecchi and fanservice scenes in anime, with a particular focus on whether a title contains visible nipple exposure.

By “ecchi” or “fanservice,” I mean mainstream anime that includes sexually suggestive scenes: bath scenes, changing scenes, swimsuit episodes, exposed breasts, butt shots, and similar material made for the viewer’s gaze. Some titles are censored during TV broadcast with steam, light beams, mysterious shadows, or other holy censorship techniques, and later get less censored versions on Blu-ray, DVD, or certain streaming releases.

That said, this project is not a hentai or porn database. The focus is on commercial Japanese anime that still belongs to the mainstream / non-hentai side of anime culture. In other words: this is the cursed middle ground where TV anime, BD upgrades, and horny metadata meet.

This page explains the project, the inclusion criteria, the data format, the source code, and possible future plans.

Scope
#

This dataset mainly covers titles such as:

mainstream Japanese anime
non-hentai / non-porn anime
ecchi anime and fanservice-heavy shows
anime with visible nipple scenes
bath scenes, changing scenes, swimsuit episodes, and other suggestive scenes
TV, Blu-ray, OVA, and streaming versions when the differences are relevant
titles where episode numbers, character names, and scene categories can be organized as metadata

This list began as a private project on my personal website around November 2021. I slowly collected information from multiple sources and organized it into tables, including anime titles, episode numbers, character names, and scene notes.

I have checked more than 200 anime titles while working on this project, but this kind of information is scattered across old blogs, forums, wikis, imageboards, personal notes, and random comments from people who somehow remember the exact episode where the censorship disappeared. There are still missing entries and errors.

Ubunchu! Learn Linux Through Manga and Understand Free Software Community Culture

The world’s first! Ubuntu school romantic comedy manga.

Ubunchu!, whose Chinese translation calls it Wubangchu, is a manga drawn by Japanese manga artist 瀬尾浩史. It was once serialized in Ubuntu Magazine Japan and has now ended.

The manga introduces the Ubuntu system in a light and humorous tone. Whether you are a newbie or an old hand, you can experience the fun of Linux from it.

It does not use the technique of operating system anthropomorphism (OS-tan). Instead, it truly acts out how Linux is used in daily life.

This manga was published in 2009. The system that appears in the manga is roughly from the Ubuntu 9.04 era, and later the heroine spends an entire day and night upgrading to Ubuntu 9.10. Perhaps because of trademark issues, the manga uniformly calls Ubuntu Ubunchu?

Although it is old, the things it talks about are still applicable today! For example, GNOME still occasionally fights with X Server and crashes. ( ~~Just cut X11 support directly and switch to Wayland, then you do not have to worry about this problem~~ )

Compared with Linux comics drawn by Daniel Stori and xkcd, Ubunchu! does not talk about too many technical things. It mainly talks about Linux and free software community culture, as well as the real-world difficulties encountered when promoting Linux to Windows users.

如月あかね: President of the System Administration Club. A fanatical Unix believer who prefers browsing the internet from the command line and did not know desktop graphical systems existed until high school.

御堂マサト: A Windows user, vice president of the System Administration Club, and Kisaragi’s archenemy.

椎名里沙: A Macintosh user and natural airhead, but also the first person to promote Ubuntu to the club members.

篠崎あきは: President of the Computer Science Club, opposed to free software solutions.

3. Episode Summaries of Ubunchu!
#

Although this manga series can be freely reposted, for length reasons I only include the covers.

Episode 1: Ubunchu Appears!

うぶんちゅがやって来た！

Linux CLI hardcore faction vs. Windows user vs. Mac user.

Unexpectedly, it is the Mac user who first wants everyone to try Ubuntu? By the end, even the Linux CLI hardcore faction is shocked by Ubuntu’s friendly interface.

As long as you have Wine, you can even play Windows bishoujo games!

Episode 2: CLI and the Little Sprites

ＣＵＩとコビトとお姉さま

Introduces Linux command-line concepts.

In this episode, Shiina Risa treats Linux commands as little sprites working inside the computer, and the Linux desktop environment GNOME happens to mean a small sprite in English.
