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.</p> <p>That said, this project is <strong>not</strong> 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.</p> <p><figure> <img class="my-0 rounded-md" loading="lazy" decoding="async" fetchpriority="low" alt="" src="https://ivonblog.com/en-us/posts/ecchi-fanservice-anime-list-specification/images/title.webp" onerror="this.onerror=null;this.src='https://ivonblog.com/images/cannotloadimage.avif'" width="512" height="288"></figure></p> <p>This page explains the project, the inclusion criteria, the data format, the source code, and possible future plans. <figure> <img class="my-0 rounded-md" loading="lazy" decoding="async" fetchpriority="low" alt="" src="https://ivonblog.com/en-us/posts/ecchi-fanservice-anime-list-specification/images/htxacgcc.webp" onerror="this.onerror=null;this.src='https://ivonblog.com/images/cannotloadimage.avif'" width="886" height="916"></figure> <figure> <img class="my-0 rounded-md" loading="lazy" decoding="async" fetchpriority="low" alt="" src="https://ivonblog.com/en-us/posts/ecchi-fanservice-anime-list-specification/images/t.webp" onerror="this.onerror=null;this.src='https://ivonblog.com/images/cannotloadimage.avif'" width="712" height="845"></figure></p> <h2 class="relative group">Scope <div id="scope" class="anchor"></div> <span class="absolute top-0 w-6 transition-opacity opacity-0 -start-6 not-prose group-hover:opacity-100 select-none"> <a class="text-primary-300 dark:text-neutral-700 !no-underline" href="#scope" aria-label="Anchor">#</a> </span> </h2> <p>This dataset mainly covers titles such as:</p> <ul> <li>mainstream Japanese anime</li> <li>non-hentai / non-porn anime</li> <li>ecchi anime and fanservice-heavy shows</li> <li>anime with visible nipple scenes</li> <li>bath scenes, changing scenes, swimsuit episodes, and other suggestive scenes</li> <li>TV, Blu-ray, OVA, and streaming versions when the differences are relevant</li> <li>titles where episode numbers, character names, and scene categories can be organized as metadata</li> </ul> <p>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.</p> <p>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.</p>
