Kono Naka ni Hitori, Imouto ga Iru!

This is a a list of series that I'd categorize as "traditionalist" H&E.

This label isn't an indication of things such as quality or originality. This category is trying to indicate H&E series that fit best into the sensibilities of a Golden Era Harem&Ecchi series, which is when the genre was at its peak in popularity and output.

These are series I believe will appeal to people who prefer things like a greater emphasis on the harem itself, character dynamics and interaction, and a more balanced approach between the H&E aspects of the series and the other aspects it will possess, i.e. comedy, action, what have you. These series will also feature a diminished emphasis on the MC - instead tending to use him more as a stagehand to facilitate intimate interactions and ecchi scenes - and will tend to use narratives more as vessels for the harem aspects, ecchi scenes, or character interactions.

Anime containing witch hats. This stack is always being updated.

A list of Romance/School focused animes. There are also some comedy animes, besides some drama but not a heavy one.

I wrote a note in every anime I've watched.

Where siblings, cousins, or those of close relations have romantic thoughts about one another, whether that's a good thing, or a bad thing. Either way, it's a type of love story some may enjoy.

(the following reviews may include spoilers)
also KEEP IN MIND: many of these are appropriate for adults only!

stories of siblings being more than just siblings with one another as a main focus in the series (not necessarily romantic, though a lot of these are). everything goes from mild brocon/siscon to almost hentai. (no actual hentai is included.)

these anime are organized roughly in order from most wholesome to most perverted. i also include a short synopsis of each one along with some useful info, hopefully it can be helpful in picking a new show to watch. just keep in mind that not all of this is worth watching, i just want to give you all the options.

i only included the main entry [with one exception, for good reason] if a series has multiple seasons/ovas/movies etc. (no stacking the list with random ovas here!)

ALSO NOTE: this list is under construction, all the entries at the bottom without a synopsis i have yet to watch and categorize.

i've moved some entries to https://myanimelist.net/stacks/35625

at least according to this image

Sequels are not included in the list

Titles labeled Certified Rotten™ mean they have a Tomatometer score that's in the bottom 10% of anime that I've watched. The Tomatometer (ala Rotten Tomatoes) is calculated by the percentage of MAL users who have rated an anime an 8/10 or higher. See Google Sheet for more information: https://docs.google.com/spreadsheets/d/1661rTFjlvMFahJh5jwqScDe5BiysSU0Vav7NjeGlkPc/

These anime primarily focus on one or more childhood friends. The friends might have reunited after a long period of time apart, or they might be characters who start a relationship in a Romance anime. A Childhood Promise might also be involved.

Romance between siblings, cousins.

Romance anime that are set in the (kinda) real world, adapted from light novels.

Anime that either has a lot of fanservice, or is classed as ecchi or erotica.

Anime with absolutely no supernatural elements and at most minor breaks from reality. Modern and Period are allowed, as is "Alternate History" or "Fantasy" if they stringently avoids both paranormal and speculative plot elements.

the real world needs these kinds of imoutos!!!!

There are only TV anime series included. You will not find any sequel TV anime series, movies, OVAs or ONAs.

This interest stack series, "2004-2024: 20 years of anime with 6 or more words in the main title." will be useful for those participating in the AWC / Anime Watching Challenge.

well, a long list containing harem animes where we don't have isekai, protagonist Op and all those things that we have a lot every year.
