No harem, ecchi, bl or gl
*They are tagged as romance genre in general, the degree of romance content varies and some blooms in sequels which will require patience.
!After completing the anime it's recommended checking out the sequels, movies and/or source materials, if they have those, to confirm couples getting together and/or for further developments.
*Please do specified research before giving your time to watch.
I generally put similar ones side by side.

This stack is for modern or relatively modern anime that are done in a nostalgic-classic style. I mean, old character designs and aesthetics, themes, tropes or formula, direct quotes homage for old animes, etc. As an option, new sequels (spin-offs) to old shows or their complete reboots for a modern audience. Or if their first adaptation at all can come true just in our times (Or if they were adapted at all for the first time only in our time).

sometimes there may be several cats, but i only choose the first appearance or the pic that i think is beautiful more

nekomimi and accessories count, it's fun and there's more variety that way

An assorted stack of anime series involving alien characters on Earth or set in alien planets.

Anime that come out in 2024, for which I'm hyped for and anime that sound interesting, with the date they premiere on.
