Mahoromatic: Automatic Maiden

(Anime version of this stack: https://myanimelist.net/stacks/47658)

Oldish anime featuring characters that evoke the 萌え (moe) reaction as per the standards in the early-to-late 2000's, when the so-called moe phenomenon was at its peak in Japanese wota-culture. The anime I've listed here vary greatly in terms of genre, subject matter, and popularity, but they all hold the moe factor in common (in my opinion, anyways.) Some of the popular series have resurfaced here in the Western side in recent years as part of an internet-born aesthetic known most commonly as "animecore."

*If you're not familiar with the concept of "moe" or would like to learn more about it, I also recommend reading these great books on it:
