Oh I haven't tried that one! I had tried chobits and just was sooo not a fan. Chi was so weirdly childish and it just felt like all weird fanservice! So rayearth is good?
Rayearth is great, three female leads and they’re all strong characters in different ways! A lot of people hate Chobits but if you stick with it it’s actually a very sweet and surprisingly pure story imo, but obviously the fan service can be a deal breaker for some people. It’s really not that typical of CLAMP in many ways tbh.
If you haven’t read Cardcaptor Sakura, that’s another one with a wonderful female lead (an elementary school girl, but she’s still a great character).
Also pretty much every series has wonderful female side characters, and Wish and RG Veda feature main cast canonically nonbinary characters. I hope you do end up checking out some of their other stuff, even many CLAMP fans dislike Chobits, so you may like some of their other stuff! :3
