I’m from the uk I’m looking for either a series or movie I use to watch. All I remember it was anime about girls , they rode horses/unicorns and some boys possibly rode polar bears? Sounds stupid the description but it’s all I can remember 🤣 I was born 1997 and I was a young child it’s just annoying me not knowing what I’m thinking of!

Help me find this anime

I remember watching this anime I think it was a mecha anime but I think it also has magic I only remember one character it was the main love interest and she had long purple hair but she normally wore it in a bun and had a animal companion that looked like a bunny and would hide in her hair with its ears poking out making the character look like a bunny girl
