Anime with older characters

Can anyone suggest anime (not Hentai) with mostly over 18 characters?  Like these?

- Honey and Clover
- REC
- NHK
- Genshkin

Modeled does not = actual age. They are all over 100 years old, well over.

Anyway, Maison Ikkoku, macross, Tekkaman Blade

A few, basically just look at older shows before everyone was a pedo.
