OK,1st off,Ami's seiyuu is Hisakawa Aya.Her other well-known role is Skuld of *Ah!Megami-Sama*.She's also Kon Rei of *Bakuten Shoot Beyblade*,and Chloe on *Noir* as well.And,another well-known Aya role is Mano Yohko of *Mamono Hunter (Devil Hunter) Yohko*,where she also sings most of the series's music.
The ring Mamoru gives Usagi is not an *engagement* ring,but actually a *promise* ring.In Japan,when you give someone a promise ring,you are promising to stay with them forever,and alwayz be there to protect them.There is no requirement of marrying the person you give a promise ring to,like there is of such when you give someone an engagement ring in the U.S.,tho alot of pplz still do marry that person.
As for marriage between Usagi and Mamoru,anyone who has watched the *PGSM: Special Act*,even if they have not read the mangas,is aware that Usagi & Mamoru are now married.So,much happiness to The Chiba Family.
Also,if you watched the above,you know that each Inner Senshi girl went on to become what she alwayz dreamed of....Ami--a doctor,Mako--a chef & etc.
Again,if you haven't seen the *PGSM* series,you can d/l eps. @
