Please name her! (Anime-Tamae! new character) (Patreon)

Today I was drawing & painting a new character for my sexy Youkai comic "Anime-Tamae!"(http://animetamae.com/en/)

As you see above, she is first Christian character in the comic!

Oh, and she is not an ordinary Nun... I imagine there are many pure nun characters in the Anime-Tamae world... but she is not.

Like Tensei Maidens, she uses power of otherworldly beings... but it is not divine energy. She uses demonic ones. To fight against evil Youkai and protect innocent people, she opens her body for demonic possession...!

Well, then, would you give a name for her?

I can think some names (inspired from books or Warhammer40k like games), but I hope a name sounds cool for oversea people. Probably it should based on Chiristian culture, Italian ( Vatican?) or has taste of vice, sin. (But not too demonic...?)
And perhaps her final name will have a title "Sister" (so she will be called "Sister [name]" in the comic)

I made many design sketches for her, like this!

I'm still thinking about her final design.

A Pink skimpy dress is not bad... (but too much "Bimbo" tasted?)

I love darker skin... but for this character, tanned skin is better...?

Hair style is also hard to decide...

Though it is not a "vote", I'm glad if you give me comments about her design! (Numbers may be useful when you mention those candidates above)

Thank you for your support! :D
