The Saint's Class Change to an Elf Mage

You transmigrate.

Good news: You are a saintess revered by everyone.

Bad news: You have transmigrated into a dark reverse-harem story about confinement.

Good news: You possess powerful holy and healing abilities.

Bad news: Skin-to-skin contact can soothe other people's rampaging magic, so lots of people want to force you into, well, you know.

Good news: You transmigrated three days before becoming a saintess, and for now you're only one of the three candidates.

Bad news: The famously aloof and eccentric archmage, the sarcastic crown prince of the empire, and the bloodthirsty holy knight are all on their way to meet you.

What are you waiting for? Change careers now! There is no future in being a saintess. Set sail and become a spirit mage!

Are the four elemental spirits of earth, water, fire, and wind not appealing? Is overwhelming combat power and turning the tables on all those male leads who want to imprison you not appealing?

The strongest spirit mage on the continent: that's your future!

Theme: Stay focused and persevere, and you will reap the rewards.
