The guardian of Crystals

Have you ever dream about being an immortal?
If you want to be one, ask June. She's been alive for how long? 3015 years, she's practically an immortal.

she's one of the guardians of the crystal, yes, I said one of, there's supposed to be three of them.

When you accept to be the guardian of the crystal, the power of crystal gives you infinite powers and life. It's not just a gift, it's a curse because the guardians have to see the people they care about left them, alone in the world.

If you couldn't bear the pain, there's always the option to give up your title of Guardian, then the Crystal will find their next owner and you died.

This story happened when one of the three Crystal is lost in the outside world, and was picked up by a random human?

June has to train him into a perfect guardian, to protect it from her greatest enemy Evelyn, who's a Guardian herself. Evelyn tries to have all three crystals, so she can become a goddess and change the entire world into what she want to.

Let me tell you, there's a reason why nothing good happens when accidentally pick up the magic crystal.
