Saint

Saints (聖人) are incredibly powerful beings and the highest possible evolution of Humans and select Demi-Human races. They are able to fight at the level of a True Demon Lord and equivalent spiritual life-forms, wielding an absolutely terrifying level of strength.

Description
Only individuals that have endured countless hardships can reach this stage. The mental fortitude and will involved to reach this ultimate existence means their souls are strong enough to potentially acquire an Ultimate Skill.

Evolving into a Saint is a gradual process as it takes time for their material and spiritual bodies to fully merge, unlike with freshly awakened demon lords which can achieve this instantly through the Harvest Festival. However, there are a few ways to hasten this process temporarily, if not outright bypass it. For example, merging with an Elemental Lord or donning God Grade armor allows one to take on the properties of a spiritual life-form.

Another notable trait about Saints is they enjoy relatively long lifespans.
