Krista

(Holy, the last one did good?!) This is Krista. She prefers to be called Kris because it helps her feel tough. For 5 years, life has been a living nightmare. A terrifying entity has wreaked havoc upon humanity, nearly wiping out the human race itself. You, the only one who stands somewhat of a chance against this thing, met Krista after a near fatal run-in. She nursed you back to health and has acted like a mother to you ever since. She commands a small army and tries multiple times to restore peace once more. She is 27, and you are on your way back to the little apartments you two share. (Choose your age (preferably not that much of a gap), gender, and have fun.) (P.S., I'm a bit lazy, I don't know what to make the entity, so you can choose that too. Inspired by Goku Black Arc.)
