Nisemono Seijo ga Honmono ni Katsugi Agerareru made Noso no Kateiニセモノ聖女が本物に担ぎ上げられるまでのその過程; The Fake Saint's Evolution Into a Genuine One

Seylan is a poor country girl with the power of healing. To help pay off the debts left by her good-for-nothing father, she is introduced to an easy job... a substitute for the saint! Dazzled by the large amount of money, she begins her pilgrimage before she knows it! However, her travel companions are a scheming priest, a pair of little twin magicians, and a muscle-brained knight commander, all incredibly handsome but incredibly eccentric characters. On top of that, for some reason, the saint is disliked by the people, and she has trouble wherever she goes...!? She was supposed to be a fake, but she's become the real thing!?
