The Saint's Magic Power is Omnipotent (Light Novel) Vol. 5

Now that Sei has performed multiple miracles in the capital and beyond, her reputation is on the rise, as are her business ventures. Unfortunately, not everyone harbors entirely noble intentions for the Saint. Some would use her for their own ends. That's why Sei's friends and benefactors want to help her start her own company, as well as to secure her official place in high society--before someone tries to claim everything she's made, and everything she is, for themselves.
