A shorter arc for Seita-kun than I expected, but a similar effect that Goro and Kogane's kindness has an effect on him. I bet we do see him again at a point where he can accumulate a lot of positive karma. I also appreciate the slow burn peeling back of the layers of Mogami-sama's plan. Whoever becomes the new god of the land is gonna have to work hard to reach Mogami-sama's level.
Prayers and offerings are the spiritual nourishment kami need to maintain their power. Of course an offering is tastier than something they buy themselves. While this might just be a cover story, Mogami-sama says in chapter 38 that she works in the human world because she wants to buy good booze beyond what her offerings can afford. So, desire for good food and booze and desire for offerings are two distinct things that are better when they overlap.
Thanks as always to sarusa and thumper. Enjoy the bourbon and BBQ, sarusa.
