This chapter is incredible in many ways that may not seem obvious to people from a Judeo-Christian background. I was wondering when I read the first chapter whether the worshipers understood what Elda is and whether they understood that she isn't an actual divine being in the traditional sense of divinity. She already admitted right away that she can't grant wishes or function like an actual god (from her perspective). However, in the context of a Japanese kami, her effective immortality is already more than enough. This chapter shows that the worshipers don't need a wish-granting god or a conceptually divine one. The fact that she's immortal and able to interact with them throughout their lives, unchanging and always familiar, makes her more of a god than the traditional divinities they can't see or touch.
It also doesn't hurt that she buys games, I guess.
