Because of Anada, Angel was quite curious about the content related to Ritual Studies.
According to Anada, Ritual Studies was taught to her by Zithraide. So, when Angel left this morning, he asked Zithraide about it.
The result was unexpected; Zithraide outright said he didn't really understand Ritual Studies.
As for why Anada understood Ritual Studies, it was because of a book Zithraide gave her. The book was titled "Random Thoughts on the Handling of Abundant Grains," also known as the "Grain Book."
Zithraide had Anada work as a cook at an antique shop, which is why he gave her this book on handling grains to have a look at it at her leisure.
Unexpectedly, for Zithraide, this "Grain Book," which he had come across by chance, actually contained some content on Ritual Studies.
The information in the "Grain Book" wasn't anything advanced, including the rituals, which were all focused on grain processing and collectively termed as the "Pray-Eat Ritual."
