Okay, something has me a bit baffled. Morisato Keiichi (along with the goddesses) lives on a property with a temple, but there's never an instance where people come to worship there. Considering that a monk had lived there, am I wrong to assume that the place was open to worshipers? Either way, why wouldn't it be? And is there some way that everyone would know that it's not functioning as a Buddhist temple, and not pay a visit?
Also, I'm not all that familiar with Buddhist temples. What's done in the main building? Worship/offerings/prayers? And there seems to be a much smaller building nearby. But I don't know what it is, and I'm not going to assume that it's something similar to what a Shinto shrine might have.
