Inspiration for the Hiyomi Seven Gods?陽見七神元ネタ？The Nanatsuka burial mound group. Since it contains 「七」 and 「塚」, I thought this must be the model. (I visited during a social studies field trip in elementary school and only remember the name.) I was serious at the time and walked all the way there, but it was very far from the station, and all I remember is how tired I was. Well, since 「七の神」 is generally 「七福神」, 「塚」 probably has nothing to do with it ｗ
