The kind of power feedback that is as if a shrine appeared out of thin air also comes from the Child Day Bow.
"This bow from Wakahirume no Mikoto seems to have deepened the connection between me and Hotaru. Although I don't quite understand why yet, it seems to be beneficial to me on Hotaru's side as well," Kamiyagawa thought to himself.

Kamiyagawa had Onizuka take Abe no Seimei's notes back to Kyojin Shrine to study, and then provide him with a copy later.
The notes record Abe no Seimei's Kikyo Spell Method, mostly related to talismans.
