Isogai
Summary
The elderly neighbor of the Furukawa family, Isogai is first referenced in The Scenery With a Carving, when Fuko accidentally uses her surname as a pseudonym. Although she does not officially appear until the Two Shadows arc, where she attends the school festival alongside Sanae to watch Nagisa's performance, her presence is felt earlier through mentions. In the ~After Story~ episode Disagreeing Hearts, a disguised Sanae adopts the alias Sanako Isogai while pretending to be Youhei's girlfriend. Later, in The Promised Founder's Festival, the real Isogai informs Tomoya that the local residents find Akio and Sanae’s antics at the store quite amusing.
