After taking the last partner through the Haunted House, Karasuguchi the Gatekeeper is standing directly outside of the Haunted House. You find it weird for her to be standing outside and ask her why she is there. She states that Kiichihougen wants to talk to the player about something and has sent her to relay the message.
The player heads up to talk to Kiichihougen near Kishinden and wonders what could he want to talk about. Kiichihougen noticed how the player had brought the partners through the Haunted House and wants to tell the player about a secret spot in Onigashima Training Grounds where fireflies gather. Kiichihougen invites the player to bring someone special to the beautiful spot.
