Kunado’s Locus is one of the three hidden areas in Enkanomiya. Upon descending into Byakuyakoku, Kunado’s Locus will be hidden from view on the map, even after lighting up the entire region. To make it visible in the World Map, you must first accept the World Quest called Erebos’ Secret, which will prompt you to take on the Three Great Martial Trials.
You can do so by heading to the upper right corner of the altar in The Serpent’s Heart during Evernight after completing the From Dusk to Dawn in Byakuyakoku questline. You’ll find the afterimage named ???, who will reveal herself to be Eboshi. Speak to her to unlock Kunado’s Locus.
Getting to Kunado’s Locus
Start by heading northeast of the Teleport Waypoint south of The Serpent’s Heart. Jump down to find a bright clearing with water and a school of Ghostfish floating above it. Use a Geo Construct, Wind Current, or use the nearby rocks and a tall character to jump into the Ghostfish.
Once you’re at the center of the school of Ghostfish, don’t click on anything and let the fish lift you up and transport you to Kunado’s Locus. If you fall from the Ghostfish, try again and consider jumping from a higher platform so that you land directly into the center.
When you make it to Kunado’s Locus, don’t forget to unlock the Teleport Waypoint in the area for easy transport in the future.
