Doni

"Doni"

- Someone awaits at the Pivotal Ring.

Doni is the person that turned into a Life Reverberating Stone for Lyza and was processed into her whistle at one point. Doni is currently accompanying Team Riko.

Appearance
As a whistle, Doni's shape is similar to a common referee whistle. The whistle itself is decorated with the silhouettes of Eternal Fortunes, a glyph that represents "Netherworld" or "Abyss", and other embellishments. On the whistle's sides, there is a round protrusion featuring a key-hole surrounded by patterns.

In their previous life, Doni appears to have worn attire consisting of a skull-like mask with three keyholes reminiscent of their whistle form, and also appears to have been equipped with devices reminiscent of side-flashlights.

Personality
Doni seemed to be reserved as they choose to stop engaging in further communication apart from what they want to convey when Faputa transmitted their message to the group.

Early Life
At an unknown point in time, Doni met Lyza and formed a bond with her. Their bond later allowed Doni to become a life reverberating stone for Lyza’s White Whistle. Lyza took them with her on her last dive and for unknown reasons gave Doni to Reg alongside her notes. They were found by Ozen with other belongings of Lyza on a grave in the Garden of the Flowers of Resilience.

Orth Arc
When Hablog returned from his recent delving trip, he brought back Lyza’s whistle and belongings. Replicas of their whistle form were mass produced and distributed at the Resurrection festival dedicated to Lyza. Riko was later offered Doni by the Delver’s Guild as she is Lyza’s only relative, in which she accepts. Riko brought her mother’s white whistle with her when she makes her descent into the abyss with Reg.

Seeker Camp Arc
Riko gave Lyza’s White Whistle to Ozen temporarily in exchange for blue whistles to disguise herself and Reg. Ozen was seen lightly scratching and chipping Doni. When the duo departs for the 3rd Layer, Ozen gives Doni back to Riko.

Poison and Soul Liberation Arc
When Riko was laying down while Reg amputates her left arm, she held onto her mother’s White Whistle in her right hand as she endured the pain of the 4th Layer curse, Orb Piercer poison and Reg cutting into her arm. Nanachi was reminded of Bondrewd when they saw Lyza’s White Whistle.

Ido Front Arc
Riko investigates Lyza’s whistle while Bondrewd explains how Life Reverberating Stones are made, upon realizing Doni's existence.

Capital of the Unreturned
Riko asked Faputa if she could communicate with Lyza's whistle, similar to as she did with Prushka, upon which Doni transmitted their name to them and the message that someone is waiting for Reg at the Pivotal Ring.
