Lyza/Relationships

Riko
Though Lyza left Riko as baby in Orth, it is clear that she cares about her very much, as she was heartbroken when Riko was stillborn and told Jiruo to keep her identity secret in order to not lead trouble towards her.

Ozen
Before becoming a White Whistle Delver herself, Lyza studied under Ozen as an apprentice. They became very close friends, and Ozen is very fond of Lyza. When Lyza introduced her husband, it greatly stunned Ozen at first and she appeared dismayed and unaccepting of the decision.

Reg
On multiple occasions, Reg receives flashbacks involving Lyza hinting at a connection between the two. While Reg is doing chores for Nanachi, he hears his voice from a memory saying "I'll be going now... Lyza..." and it is transported to a memory of him in front of the Blaze Reap tomb at the Garden of the Flowers of Resilience. After the release of Mitty, during the 2 hour sleep after using the Incinerator he sees a memory of him crying while looking at Lyza's back, Lyza comforts Reg and hands him a bowl of Lyza’s Cooking, she then says "Once you're done eating, we're heading out". During the battle in Ido Front with Bondrewd, Reg wakes up after overcharging and claims to have been controlled by someone among many people who come to his mind, among them Lyza appears implying there may be a connection between them. Lastly, as Faputa is fighting Reg, Faputa's memories show that Reg was holding onto the Blaze Reap.

Torka
At some point in time, Lyza married Torka. Not much is known about their relationship or how they met each other.

Jiruo
In his childhood, Jiruo was the apprentice of Lyza. Though he was only a Red Whistle Delver at the time, before she made her last dive, Lyza entrusted him with watching over Riko and protecting her identity as a White Whistle Delver's child.

Human-looking silhouette
Lyza describes in her notes an encounter with a Human-looking silhouette somewhere near the 7th layer. While the silhouette was watching Lyza, she took notice as well and kept an eye on them. When Lyza tried to call out to them, they escaped jumping.
