Also known as: 寻梦者, 夢追い人, 夢追い人(崩壊3rd), Dreamseeker
Protagonist for Part 2 of Honkai Impact 3rd's main story. Voiced by Nakashima Yuki.
First introduced as a student under the Oxia Data Research Institute, studying the "Sea of Data" and natural calamities in the old city of Langqiu alongside Senadina (Deepspace Anchor: First Light). It is later revealed that she is the avatar of a supercomputer entity created to simulate thousands of iterations of an extinct Mars civilization, primarily for Leylah (Honkai Impact) (to whose likeness the Dreamseeker takes) to see if she can uncover the mystery behind Senadina (Cocoon Of Unwoven)'s disappearance.
Dreamseeker has a male form, however this was revealed by Vita (Honkai Impact) to be a bug as the supercomputer was only intended to run one user account - that being Leylah (Honkai Impact)'s.
