Protagonist for Part 2 of Honkai Impact 3rd's main story for Chapters 1-3.
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 he is a mistakenly created second user account in the Mars supercomputer intended to simulate thousands of iterations of an extinct Mars civilization, as the supercomputer was only intended to run one user account - that being Leylah (Honkai Impact)'s, to which the proper user account takes after her likeness.
