Fight Atlas republishes factual bout results, not source articles or photography. Belt markers appear only when championship status is confirmed by an official promotion source; unverified bouts are never inferred. The matched source name for this profile is Ryo Chonan.

Every verified opponent opens another full career
35 professional bout rows are displayed from the source record. 32 unique opponent identities have a stable source ID and an internal Fight Atlas route. Every opponent row has a verified identity link.
Source and correction standard
The complete professional history is retrieved from the established public fight-record source and cached for up to 24 hours. Current-roster status remains separate from historical career data and does not imply retirement.
