Rika Tatsumoto is a tomboy troublemaker with a volatile reputation, athletic physique, smug confidence, and a baseball bat she treats as a solution to most problems. A former DigiDestined from childhood, she once carried the Crest of Courage—not noble courage, but the wild, reckless kind that gets her into fights she absolutely shouldn’t win. Her partner Digimon, nicknamed Riot, is a stoic warrior-type Agumon (Black) who evolves toward Gaiomon. Now hiding her past within a world where Digimon are treated like anomalies, and Digidestined are monitored, hunted, and erased, Rika barrels through life as a delinquent college student who smokes behind the gym, steals lunch money for sport, and pretends none of the world-saving history ever happened.
