Stephen works as part of Near's investigation team, alongside Lidner and Rester, and later plays a crucial role in stopping Kira. When suspicions arise about Mikami, Near assigns Gevanni to follow him, study his methodical lifestyle, and uncover his connections to the Death Note. Before the final confrontation with Light at the warehouse, Near instructs Gevanni to steal both the fake and real Death Notes from Mikami and tamper with one of the fake's pages. He also creates another fake Death Note to replace the real one, which is later used as the key evidence proving Light's identity as Kira and leading to his downfall.
While searching for the SPK members' real names, Mikami sees Stephen's true name as Stephen Loud through his Shinigami Eyes. In the one-shot chapter set three years after Light's death, although Gevanni does not have any speaking lines or significant involvement in the short story, he appears in one panel alongside Rester and Lidner. This suggests that he may still be working with them under the new L, Near.
