Keiko
Keiko is Roxanne's friend who became a target for bullies at school. In the manga, Tamaki leads the harassment, pushing Keiko toward a desperate deal with The Rigani for money to pay them off—until Roxanne intervenes. That confrontation escalates into a full fight between The Rigani and Mantaro Muscle.
The anime handles her story differently. She appears alongside Roxanne and Trixie during the Tel Tel Boy match. In one memorable moment, Mantaro misinterprets Roxanne shouting her name as cheering for him. Later, when Mantaro faces Check Mate, Keiko notices that one mystery vote came from Rinko, though Rinko claims otherwise.
Throughout both versions, Keiko cheers for Team AHO with Roxanne and Tamaki. During the Poison Six Pack saga, she becomes the second hostage targeted. Dik-Dik Van-Dik and Wally Tusket manage to rescue her, with Seiuchin catching her as she falls.
