The Prank War rages on with Danger Force's best pranker, ShoutOut, now on Team Rivalton, but Mika hopes to end the war before Ray's over-the-top retaliatory strike destroys Rivalton's economy forever.
When Archduke Fernando catches Bose with Mika in enemy territory, Mika must prove her Rivalton loyalty by pranking him. Bose remains Mika's friend but the prank traumatizes him, giving Ray impetus for an overkill strike-back plan that will permanently destroy Rivalton's economy. Mika seeks to end the Prank War forever.—statmanjeff
