Sylvia Lyyneheym holds a dual position as both the Student Council President and the top-ranked Striker of Gaen Wissel Girls' Academy, while simultaneously commanding the global stage as an elite idol under the fearsome moniker 'Witch of the War Cadence.' Her extraordinary ability to manipulate phenomena through song places her among the most formidable fighters in the series, having claimed runner-up honors at the prestigious Lindvolus tournament.
