Sasara Kusugawa serves as the disciplined vice-president of Kaiyou High School’s student council, eventually rising to the presidency. Her aloof exterior and stern approach mask a history of limited personal connections, with Ma-ryan standing as her sole confidant before Takaaki Kouno enters her life. As Ma-ryan’s graduation strains their bond, Sasara grows closer to Takaaki after he volunteers to support the council, their partnership solidifying when he assumes the treasurer role. Through shared responsibilities, trust blossoms, softening Sasara’s guarded demeanor and kindling unspoken romantic feelings that challenge her reserved disposition.

Sasara’s striking appearance features long, middle-parted blonde hair secured by a black headband, with spiky bangs and wavy side strands framing piercing blue eyes. Her slender frame and pale complexion complement a sailor-style uniform accented by a ribbon headband and thigh-high stockings.

In *Dungeon Travelers*, Sasara adopts the role of a defensive fighter, wielding the skill "Presidential Power" to bolster her shield-based protection. This spin-off transports her into a fantasy RPG realm, though documented sources omit specifics of her personal journey within this setting.

The surname Kusugawa, derived from characters symbolizing endurance and flowing water, echoes her gradual emotional resilience. While her primary narrative arc traces her shift from isolation to tentative vulnerability, expanded backstory or development beyond her core relationships remains absent in ancillary media like OVAs or films.
