Queen Malta, a world-renowned East Doroan singer, dedicated her career to fostering peace between the warring nations of East and West Doroa through her music. She aimed to bridge their political and cultural divides by organizing a high-risk concert in West Doroa, convinced her performances could inspire unity and halt the conflict. Despite escalating tensions, she pursued the event, believing artistic dialogue might avert war.

Prior to the concert, she hired marksman Daisuke Jigen as her bodyguard, their relationship strictly professional yet ambiguously defined. During her performance at the West Doroa International Concert Hall, sniper Yael Okuzaki assassinated her with a fatal headshot mid-song. Investigations later uncovered the killing as an East Doroan government conspiracy to frame West Doroa, providing pretext for military escalation.

Her death intensified hostilities, transforming her into a martyr symbolizing fractured diplomacy. Jigen, haunted by guilt over failing to protect her, embarked on a vengeful pursuit of those responsible. Though publicly an idealistic peace advocate, scant personal details hinted at deeper complexity, notably her habitual smoking.

Exclusive to *Jigen’s Gravestone*, her legacy anchors the narrative, driving its central conflict and themes of political manipulation without expansion in other media.
