Lilium serves as one of ACCA's five chief officers, representing the resource-rich Furawau District, a region culturally inspired by India. Hailing from a prestigious Furawau family, he publicly defended Jean Otus against coup rumors while secretly masterminding the plot alongside Grossular, whom he controlled. Lilium aimed to install Jean, possessing royal Dowa bloodline connections, as a puppet king. This plan sought to leverage Furawau's natural resource wealth to secure the district's dominance and favorable terms within the kingdom.

Initially collaborating with Jean, Mauve, and other chiefs to prevent Prince Schwan from dismantling ACCA, Lilium's true objective was manipulating the political transition for Furawau's benefit. When exposed, Furawau attempted secession, anticipating Dowa's resource dependence would force advantageous negotiations. This strategy failed upon Pranetta's discovery of equivalent resources, stripping Furawau of its leverage. The ultimate status of Furawau's reintegration remains unresolved.

Physically characterized by dark skin, black hair, and brown eyes, Lilium engaged in intricate political maneuvering beyond his district. His actions stemmed from a desire to elevate Furawau's influence, strategically utilizing Jean's royal heritage. Exposure by Jean and Mauve led to the collapse of his ambitions, highlighting his underestimation of their awareness.

Lilium's background emphasizes his political acumen and loyalty to Furawau, positioning him as a key architect of the coup's underlying machinations. His development illustrates a shift from covert influence to overt confrontation, culminating in Furawau's isolation and strategic defeat.
