The purpose of Queen Malta's performance in West Doroa was to unite the two countries, but she tragically met her demise on stage. The assassination only exacerbated tensions between the nations, with East Doroa, known for its low crime rate, intensifying security measures in anticipation of potential conflict. Despite the strengthened defenses, renowned thief Lupin III successfully stole the Little Comet jewel while his partner Jigen Daisuke became the target of the hitman responsible for the Queen's death: Yael Okuzaki, who was known for leaving his victims underground. Unfortunately, Jigen fell prey to Okuzaki's attack. The rationale behind Okuzaki's decision to target Jigen instead of Lupin remains a mystery, further complicated by the mysterious involvement of Fujiko.
