Luminous Yellow of Treasured Gem Squadron Luminous X, Mitsumune Sayaka, goes undercover as bait to lure out enemy soldiers involved in Deathgandara's series of female abductions. Her trap succeeds, but the soldier is killed by a monster before revealing any information, leaving the victims' whereabouts unknown. Witnessing this tragedy, Sayaka transforms into Luminous Yellow and resolves to fight Deathgandara's monsters. From the monster's words, she learns that Deathgandara's new general, Deryu, is behind the abductions. Deryu confesses he kidnaps women solely to satisfy his own pleasure. Sayaka, haunted by past trauma from an assault by an unrelated man, swears she will defeat Deryu at any cost. Tracking Deryu's next move, Sayaka arrives at the scene—only to come face to face with General Deryu himself. Recognizing his face, she is shocked to discover Deryu is actually Tebawa Ryuji, the very man who assaulted her in the past. Trembling with rage, she attacks him, but every strike is dodged, and she is ultimately captured. Once again, Deryu's sinister hands close in on Sayaka's body... [BAD END]
