SPSD-73 Sparkle Star Mel Pure! The fleeting glow of a star

Shadow Zone gathers Nageki (the power of crying) in order to erase the light of the universe and turn it into darkness. To counter this movement, Mutant, an emissary of the Comet Kingdom, seeks out the legendary warriors, the Melpure, from a parallel world. As they fight daily, Shadow Zone executives lurk nearby, intent on destroying Melpure from within. Aria's beloved, Professor Sato (Upsilon), and the fourth Melpure, Shalala, are also present. With more allies, things seem to be going well, but finally, the executives begin to move to destroy Melpure. The scenario for their annihilation is cleverly orchestrated, and the three are increasingly consumed by darkness. Shalala, who hates Abuel's brightness, poisons Abuel and leads him to ruin; Aria is tricked and held captive by Professor Sato; and Capella sacrifices herself to save Abuel and Aria... [BAD END]
