Trivia / Cosmic Star Heroine

• Trolling Creator: The very last chest in the game that contains an item contains a Phial, which according to the game's text, is "an incredibly powerful weapon for Arete!". At this point, Arete has betrayed you, permanently left the party with no way to get her back, and in fact, you battle her in the semi final boss fight in the very next room, where you outright kill her., hence you have an Infinity Plus One weapon no one can actually use.
