宴のスター特別プロジェクト

Missing, extremely new, or very obvious to obtain.

This achievement has no cultural references in the English and Chinese versions. It is likely specific to the game. The characters to obtain this chive are all under the IPC, with the Stonehearts being directly under Diamond's leadership and with Dr. Ratio being a member of the Intelligentsia Guild, a faction heavily sponsored by the IPC. They all played a part in Penacony now becoming an asset of the IPC.
