P-item pool type
Gakuen Idolmaster splits P-items across several separate pools — not every P-item lives in one shared list:
P-items listed in the game's official P-item dex, obtainable during most standard Produce runs.
A SEPARATE pool that only appears in the H.I.F chapter — the way you play and unlock it differs from regular P-items even though it's still filed under the official dex.
A SEPARATE pool tied to a specific story chapter (e.g. N.I.A). It activates IMMEDIATELY on equip rather than waiting for a condition, and comes with a trade-off: triggering the effect also grants points to the simulated rival in the audition — many players deliberately avoid triggering it just to keep the baseline audition bonus.
A SEPARATE pool used only in Contest mode, distinct from both the regular pool and the chapter-specific pools.
Proof of First Battle: Sena+ belongs to the Regular pool (P図鑑) — part of the official P-item dex, not a Custom/Challenge/Contest P-item.
