Giga Macho can be entered after finishing the Mu Continent dungeon.
The clerk at the entrance initially sells 5 CDs. The CDs must be taken to Maya's apartment to listen to them.
This is the first area where Demon Rumors can be received, since Jack Frost, the subject of the first Demon Rumor, can be encountered here. By making pacts and asking for information, the party can receive the rumor that allows Jack Frost to cast Atomic Bufula, as well as the rumors to adjust its strength.
Initially, The Seedy CD stocks 18 CDs; after spreading the appropriate rumors, Secret CDs 1 and 2 are added to the stock.
Later in the game, Ixquic appears at the Seedy CD and can be talked to to learn about a rumor that the 100km/h Hag is in the building. Once this rumor is spread, the upper levels of the building become accessible. When first entering, Maya is greeted by a demon who explains how demons' rumors become true in Sumaru City just as humans' rumors do. The demons have spread a rumor that personas cannot be used in this building. Maya's party will only be allowed to use items and attacks in battle and cannot use spells outside of battle; however, spell beads may still be utilized. There is a second rumor that can be learned from Ixquic about the 200km/h Fogey.
