Illusory Daitou TV is an idolasphere in Tokyo Mirage Sessions ♯FE.
Illusory Daitou TV is first visited in Chapter 3. The entrance is located at Daitou TV. Itsuki's party first enters the Idolasphere when pursuing after Barry Goodman, who is possessed by cursed Draug, and is subsequently the final boss of the area.
Illusory Daitou TV is a large dungeon comprised of stone pathways, wooden bridges and Japanese pavilions. In Chapter 3, the party enters one of the pavilions, agreeing to help a director Mirage prepare for a performance. First, they must light up four lanterns in the four cardinal directions before preceding to the next floor. There, they must talk to a Mirage who will hand them two Light Essences, which must be used to adjust the lighting in four lantern rooms to the satisfaction of the Mirage inside. Afterwards, the director Mirage asks a party member to sing a cover of Dia Sweet Witch, which Kiria performs. The final task is to deliver three fixed scripts to three different Mirages within a time limit to proceed, or Itsuki must try again. After this, the party finds Barry and Draug, and defeats Draug.
The party later revisits Illusory Daitou TV in Chapter 5, in pursuit of Dark Yashiro. While in pursuit, the party stumbles against a thick and impassable wall of Performa. Tiki informs the party that a massive flow of Performa can be found at Illusory 106 and Illusory Studio. When the flows of Performa are cleared at both locations, the Performa wall at Illusory Daitou TV will clear, allowing Itsuki to find and defeat Dark Yashiro.
