Illusory Daitama is an Idolasphere in Tokyo Mirage Sessions ♯FE.
Illusory Daitama is the first Idolasphere visited. The entrance is located at the Daitama Observatory. It is first entered in the prologue, when Tsubasa is dragged into the Idolasphere and Itsuki rushes in after her. It is here that Itsuki manages to purify the Mirages Chrom and Caeda, and he and Tsubasa subsequently become their Mirage Masters. The boss at the end of the Idolasphere is Garrick, in control of a possessed Teru Gojuin.
The Idolasphere itself is short and straight-forward. It features no puzzles to solve and takes the player on a linear path with floors separated by elevators and the occasional branch leading to a treasure box. It is also the only Idolasphere in the game with a recovery station that restores the party's HP and EP when accessed, and the only Idolasphere that does not feature warp panels. At the end of the path, outside the boss chamber, there is a ledge that can be jumped down to return to the entrance.

In New Game Plus files, close to the sealed areas of Illusory Daitama is an out of place Slattern. This is the Grandmaster of the Mirage Dojo, and has a request: "Versus! Grandmaster Mirage", where you must find his 6 pupils, which are fellow Slatterns, within the various Idolaspheres beyond Illusory Daitama, fight and defeat them, then bring back a piece of the Mirage Dojo sign they safeguard. The kanji on the Dojo signs read as Mirage Dojo (魅羅亜呪道場, Miraaju Dōjō)?, with "Mirage" being written entirely in phonetically similar kanji. When defeated, they also drop 10 pieces of Detritus. Each one of of the masters has a unique strategy.
Master Alpha is the first Master of the Mirage Dojo, and can be found in Illusory 106, somewhere on Floor 3. His battle will have him using Debilitate on the party and buffing skills on himself. Use both Dekaja and Dekunda, either as skills or items.
Barring that, use Tarunda and Rakukaja to minimize the damage from Revenge Arts.
Master Beta is the second Master of the Mirage Dojo, and can be found in Illusory Shibuya, somewhere on Floor 2 within the First Block. While he may have one attack, he has the passive skill Revenge Arts, which allows him to always attack anyone who attacks his weapon triangle weaknesses, and this does more damage than Retaliate. Counter this by using an Attack Mirror/Tetrakarn then attack him. As Revenge Arts is always a physical attack, it will react to Tetrakarn, and repel the damage back onto Master Beta.
Master Gamma is the third Master of the Mirage Dojo, and can be found in Illusory Daitou TV, somewhere on Film Set A's first floor. He will cycle between Attacking and using Spirit Leech and Life Leech, the latter of which can be countered by using Magic Mirrors.
Master Delta is the fourth Master of the Mirage Dojo, and can be found in Illusory Daiba Studio, in the rightmost side of the northern hallway. Master Delta is a master of inflicting various status ailments, his one attack is a Physical Beast attack that has a chance of inflicting Stun, and has a passive ability that greatly increases the chances of inflicting an ailment so use Mamori's Raindrop Melody Special Performance to buy time as you hammer at his Ice weakness.
Master Epsilon is the fifth Master of the Mirage Dojo, and can be found in Illusory Area of Memories. The gimmick of Master Epsilon's fight is using Session Overkills gained from killing his Troll Disciples to attack him, outside of using Special Performances on Master Epsilon himself.
Master Zeta is the sixth and final Master of the Mirage Dojo, and can be found in Illusory Dolhr. The gimmick of Master Zeta's fight has him use Megidolaon and Diarahan in that specific order, meaning either using Itsuki's Strike a Pose Skill to give everyone a second turn and kill Master Zeta in one turn of combat or using attacks that can inflict Seal on Master Zeta to cripple him.
The Grandmaster is your seventh and final opponent in this chain of special fights. The Grandmaster in the beginning will use Thoron, Excalibur, Bolganone, and Fimbulvinter in that order, and began targeting Itsuki, then changes target to the teammate to Itsuki's right, the teammate to Itsuki's left, and then back to Itsuki, until his health hits the red. Once there, he will then use Concentrate then Megidolaon until the party goes down, so get rid of him ASAP.
