"QUANTUM" is a CD featuring many all-new recordings for the first time since "DEVOTION," released on June 14, 2023. It contains new songs, including the suite "QUANTUM" performed on the nationwide tour [TMNETWORK TOUR 2026 QUANTUM], held on a scale of 20 performances across 13 cities (2 of which were additional performances), as well as songs recorded in new arrangements for the tour. While the memories of the tour revive together with a new sonic resonance, it also becomes a record of the latest form of TMNETWORK, moving further into the future after its 40th debut anniversary year. The Limited Edition comes with a 40-page booklet and goods (QUANTUM CUBE x 4 / stickers). It comes in a slipcase box.
