X-DEN samples three songs that have been in the Kaiden course at some point, with different songs used for the Single and Double versions:
- The Single version samples 嘆きの樹, 灼熱Beach Side Bunny and 卑弥呼, representing beatmania IIDX 21 SPADA's Single Kaiden course (DJ TOTTO made his beatmania IIDX debut in SPADA).
- The Double version samples ピアノ協奏曲第1番"蠍火", Bad Maniacs and 天空の夜明け, representing beatmania IIDX 23 copula's Double Kaiden course (HuΣeR made his beatmania IIDX debut in copula).
X-DEN also samples Highcharge Divolt, 冥, AA, Valanga, the beatmania IIDX 13 DistorteD music selection sound, and the pop'n music 6 difficulty changing sound in both Single and Double versions.
- The last two are references to the Kaiden and HELL courses, which were introduced in beatmania IIDX 13 DistorteD and pop'n music 6, respectively.

X-DEN's title card.

X-DEN was added to beatmania IIDX 26 Rootage on February 26th, 2019 as the ONE MORE EXTRA STAGE in celebration of the 20th anniversary of beatmania IIDX's release. To access it, EX-HARD clear all three stages plus the EXTRA STAGE. The difficulty of X-DEN is determined by the difficulty of the EXTRA STAGE song, e.g. clearing an ANOTHER chart will give you X-DEN's ANOTHER chart.
- X-DEN is the first ONE MORE EXTRA STAGE song not tied to an unlock event since DIAVOLO in beatmania IIDX 19 Lincle.
- From February 6th, 2020, its charts can be purchased in beatmania IIDX 27 HEROIC VERSE via トーンディスチャージャー.
- As of beatmania IIDX 28 BISTROVER, it is available by default.
When X-DEN is played in bearmania IIDX, the arcade LED ticker displays "KAI-DEN".
- The X in X-DEN is the Greek letter chi, which is pronounced as kai. X-DEN is thus pronounced as kaiden.
X-DEN marks the first collaboration between DJ TOTTO and HuΣeR in BEMANI.
- Befitting the song's name, both of them are Kaiden-rank players.
X-DEN's video features ABDI and Echidna, representing DJ TOTTO and HuΣeR respectively.
X-DEN's artist, T.Σ.Generation, might be a pun on T.M.Revolution.
