  • Various characters from the .hack franchise can be seen during the 3 OVAs. Some of them are not necessarily the characters themselves, but rather players using similar models. Some of those include Atoli, Aina. Alkaid, Piros the 3rd, Natsume, Grein, Silabus, Gaspard, Kuhn, Orca, Wiseman. The real IYOTEN and Asta appear. Phantoms of the actual Ovan, Shino, Tsukasa, and Aura are seen. Sakuya, Mary and Tobias are modified models of Kite, BlackRose and Balmung, respectively.
  • Shamrock's Guild, Yata Mirror, is a reference to Yata's chamber in the Serpent of Lore.
  • In the final episode of Quantum, when players are seen trying to keep the infected bugs out by pinning themselves onto the gate, Orca, or a player similar to Orca, can be seen in the middle of the group. Silver Knight also appears, helping the remaining players to escape to the Chaos Gates (although it's not confirmed if that's him).
  • Interestingly, Sakuya's infected hand is her right arm, which matches Kite/Shugo Twilight Bracelet's on their right arms.
  • The episode titles Walking Party, Wired Prisoner, the Worldend Pallbearer can be shortened to WP. This may be a reference to wave-particle duality, which is a "central concept of quantum mechanics".
