  • In the episode, Thouser can be seen dancing to Zero-One's MetalCluster Hopper transformation jingle. As of the episode's airing, Sony updated all AIBO units to perform the dance upon the usage of the DX MetalCluster Hopper Progrisekey in the DX Zero-One Driver.
  • This episode marks the very first time MetalCluster Hopper's Let's Rise standby music is played. The tune was previously played in A Miraculous Rematch!? Aruto VS Fukkinhoukai Taro: Fateful Gag Battle!, but only as a background sound during Aruto's pun on MetalCluster Hopper.
  • As Aruto is transforming, Ark-Zero can be seen tapping his finger while his arms are folded. This is a nod to a joke within the fandom that heroes take too long to transform.
  • What happened to Ikazuchi in this episode clearly mirrors the situation of his debut episode.
    • In the said episode, Ikazuchi led Aruto and Fuwa to Daybreak after Jin secretly installed a module into him. Similarly, in this episode, Ikazuchi lead Aruto and Jin to Daybreak innocently to help them after Ark secretly allowed his memories to resurface.
    • In the debut episode, before Ikazuchi could react, he was transformed into a Kamen Rider by getting hacked with a Forceriser. Here, when Ikazuchi tried to revolt against Ark, Ark possessed him and transformed him into Ark-Zero. In both cases, Ikazuchi would scream before losing control.
  • This episode features the last appearance of Zero-One MetalCluster Hopper and Kamen Rider Naki.
