In Shinkenger, there is of course only one Inroumaru to activate one Super Mode per member at a time, and one Kyouryuu Disc for the same thing regarding Hyper Mode. And, yes, both are in possession of Takeru (or Kaoru, for a few episodes). Here in Dive, Takeru has entered the Digital World with both items.
In order to make things easier for any current or potential future Shinkenger members in the game, I figured I'd make note of a possible way to handle this...
Within reason, if your Shinkenger is somewhere separate from Takeru and needs use of either the device (which includes usage of the Mougyuu Bazooka) or the disc, you can feel free to have it NPC'ed that Takeru sends them either item through the D-Comm or D-Reader. If they're in the same place, then, well, obviously he can just toss it to you, which I'll gladly do myself when asked. :p
This is of course barring any plot reasons why this may be rendered impossible. Such as, for instance, if Takeru and Coronamon were both rendered unable to act or trapped in some manner where they couldn't pass the devices onto someone else. Or, if Takeru (or another Shinkenger) is in use of one of the devices at the exact same time.
The only thing I ask is that I'm shot an AIM message @ Infinity Greymon to tell me it's going on. ^_^
