Ricoh 0.7???????????????????????So-net???

It appears to be a front mounted wide angle converter.

Sounds like an accessory for the GR (one's already on the market).

They are not short on patents.
Ricoh is committed to become world's number two manufacturer of patents in the mid-term.

If I understand the google translation correctly, the adapter is designed for cameras with 1/1.7" sensor.
Maybe something like the Wide conversion Lens GW-2 for Ricoh GR Digital IV.

Or perhaps the Q? Maybe that is their way of producing a wide prime

Of course, a joke, but no one can beat Pentax when it comes to bizarre.

Render to Caesar the things that are Caesar's (Mark 12:17): the initial source of information is Egami Ricoh 0.7倍ワイドコンバーターの特許 : エンジニアの嗜み

The optical diagram in the patent shows the 0.7x converter in front of a 4.6-17.8 mm f/1.9-3 zoom lens made for 1/1.7" sensors (equivalent focal length: 21-84mm).

So, the answer for the Q7 Wide perhaps?
