Yes. Wani did a crossover event in celebration of Kairakuten's 25 anniversary. From Kairakuten 2019-12 to 2020-02, Ishikawa Shisuke, Key, and Higenamuchi did collaboration chapters with one of them making the storyboard while the other does the art. The chapters from this collaboration event that are currently available on Fakku are as follows:

Compensated Cheering (Kairakuten 2019-12):
Storyboard: Higenamuchi
Artist: Ishikawa Shisuke

I Ain't Scared! (Kairakuten 2020-01)
Storyboard: Ishikawa Shisuke
Artist: Key

The last one in Kairakuten 2020-02 hasn't been published on Fakku yet but for that one the storyboard was done by Key and the art was done by Higenamuchi.

Hmm, a collaboration between these two artists would surely produce quite an amazing release.
Actually, if I'm not mistaken, the previous release from Key was indeed a collaboration between the two?
