Perfect timing with such covers in a way symbolizing Mahiru helping to rescue Shinoa in the current time, and of course Mahiru back with her consciousness to begin with. Having come full circle, it's a nice representation that nothing comes between them!
Hi @HiItsSeraphGacha, if from your view an image is appearing grey, like you are unable to see Mahiru and Shinoa in the image, then it would be best to provide as much details as you can (browzer/device used, screenshots and that) to Zendesk!
A note that Mahiru and Shinoa grace the cover of the seventh volume of the Catastrophe at 16 prequel manga based on the light novels. This is a second manga being released at the same time as the manga that the anime was based on, the main series which has it's Volume 20 cover available to view!
