I highly doubt this game is actually made by Shueisha(or this so called "Shueisha games"), I can't even find any info or news about this. Not even on Shueisha's official Twitter or their websites nor these artists' twitter, fanbox, pixiv, you name it.
But I have searched everywhere, unless all of these artists signed an NDA, otherwise I found it hard to believe they actually got the rights.

They have used the same assets from promotional assets and fan-arts such as
https://www.pixiv.net/artworks/82255014 , https://www.pixiv.net/artworks/72859876
Though they claimed that "Our subsidiary is officialy licensed and all artists were credited & compensated for their time"

What makes me even more suspicious is that this game supports Japanese right?
Then how comes the japanese store page felt like half-baked version of English one?
Not even the trailer is in Japanese.

Oh by the way, "You" may just warn me or ban me from this discussions.
That won't stop me from reporting you, which I already did.
