A Futaba Sakura memo pad from Persona 5.  A similar set of notepads were released through Ebten for Persona 5 Royal.  this appears to not be part of that set.  The graphic has been used in full for a set of Weiss Schwarz card game protective sleeves.

We tried looking up the origination of this exact artefact, however came up empty.
