I took this screen shot from Kakenuke★Forward to Our Sparking Youth! (vndb.org). The above character is a semi-generic background character, the unnamed manager at the protagonist's work place. I'm convinced the character artwork is not original to this VN but I can't remember for the life of me where else I've seen it. I went through the list of all other VN's produced by Saga Planet I've played and am still coming up short. He may not necessarily be wearing the same outfit in whatever other source I'm failing to remember.
 
Can anybody else come up with a source for this character?
