Short Manga With Good Cover Art

Are there any good COMPLETED manga series under 10 volumes/one shots that have good art? I was planning on getting Tohyo Game but I saw mixed reviews so now I’m considering something else. I was looking at the series Boy’s Abyss and Call the Name of the Night because both have pretty covers (Just to give an idea of what I might like). I already have goodbye eri so please dont reccomend it but i’m open to anything else!
