世界で一番おっぱいが好き! [Sekai de Ichiban Oppai ga Suki!] #4

Volume 4 of Sekai de Ichiban Oppai ga Suki! from Kadokawa arrives with a vibrant cover featuring a confident young woman in a colorful floral yukata — her purple hair and knowing expression commanding center stage — while a shorter, wide-eyed blonde girl reacts with visible alarm in the background. Created by Konbu, the series continues its playful, comedic tone, and this volume's cover art captures that blend of bold personality and flustered energy that fans of the series have come to enjoy.
