Sekai de Ichiban Oppai ga Suki!

From the author of Jahy-sama wa Kujikenai! comes the story of the cool Ichihara Chiaki and her big breasted friend, Harumi Hana. Chiaki is a member of the archery club and is also a huge breast fetishist. If she doesn't fondle breasts, she can't perform at her best in archery. The big breasted tsundere named Hana attends a different school than Chiaki, but still goes along with Chiaki's requests.

Just how far will Hana go for Chiaki?!
