Sekai de Ichiban Oppai ga Suki!

巷で噂のイケメン女子・市原千秋が好きなもの。それは…おっぱいです。 「今日も最高のおっぱいだね！」「今日も最低の挨拶だな」 おっぱい大好きイケメン女子×美乳ツンデレ女子の、ちょっぴりおバカな百合コメディ！

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.
