The story about 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.
