Gacha Gacha

Gacha Gacha is a shōnen manga by Hiroyuki Tamakoshi. As of November 2008, the first 13 volumes have been published in North America by Del Rey Manga. However, according to the Anime News Network, the series ended in Japan at volume 11 of the second season. The reason for this discrepancy is likely because the series is broken up into two story arcs, essentially two different, unrelated stories, the first being "Capsule", and the second being "Secret". An interview with David Ury, the series' translator for Del Rey, shows that they were planning to release all of both arcs.

Plot
Nanjou Kouhei has been classmates with Hanazono Kurara since elementary school, and he has recently realized that he has developed a crush on her. However, after a fateful trip to Hawaii, Kurara has started to behave oddly at times—specifically acting extremely promiscuous and flirting shamelessly for short periods, then remembering nothing. Kouhei is often the target of this flirtatious and exhibitionistic behavior, leaving him to take the blame when Kurara returns to normal.
