Jun Sakurada has withdrawn from the outside world during his parents' absence, and to cope, he orders products online and returns them, but when a website instructs him to order a beautifully rendered doll, what arrives in the morning cannot be returned.
Peach-Pit (ピーチ・ピット Pīchi Pitto) is a female manga artist duo in Japan, made up of Banri Sendo (千道 万里 Sendō Banri) and Shibuko Ebara (えばら 渋子 Ebara Shibuko). Their group name derives from the diner hangout Peach-Pit from the TV show Beverly Hills, 90210. Although both have similar styles, with some artwork it is possible to identify which artist drew it. Both are known for their bishōjo styled works. As noted in their books, they are both Geminis and have "Almost flushed our phones down the toilet...twice."
The two of them grew up together and went to the same elementary school and have been best friends ever since. Both started as doujinshi manga artists, but not as Peach-Pit. Then they were scouted by Dengeki Comic Gao!. In 2008, one of their manga, Shugo Chara!, was awarded the Kodansha Manga Award for best children's manga. Shugo Chara was also turned later into an Anime television series.
I will admit, I'm not quite sure what the purpose of some of the events in this volume was, but I'm going to guess that all will be clear next volume (which I think is the last one).
