For this PV Mitsui Aika is not in the dance shot due to her injuries. Because Kare to Issho ni Omse ga Shitai has no dance shot, this Single has 3 PVs: the Kono Chikyuu no Heiwa wo Honki de Negatterun da yo! PV, Kare to Issho ni Omise ga Shitai! PV and the Long PV Version Released in the Morning Musume's Official Youtube Channel.
The long version gained international interest when it was posted on the American YouTube frontpage in the "Music" section.
On the first day it got 26,411 copies sold, the highest sold under the leadership of Takahashi Ai.
First single to have a Special Takahashi Ai Graduation Commemoration Edition.
