Watarirouka Hashiritai 7
Watarirouka Hashiritai 7 (渡り廊下走り隊7) (also known as Warota (ワロタ)), formerly Watarirouka Hashiritai, was an AKB48 sub-unit. The group was announced in October 2008 and debuted on January 28, 2009 with their single Hatsukoi Dash/Aoi Mirai. On November 14, 2013, the group announced their disbandment. Their final concert was held on February 9, 2014 at Zepp Diver City, Tokyo.
The group was a modern revival of the Onyanko Club unit Ushirogami Hikaretai, active from 1987 to 1988. The 7 came from the addition of Komori Mika and Iwasa Misaki (Valentine Kiss), giving the group seven members. Urano Kazumi joined the unit only for their last single, having already graduated from SDN48 by that time.

Okashina Sisters
Okashina Sisters (お菓子なシスターズ) was a one-shot unit from AKB48 that was considered the predecessor to Watarirouka Hashiritai. Okashina Sisters consisted of Ota Aika, Nakagawa Haruka, and Watanabe Mayu, all of who went on to become members of Watarirouka Hashiritai.
Okashina Sisters was formed in 2008 to perform the ending theme for the anime Miracle! Mimika, Koi no Chewing. However, the song was never released as a single of its own, and instead became a coupling song for Watarirouka Hashiritai's first single Hatsukoi Dash/Aoi Mirai.
The name Okashina Sisters is a pun on okashi (お菓子), meaning “sweets”, and okashii na (可笑しいな), meaning “amusing” or “strange”.
