SKE48's 17th single "Coquettish Juutai Chuu" (went on sale on March 31) sold 640,000 copies during the first week, coming out on top of Oricon's latest weekly single ranking.

On the other hand, NMB48's single "Don't look back!" which was released on the same day as SKE48, was in second place with the first week sales of 447,000 copies.

The first week sales for "Coquettish Juutai Chuu" exceeded the group's previous best record, 539,000 copies, which they made with 11th single "Choco no Dorei" (released in January). 

Also, as this is their 13th consecutive No.1 single, they have renewed their second best record of "the number of consecutive chart-topping singles" for female group, following AKB48's 26 singles.
