SKE48's 14th single "Mirai to wa?" (went on sale on March 19) sold 398,000 copies during the first week, and topped Oricon's latest weekly ranking. This marked the group's 10th consecutive chart-topping single.

This single allowed them to become the 3rd female group to have 10 chart-topping singles which has only been achieved by Morning Musume and AKB48. 

Moreover, they accomplished it in 4 years and 8 months since their debut which is the fastest record for a female group.

Also, they are now on the 2nd position for "the number of consecutive chart-topping singles" in female group category. (No.1 is AKB48.)
