Sexy Zone's 4th single "Real Sexy!/BAD BOYS" (released on May 1) sold 139,000 copies in the first week, topping Oricon's weekly single ranking. The first week sales was well over their previous single, which sold 95,000 copies in its first wek.

This is also the 4th consecutive single for the group to top the chart since their debut song "Sexy Zone" (released in November 2011). It's been 4 and half years for a teenage artist to accomplish this since it was last done by their senior group Hey!Say!JUMP in 2008.
