S/mileage’s 4th indie single titled Otona ni Narutte Muzukashi has been announced.

The single was first reported when the Mobekimasu concert’s started but it has finally been confirmed to be their 4th single after Fukuda Kanon mentioned on her blog that they had already filmed the PV for it.

This will not be S/mileage’s debut single since they don’t graduate from the Egg’s until 3/27, but it will most likely be their last indie single, so we will most likely hear about the debut single before their joint tour with Mano starts (they are set to debut at the last performance on that date, 4/3).

The release date is set for 3/14.
