August 19, 2012 - New Blue Sky played at Toll's birthday concert, "It's A Now!", at Club Citta (Tokyo). After that, we have a new "It's A Now!" almost every year at Toll's birthday.
2013 - Shime on vocals/guitar, Kaname Ohta on bass.
2015 - Shime on vocals/guitar. Tochikatsu Uchiumi (Carol) and Masafumi Minato (Dead End) were guests.
2016 - Kenta Harada on vocals/guitar, Kaname Ohta on bass, Masato Yagi on vocals/guitar.
I'm not sure about other members, but Kenta Harada was playing with Toll on Blue Sky at least until 2023.

I'm a bit lazy rn but there's more info about yagami toll and the blue sky here.
