sound piercer feat. Ritsu - Ai to Bonnou to Rinne to Joushiki no Gokusai Sekai

Surprised that I didn't find this song on RUclips.
This was also played by Staiain during AGDQ 2016.

Thanks for the upload! I heard this during AGDQ this year and my first thought was "yup, gotta' know what song that is".
