The manga for this property started in 2010 and has twelve volumes to its name as created by Akinari Nao and Kenji Saitou, which Yen Press is currently releasing.
The upcoming film project Trinity Seven: Eternity Library and Alchemic Girl is working through the big push on the production ahead of its debut in two months and that’s now landed us a new trailer for it.
Set for a February 25th, 2017 debut, we now have a good listen to the theme song for it with ZAQ’s “Last Proof” single.
