I recently remembered something I read on the Homeland a long while back, and I'm hoping I could get a second opinion or some confirmation on this.
I vaguely remember reading some speculation that Marine is or was involved with the doujin circle IOSYS. As far as I can tell no concrete proof came up (at least from what I could find on Kiwi search), but I was listening to some of their stuff earlier, and one of their vocalists certainly does sound a bit familiar. Anyone else hear it or am I just tweaking?
