Just decided to purchase this, even though I've already purchased both the base game and Ashes to Ashes. I hope this still helps Roar to Heaven out - I've listened to Session 1 on your site, and am really looking forward to Session 2.
...On another note, I am utterly convinced that the Type-10 Hymnal is at least partly inspired by Tsukuyomi Shirabe from Symphogear, because a yo-yo could easily count as being connected to the unit by wire or cable. :)
