Spoilers for the sixth chapter of this DLC, but when you fight Takumi (possessed), it appears he wields Skadi. A nice little touch there.

(Conquest Spoilers!) Shiro accuses Siegbert of holding the sword that killed his father... while holding the Raijinto... oh, the irony.

Just another thing from having seen a playthrough of chapter 3 - you said the enemy children wield the same things, but what does Kana wield? In chapter 2 he was locked as a dragon, but in chapter 3 he uses a sword.

You said the children are in their default classes - this is true for everyone except Shiro, who is a Swordmaster. Also, enemy Siegbert wields Siegfried. I would assume from this that Shiro wields Raijinto, although I haven't seen him battling so I can't confirm this.

Nope.

There is a download link for the full song somewhere, though I can't find it. Also, someone found three of the verses ('In the white light', 'Embrace the dark' and 'A burdened heart') in the My Castle Museum; the Revelation one goes: A burdened heart Sinks into the ground A veil falls away without a sound Not day nor night Wrong nor right For truth and peace you fight Also, from what I can hear, the verse after the Conquest one goes: The path you walk on belongs to destiny Just let it flow All of your joy and your pain Will fall like the tide Let it flow
