If the point of Alcatraz's Labyrinth is to protect/hold the Scripture, why is she out of it?
It's a mystery.
Sunao is a Burial Agency reservist, correct?
She's a church agent in training, I think the Burial Agency is something else.
And aside from Sunao, Hibiki, an unwitting Chikagi, and Alcatraz, are any of the other characters in the story 'abnormal' in any way?
Harriet/Marie/Lorentz (from the second drama CD)
Are Hibiki and Chikagi as hella gay as other media makes them out to be?
It's probably just baiting but they hint a lot at Chikagi at least being probably gay. Lots of fake outs like "I like you!" "WAIT" "as a friend!" "oh"
Is this your translation, and if not, is this a complete translation of all Mahou Tsukai no Hako content?
It's not mine, looks like someone did a kinda shitty novelization of the first drama CD?
Do you have access to the manga raws, or are there translations?
I don't have them, I know there's a scanlation into Chinese on Sumisora though.
