The beginning might've been a little text heavy for me. Sorry for the lack of grammar check, but since I have another question for you readers, I will update the grammar as much as possible.

Since this doujin uses a bunch of terminology, I'm not sure if I have found all the corrects ones.

The Obvious ones:
魔神(人)・沖田総司 = Devil Okita Souji (Okita Alter's nickname)
魔術協会 = Black Magic Association (off: Mage's Association)
降霊科(出身) = (a person from) The Spiritual Evocation Department

The not so obvious:
人理焼却事件 = Human justice incineration event (currently Human order incinceration incident in my tl).
査察官 = Inspecting Official (I should change this to just Inspector).
緑 = Green. Appears to have something to do with Chaldea and how their contract system works.
第三霊基 = Third Spirit Base (tl as Third Spirit Origin, as it what I found trying to google search it)
対魔力 and 退魔ニン = Opposite Magic Power and Opposite Magic Resistance/Endurance?

Other notes:
Page 10 and 11: Appears to be a discussion between Sherlock Holmes (Servant) and what might be an old man (the player?) possessing the body of the female protagonist. I really didn't understand most of these 2 pages, so sorry for the mess.

"rThe" typo on page 14 >_<

I will fix most of these as soon as I get input from more knowledgeable readers.

Man, Okita Alter just can't get any lovey dovey stuff can she?

They went pretty much overboard with the censoring here. Like seriously, what the hell.

Base +7, baguete +6, gseed +6, prinnymask +6, see-eff +8

Wtf it's like someone poured ink on their crotch

Base +9, baguete +6, prinnymask +6, miaolebaiyue +6, see-eff +8

I'm guessing Gudao was too hard to draw or something? Not a big fan of the Ken doll here.

Base +5, Dark Mac -12, renge +6

Good lord the censorship in this one is ridiculous

Base +8, prinnymask +6
