"ビッチ" reminds of Bitch-sensei from AssClass. Yeah I agree Inugami has more of a varied(?) style of speech. Although it might be there for the funny man gag. Aki too does not use very feminine language (maybe as the straight man). That's cool with me tho.
What just got me a bit taken aback was when Nezu was featured eating cheese. The eng ver was somethong along the lines of "sex in my mouth". Now that's just a bit quirky even for me.
Anyway God bless the translators, cleaners and typesetters of Sexy Akiba Detectives for bringing this to us, and I look forward to more chapters to come.
