@mnmega: Those terms are from the furigana (written in katakana in this case), which like they're used in LN's, have nothing to do with the kanji (Because author thinks it's cool).
OCR'd from Raw: (Then cross-referenced with WN to confirm accuracy)
錬聖術 (アブソリュート・クリエイション) [Absolute Creation]
眷属調教 (ルナティック・セクシャル) [Lunatic Sexual]
I don't think the mistake is regards to similar looking kanji nor pronunciation. But I don't know Japanese so could be completely wrong.
