yeah, in one of the chapter it's using "absolute" as a nameHis name is アブソリュート which can be transliterated into abusoryuuto, which is very obviously meant to be Absolute. Where do you even get Apryuto as a name? He even got his name from his rare skill 絶対悪 "Zettai Aku" which means Absolute Evil in English. "(Absolute Evil) is a rare skill, hence we'll name him Apryuto (WTF is this supposed to mean if it's according to your translation)"
It didn't even make sense.
「そうか…。赤子にしてこの魔力…恐ろしいな。それにスキルはカリスマに王の覇道…そして絶対悪か。上に立つものとしては申し分ないスキルだな。それにアーク家の魔法との相性も良い。だが、絶対悪は珍しいスキルだな。確か初代の当主は持っていたらしいが詳しい効果は分からないな。だが、我が子は将来強き男になるだろう。名をアブソリュートと名付けよう。」
This is the origin of his name.
Just now trying to read the raw manga it turns out they changed the wording on when he's being named a little bit but it still ends up with Absolute in the manga. Did you not see "ソ" in his name?
but nah, it's this apricot name again
btw the manga should change it's cover. it's such dark theme with gore and yet the cover looks like a weird mix of kid with frills
