How were the English translations of character names for Hunter x Hunter conceived?
Because this is how it translates to phonetical English.
Furikusu basically sounds as &quot;Freakks&quot; (Sounds like Freak but with a bit more emphasis on k sound).
Kirua would be pronounced as Killua.
Kuroro is Chrollo.
This is because of the lack of vowels and consonants in the Japanese language. To compensate for it, they add a vowel of their own after a consonant. For example -

The English word &quot;Freak&quot; would be pronounced as &quot;Furiku&quot;.
&quot;Accent&quot; would be pronounced as &quot;Akkosento&quot;.
&quot;Hunter&quot; would be pronounced as &quot;Huntoru&quot;

Trust me, they are all right.
