English Translation Terrible.

[Espon]

Some of the translations are way off or changed to suit what they want. Haurchefant is a prime example of it. Why did they feel the need to change it! If our boy is a perv let him be.

Because some character types don't translate well to other cultures. While it's a common trope in anime, in English people tend to get easily offended these days so it's probably less of a headache for SE to simply change a character's personality instead of dealing with numerous people crying about some NPC that flirts and wants to get into bed with the player.
