"Yuhn."
The u being kinda like "oo" but quicker (thats why i put an "h" in lol).
Once i pronounce a word like i think it is especially a name in a game i find it very hard to change the way i say it. Thats why my friends get mad at me when I say stuff like "spy-ra" instead of "spee-ra" and "fa-rees" instead of "fa-riss".
