No, no it doesn't. It would only sound better if you didn't know the language. Nemaki Dasai is literally Lame Pajamas. It's the kind of name that would get you picked on at school.

The name of the goddess is actually Goretaruu/Goltaruu/Goltalu/Gretal, the last bit is pronounced slightly differently from Goretarou/Goltarou/Gretalo. This subtle nuance isn't transmitted well between the MC and other people he meets, And frankly its not easy to translate it well either.
But as you may have noticed. MC has horrible naming sense, and I mean horrible. Whether he's always had it this bad or the amnesia made him like this remains to be seen.
