Original Text:
1. もうすぐだぞー
Romaji:
1. Mousugu da zo~
English Translation:
1. We're almost there...
もうすぐ:
This expression means "soon" or "rather shortly".
だ:
だ is a more colloquial and less polite form of the verb です which means "to be".
だ can sound quite rough and abrupt at times, therefore, it is used mostly by male speakers.
ぞー:
ぞ is a particle used at the end of sentences. It indicates assertion and is used mainly by men.
The dash (ー) after the ぞ character is called chouon.
It is primarily used to extend the vowel sound that comes before it.
Although it is supposed to be used with katakana only, manga directed at young children use it a lot with hiragana since it is easier to read that way.
In this particular case, extending the sound of the last syllable makes it feel like the speaker is talking in a relaxed, easy-going way.
