Why is there dakuten on the "ん" in this image? (ん゙)

Does "ん" really have a dakuten version?

**My Research:**

So my reasearch has been a little bit unusual for this one, but I found the
following from reddit's
[r/learnjapanese](https://www.reddit.com/r/LearnJapanese/comments/70pisv/katakana_irregular_voiced_consonants_manga/dn4ygxm/):

> Dakuten/handakuten on kana where they would normally not be found can imply
> a muffled, nasal, or slurred sound.

I also found some sources on this stack exchange as well. [Their
question](https://japanese.stackexchange.com/q/32622/22352) was about dakuten
being applied to あ.

As @naruto notes:

> あ゛ used to be commonly used in manga to express an exclamation — "aagh!" or
> something like that. I feel it has become less common (if not rare) these

On [Wiktionary](https://en.wiktionary.org/wiki/%E6%BF%81%E7%82%B9), I found
that ん゙ can signify a guttural "hmmm?"

Finaly, on [Wikipedia](https://en.wikipedia.org/wiki/Dakuten_and_handakuten),
I found the following:

> In informal writing, dakuten is occasionally used on vowels to indicate a
> shocked or strangled articulation; for example, on あ゙ or ゔ. Dakuten can also
> be occasionally used with ん (ん゙) to indicate a guttural hum, growl, or
> similar sound.

**My conclusion:**

I believe that you're looking at something that is informal. For the most
part, it looks like someone is saying "hmmm?" in a guttural, excited, or
muffled matter, depending on the context.
