What does ほん mean?


Good evening, I was reading a manga and I'm not sure if it's ほん or if it's
another expression, because something appears first that seems to be a zero,
something like this: 0ほん...

It's **ぽん(pon)** not **ほん(hon)**. And as far as I can tell, it's simply a
onomatopoeia, aka a word that mimics the sounds "pon!"

The circle on top is called 半濁点, which means half-voiced-dots. They only exist
for the ha-line of the kana's (はha, ひhi, ふhu, へhe, ほho), and turns them into
ぱpa, ぴpi, ぷpu, ぺpe, ぽpo.

I will not extend my answer beyond 半濁点 here, but please look at
[this](https://blog.nihongomaster.com/japanese-hiragana/) for all possible
sounds Hiragana can represent. It also explains 濁音 and 半濁音.
