You basically understand it already. The Danmachi manga stopped immediately after Bell and Ais's dance. It was picked up again and called "Danmachi 2", and you can find it under that name on Mangadex. However, that only covers part of Haruhime's arc and hasn't even finished that.

If you want Danmachi manga, your best bet is the Sword Oratoria manga. That's all the way up to the end of the Xenos arc. Ironically it includes several aspects of the story that were only in the main series LN; it's as if the manga artist has decided to take on both series in the SO manga.

So i bought the 2.0 vol thing, it starts at the fox girl arc. Does that mean i have to read other vols to gdt the apolloarc?

Apollo arc isn't adapted to manga and won't be. Danmachi 2 to the best of my knowledge only covers part of Haruhime's arc. Anything past that in the main series hasn't been adapted to manga.

Again, if you want good Danmachi manga content, read SO. That's on Mangadex for free.

Thank you.
