Solo Leveling: vol. 9

Jinwoo follows the call of the system and returns to the double dungeon that started it all in the hope of finally receiving some answers. What he doesn't expect is to find his toughest opponent yet! Meanwhile, an S-rank gate looms over Tokyo, and after the loss of their strongest hunters, Japan turns to outside help - but with a worldwide increase in magic beast activity, only one S-rank hunter accepts their offer...Will that be enough to stop the magic beasts before they lay waste to Japan and beyond?

Translated from the original Korean (which makes this manhwa, rather than manga!)
