Dungeon Friends Forever, Volume 2 (Dungeon Friends Forever #10-18)

Ryuka is the overlord of a fearsome underground dungeon, but that doesn't scare off her old childhood buddy Van. He's always fighting his way past her mightiest monsters just so the two of them can hang out. And let's be honest - they really ought to be dating, but they're both a little too dense to figure it out. Thankfully, Ryuka's most powerful monsters are only too happy to try and help them out from behind the scenes. However, things take a turn for the worse when Van is forced to battle against his greatest enemy to date... Ryuka's mom!!
