I've Been Killing Slimes for 300 Years and Maxed Out My Level, Vol. 15

HAPPY BIRTHDAY TO ME!I’ve been killing slimes for 300 years, and my family has finally decided when my birthday is! We didn’t have a date until now (mainly because I forgot it…), but I’m so excited for whatever my daughters have planned! Later, I meet the goddess of fate (I can’t be surprised anymore!), I help out a phantom thief (and my family grows), and then I visit a strange land where there are no slimes! I’ll share another pair of drama CD scripts at the end, so don’t miss it!
