Ding-dong! DEAD-dong! Class is in session, but even DWMA is preparing for the annual Death Festival held on Halloween. But while Death City is abuzz with excitement and delight, something sinister is brewing within its shadows...and it seems the girls' carefree school days are in for a rude awakening with a shocking betrayal! Can DWMA stop the nefarious witch Shaula Gorgon's schemes before it's too late? And will Tsugumi ever get to make her choice?! It's a savage but super-fun conclusion!

Tsugumi Harudori is in love with life at DWMA, but she still hasn't made a decision on whether to take Meme or Anya as her meister. Anya has delivered an ultimatum: Tsugumi must make her choice by Halloween--and the clock is ticking! Can Tsugumi make up her mind in time, and without hurting one of her friends? It's a savage but super-fun life!

The attack on Eternal Feather is a cruel reminder that there is very real danger out there for the weapons and meisters of DWMA. Tsugumi is more determined than ever to develop her skills so that she can defend her friends in the future. But the road ahead is filled with challenges...and silliness!
