The Unimplemented Overlords Have Joined the Party!, Vol. 6

Shuutarou and his friends safely rescued Kettle, but their relief is short-lived; Kettle starts to attack the group, and right before she loses consciousness, she provides Shuutarou with proof that the mysterious “angels” are slaughtering players. He now seeks even greater strength in order to defeat this new enemy…only for his faithful Evil Overlord Elroad to disappear without explanation! Has the King of Demons betrayed his master, or is this part of a bigger plan?
