Third volume of Hell Mode is available for sale!
The synopsis makes it sound like this is the school arc, but it’s more the dungeon delving arc than anything lol
It does come with a tournament part though!
The world’s opening up in this volume, and I hope it grips your attention!
Huge shout out to Seann, my editor!

Synopsis:
How is “No-life Gamers” as a party name?!

The Academy City arc starts off with a bang! After leaving the service of House Granvelle, Allen enrolls in the Academy together with Cecil, as well as Krena and Dogora who have come all the way from Krena Village. As part of their new life together, they form a party to take on the many dungeons scattered throughout Academy City, keeping in mind their ultimate goal of defeating the Demon Lord. When Allen goes in search of a healer for their party, he encounters Keel, a boy his age with the Cleric Talent. However, Keel comes across as guarded and reticent. Just what secret is he hiding, and how is it related to House Granvelle? At the same time, why is Helmios, the Hero of Giamut, at the Academy, and what does he want from Allen? And what’s this about a martial arts tournament?!
