The Most Notorious "Talker" Runs the World's Greatest Clan manga volume 6 features story by Jaki with art by Yamorichan.

With the mighty Longswordsman Koga by his side, that coldhearted, handsome devil Noel Stollen is ready to found a fighting clan of his very own! But his application is denied by Third Inspector Jenkins, who also lets slip news about the looming threat of the all-destructive Valiant on the horizon. Noel won't be stopped by a mere inspector, nor by a dire Abyssal enemy, so accepts a challenge that will pit his party Blue Beyond against their rivals, the Winged Knights! The party who manages to slay the telepathic beast known as the Dantalion will win clan status, but how can even the ace tactician Noel defeat a monster who knows all his plans in advance?!
