Infinite Dendrogram (Manga): Omnibus 6

Contains the full Volumes 11 and 12! Can a City Catch a Break Already?The attack continues and the situation in the City of Duels worsens by the moment. Ray Starling steps outside the city's walls to stop the mastermind behind it all...but with Franklin's menacing RSK standing in his way, has Ray finally met his match? And even if he can overcome this, is he ready for Giga Professor's "Plan C"?Then, Franklin puts his Monster Factory into overdrive outside Gideon, causing beastly hordes to loom over the city. Something else seems to be stirring beneath the duel arena as well... Ray finds himself hard-pressed to handle the overwhelming crowd that stands against him, even with his own reinforcements at hand. It's clear that a job like this calls for area denial on a massive scale--and luckily for Gideon, Altar's very own King of Destruction is ready to step up and toss his own brand of chaos into the fray!
