The battle of London, Third and Fourth Impact, the Eclipse, the devil war. All of these events tore a hole in fabric of the multiverse, a tear that opened up to the Attack on Titan world. With the convergence of worlds a new, grand war will begin unlike nothing before. Crossover with Hellsing, Evangelion, Berserk, Devilman Crybaby, Godzilla, Sekiro, Bloodborne, Metal Gear rising, Dark souls, Demon's souls. More may be added later on and none are owned by me.
