Integrating the World

What is the introduction? Can it be eaten? I've heard people say it's useful, so let me introduce it more. After Attack on Titan merges with other worlds, the plot of Titan completely changes. Ah~ Lengliegu Boldo, isn't that thing from Dark Souls? In addition to Dark Souls there are more unknown worlds that merge with Attack on Titan. What other stories will there be after the integration? Fusion World, as the name suggests. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
