Minecraft: The Manga, Vol. 2 by Kazuyoshi Seto

[Viz] An official Minecraft manga adventure! Peaceful life in a perfectly constructed town bores ten-year-old Nico into mischief. Riding creepers while they explode is fun and all, but what he really wants is to escape the blocky confines of his home and take his crafting skills on an adventure to the ends of the world. Just how big is the world, anyway, and what could possibly stand in his way? Nico has set off on an adventure to the end of the world! He now has what every great adventurer needs—an adventuring party. Turns out it’s good he has friends with him, because he’s about to face a spider larger than his whole party combined!
