Sora was supposed to 'return' after Ruler of Rules. However, his twisted fate brings him to another world. Whats more, our 'Hero', Sora, appears in the middle of a raging battle. If it couldn't get any worse, he gets killed the moment he appears in this new world. Well that would be expected, if one was transported in the middle of a battle, right? Wait! The story can't possibly end in the first chapter - can it?
