In an early draft of what would later become Shakugan no Shana, Yashichiro Takahashi set the story in a different dimension and described the main character as having the initial personality of Shana, but the appearance of an older woman similar to Margery Daw.
Shortly before writing Shakugan no Shana, Takahashi made his debut as an author with A/B Extreme, which was awarded an honorable mention in the eighth Dengeki Novel Prize by MediaWorks (now ASCII Media Works) in 2001 [REF].
