Shana is the title character of Shakugan no Shana, and a Flame Haze, who appears (and was once) human. At the beginning of the show, she's
only concentrated on her Flame Haze duties, and doesn't even bear a
name. Her name was given to her by Yuji Sakai after she mentioned that
people call her by the name of her katana. Throughout the series, Shana
is shown to be highly intelligent (but lacks certain knowledge of the
world), and is usually seen snacking on melon bread.
Shana was originally voiced by Tabitha St. Germain for the franchise's first season, which was dubbed by Ocean Studios and was at the time licensed by Geneon USA. When FUNimation rescued the franchise years later, and continued on with the dub production, they could not afford to pay for the Vancouver voice actors and recast the whole show with in-house voices for further media. For the recap movie, Seasons 2-3, as well as the OVA, Shana has been voiced by Cherami Leigh.
