"Shakugan no Shana S feels like a proper title for this collection of OVAs, as the release feels like it could simply be called Shakugan no Shana Slice or Shakugan no Shana Sample. Viewers are treated to what could have been four standard episodes mixed into the standard Shana seasons, as we receive equal amount drama and mystery as well as romantic comedy and slice-of-life events. With the English voice cast hitting their stride with the Shana series, Shakugan no Shana S is a bundle of everything that makes Shana great. With the English voice cast hitting their stride and the finale on the way, the Shakugan no Shana S: OVA release couldn’t have done a better job reminding fans why they enjoy the series."
