Shakugan No Shana (FUNimation): Season 1 (Blu-ray)

From the studio behind Toradora! and ?kami-san and her Seven Companions comes the iconic series centered around the heated bond and supernatural battles of two friends from two very different worlds. Wielding a blazing sword, Shana is a fiery huntress whose sole purpose is to fight demon-like beings that consume human lives. To reduce the impact on the human realm, Shana turns the slain into shadows of their former selves. Once a flame that represents their remaining life goes out, they fade from existence. This should be Yuji's fate, but when he discovers he holds a special power that ignites a newfound strength in Shana, they join forces in her ongoing mission to maintain the balance between the ordinary world and the supernatural.
