Izumi Akazawa is the main villainess in the manga and anime series Another.
Against Sora's Team
After Kouichi and Mei escaped the Yomiyama North Middle School with Sora while Izumi was hunting Mei down, she encountered Xemnas, who forged a weapon calling it, The Scythe of Tormant. By Xemnas understanding her thirst to hunt down and kill the person she wants to most, Izumi accepted the scythe and the two of them escaped the building that was crumbling down. She later was trained by Marluxia, who taught her the ways of the scythe and combat before his defeat by Abbey Bominable. Izumi then became much more stronger than before as she seeks revenge and swears to become powerful than Mei, also vowing that she will end kill next time.
