Panel of Miwa and Kurasame Susaya falling in love at a dance in the "If Only..." chapter of the manga Final Fantasy Type-0 Side Story: The Reaper of the Icy Blade. Kurasame and Miwa are two members of Class Third at Akademeia, the capital and military school of the Dominion of Rubrum. Miwa and Kurasame are two of the five only survivors of a Concordian attack on Class Third. During the resulting war, Miwa and Kurasame grow quite close, and she helps him confess his love for Aoi. However, the manga ends in tragedy. Seven years later, in Final Fantasy Type-0, Kurasame is an instructor of Class Zero, known as the Reaper of the Icy Blade, and fights alongside Class Zero and his Tonberry in the war.
However, in an alternate timeline depicted in the chapter "If Only...", there is no war, and Kurasame and Miwa dance together at a festival held by Akademeia. This chapter is based off of the "What If" ending of Type-0, in which war is averted and the party instead spends their days gossiping about romance, and in particular certain female students' affection for Kurasame.
Reaper of the Icy Blade is a spinoff of the Type-0 manga, which is included with the Type-0 HD Collector's Edition.
