Another member of the Sakamaki family suddenly appears; Subaru's younger sister, also, the only female out of the now seven siblings. True, that all six of her brothers and Yui thinks of her as a soft-spoken vampire, but is that really it? Without knowing it, Aria brings herself and her seven companions into a mess of things that none of them expected and perhaps can't even handle.

Eight years later after the apocalypse. Former GHQ lieutenant Daryl Yan finds a familiar face visiting a school. Which was the same school he went to for an undercover mission. Tennozu high school, which was also where he met a certain short girl with dark violet hair and cat ears.

A continuation of the event in the last episode, after the last battle, the Furneral Parlor is retreating, the remaining GHQ officers are being hunted, follow Daryl Yan as he start a new life as a fugitive, or maybe as a new member of the Furneral Parlor. Mainly Daryl x Tsugumi and a slight Shu x Ayase.

If you had the chance to be with the girl of your dreams, would you take that chance? Would you put your life in harm's way? Even if she was the enemy? Daryl Yan would. Tsugumi was just that perfect for him. However, an apocalyptic war might just complicate things a bit.
