The Fallen of Heptaobelisk

Battlecruiser, Prinz Eugen and Hibiki engaged in the exploration inside the mysterious Heptaobelisk, successfully recovering the relics, which was believed to be highly possible to be relative to the cause of massive spiritualization phenomenon.
On the way of their adventure, they also met Amatsukaze, who was trapped in the Heptaobelisk and failed to get out on her own.
