During a livestream on Niconico, which commemorated the first anniversary of the "Phantom of the Kill" smartphone game, game producer Jun Imaizumi announced six new ventures for the game. One of these projects is a 15-minute anime concept film directed by Naoyoshi Shiotani from Production I.G, who has previously directed popular animes like "Psycho-Pass" and "Blood-C: The Last Dark." "Phantom of the Kill" is a tactical drama RPG created by Fuji & Gumi Games, which features girls with weapon names such as "Masamune" who strive to recover their memories. Furthermore, players can gain access to new characters and weapons, and participate in turn-based battles in various dungeons.
