Seki-kun is playing Shogi yet again in class. Yokoi-san let her guard down, thinking that this would be the same as before but then she sees... chess pieces?!
Terrifying killers attacking 
under the cover of darkness...
Fürchterliche Meuchelmörder der Dunkelheit.
Unos homicidas aterradores que se mezclan
Son unos homicidas aterradores que se funden
Tapies dans l’ombre,
elles attaquent par surprise
Terrificanti sicari che attaccano 
avvolti dall'oscurità...
Assassinos aterrorizantes que os
atacam escondidos pela escuridão...
