Yokai, ayakashi, spectres, demons, mononoke, and ghosts... Everything has order, and you must never go against the order. Kotoko's fourth solution is accepted by the users on the wiki site and Kuro is able to give the final blow to Steel Lady Nanase. Will that be enough to finish her off?! And what exactly was Rikka's motive?
That's why I have Kuro-senpai 
call me by my surname.
.لهذا جعلت كورو-سينباي يناديني باسم عائلتي
Kuro lass ich mich ja auch
mit Familiennamen ansprechen.
Por esa razón hice que Kuro
me llamase por mi apellido.
Por esa razón hice que Kuro
me llamase por mi apellido.
Kurô aussi m’appelle
par mon nom de famille.
mi faccio chiamare per cognome 
anche dal senpai Kuro.
Por isso eu peço para o Kuro
me chamar pelo sobrenome.
Поэтому-то Куро ко мне
 по фамилии обращается.
