A creepy, headless ghost resembling the legendary knight, the Dullahan, starts attacking students at Hazakura Academy. Apparently, the ghost is looking for its head. Kiyoshiro, for some reason, gets caught up in the middle of this chaos…
In my estimation, I'd say
it's a western European knight's helmet
وفق تخميني، يمكنني القول بأنّها
خوذة فارس أوروبّي غربيّ
Je dirais que c’est celui
d’un chevalier d’Europe de l’Ouest
Secondo la mia stima, dovrebbe essere
l'elmo di un cavaliere dell'Europa occidentale,
Pelo que eu estimei, é um 
elmo de cavaleiro europeu
Я бы сказал, что это шлем
западноевропейского рыцаря.
