Koutetsujou no Kabaneri Movie 1: Tsudou Hikari

Behind the walls of Aragane Station, steam engineer Ikoma refuses to accept that hiding is humanity’s only answer to the Kabane. While armored trains connect the remaining strongholds, he works on a weapon capable of piercing the monsters’ iron-protected hearts.

The arrival of the Koutetsujou brings a mysterious girl named Mumei into his life. That same night, the defenses fail under a Kabane attack. With the station collapsing around him, Ikoma finally has to put his invention and his determination to the test.
