History
According to legend the monk Anchin while returning to the Dojoji Temple after a long journey rested overnight at an inn. During his stay at the inn, the innkeeper's daughter , Kiyohime fell in love with Anchin, with the two becoming lovers and spending a passionate night together. Soon after there was talk of plans on getting married. However after a night Anchin remembering his priestly vows left to return to his temple.
Kiyohime awakening to find her lover had abandoned her pursued him her hatred turning her into a snake-dragon. She found him hidden inside the great temple bell, which the coiled herself around, seven-fold until the metal bent and crushed the monk in iron.
In modern day, Anchin's remains, a skull, were recovered thanks to the research of Professor Sakai. The Bureau for Paranormal Research and Defense had managed to recover the remains for the professor and were due to deliver them to him for a conference he was presenting at in Port Alegre, South America. Hellboy, Katherine Corrigan and Professor Trevor Bruttenholm were on a plane traveling there when their craft came under attack by a murder of crows causing their plane to crash, killing the pilots transporting them.
The survivors needing a satellite signal to ask for rescue found a magical mobile castle that belonged to Holy Roman Emperor Frederick II and contained a menagerie of mythological creatures. While investigating the castle, Hellboy and Bruttenholm get separated from Kate and trapped inside the castle. As they went deeper into the castle, Anchin's head began mumbling "not afraid" and "not hiding". It soon became evident the skull was being drawn to something in the castle where the found an observatory of the late emperor.
They came across a horde of monsters which Hellboy began fighting before coming face to face with a crimson knight, who they believed was Frederick II. However after Hellboy tore out the armor it was revealed to be the snake-dragon Kiyohime who had been captured by Frederick II centuries ago and now somehow usurped control of his castle.
Kiyohime had Hellboy in her coils when Hellboy demanded if she was the cause for their plane's crash. But the snake-dragon was perplexed at the accusation as it had nothing to do with her. Anchin skull turned out to be the culprit, having sensed his old lover in the area he drew the crows to attack the plane in order to reach Kiyohime. Furious at hearing the name of the man who betrayed her Kiyohime was about devour Hellboy, but the half-demon managed to grab Anchin's head and throw it in Kiyohime's maw where it caused her to explode. Kiyohime reverting to her human appearance was seen hold Anchin's head tenderly, the two lovers' spirits returning to human as they kiss.
