A small country campus fellow who thrives on farms and blacksmiths. The people who lived there lived poorly but richly. However, the war of aggression was approaching the small country. Under the command of Queen Amelia, Amelia, the kingdom of struggle and magic, monopolized many sorcerers and continued to expand her territory with paranormal power.
Campus fellows will be destroyed if nothing is done. There, the lord, Bud Grace, goes on a tactic of rejuvenation. It was to gather the evil witches scattered all over the continent and oppose the kingdom Amelia.
At the same time, it is reported that the "Mirror Witch" was detained in Leve, the land of knights, which is the neighboring country of the Campus Fellow. It is said that the witch who seduced the king of Leve and was about to take the throne of the queen was uncovered on the day of the wedding and slaughtered the attendees.
The lord, Bud, travels to Leve with his followers to take over the character of the "Mirror Witch". Lolo was in the line. Known as the "black dog," he was a boy who was struck by all sorts of killing techniques and raised as a campus fellow assassin ...
A spectacular and vicious dark fantasy that no one has seen yet opens the curtain.
MTL of the description of volume 2: (https://www.shogakukan.co.jp/books/09453009)
The murder that takes place in the "ice castle" surrounded by silence.
Lolo escapes from Leve with "Mirror Witch" Teresalisa, and returns to the Campus Fellow with Delirium, who continues to sleep under the influence of magical power. However, the hometown that was fallen by the kingdom Amelia was overrun by bloodshed and destruction, and there was no shadow to see ...
Lolo and Teresalisa meet with those who have fled the castle in a hideout built in the castle town. Ninety-two people, including the Chancellor Brasserie, who is in charge of the absence of the lord Bud Grace, and Victoria, the deputy leader of the <Knights of the Iron Fire> and the wife of Heartland.
They decide to abandon their hiding place and head for the <Northern Country>. There is <Gio, a cove village> governed by the Snow King Horio, whom Bud formed an alliance with during his lifetime. It was from the expectation that it would help. And Lolo had another purpose to go to <Northern Country>. It is to have a "snow witch" who lives in an ice castle on your side.
At that time, the "Tinkle Cathedral", the headquarter of Lucy's religion in the royal capital of the kingdom Amelia, gathered nine people with the highest rank of magicians-the "Nine Apostles".
A full-scale dark fantasy "Witch and Hound" that attracted a great deal of attention at the same time as it was published due to its shocking development. The long-awaited sequel is finally here.
