Shibusen is a school in Soul Eater which trains both Weapons and Weapon Meisters. It's main goal is to prevent the revival of the Kishin.
Shibusen is a school intended to train meisters and weapons for the purpose of preventing the revival of the Kishin. It was founded by Shinigami-sama (who is bound to the school), and is located in Death City, a city inside Nevada USA.
The founder of the school, Shinigami-sama was once a powerful entity who wreaked havoc across the world, but now he has repented for his ways and turned on his former pupil Kishin Asura and trapped him inside the school. He created the school to train students who could one day fight him if he were freed. Shinigami-sama has a very fun and upbeat attitude despite his dark past.
Shinigami-sama's personal death scythe and weapon of choice, he is also Maka's father. He serves no steady position at the school other than simply being Shinigami's assistant of sorts and a weapon when needed to be, but he does fill in from time to time as a substitute teacher.
A teacher at Shibusen, Franken Stein is a mad scientist and also a very strong fighter as well. He has a unique way of teaching as he views everything as an experiment. One of his first lessons is dissecting animals much to the shock of the students and helps to teach them about getting in tune with their spirits.
A teacher at Shibusen who focuses on covert ops, he had his body zombified to help with his powers and covert skills. He also has a close relationship with Black Star almost like an uncle or father figure.
Marie is a Death Scythe Shinigami placed in charge of Oceania, but later in the series she is forced to return and serves as something of an adviser to the students, especially the more troubled ones like Crona.
