It is located in Littledove Hachiman City (小鳩八幡市), Japan.

St. Pigeonation's Institute was founded in 2180 with the ideal of coexistance between birds and humans. The Ichijou Group was the main financial backer[3], although the majority of investors had ties to the Hawk Party[2].

Operation Hurtful[]

After Souma Isa learned about Nageki Fujishiro's debilitating condition, he invited the mourning dove to attend St. Pigeonation's Institute in 2183 under the pretense of giving him medical treatment. In reality, Doctor Isa actually wanted to study Nageki's condition as he had suspected it had something to do with the Heartful House incident in which humans were killed without receiving any bullet wounds. It is here where it was eventually discovered that Nageki hosts a peculiar virus that they've dubbed the Charon Virus. Through a series of tests, the researchers learned that the virus is deadly to humans but harmless to birdkind. Operation Hurtful was then conceived as a program to eradicate humankind by using the Charon Virus.

During Nageki's first summer there, the researchers took him deep underground in order to perform experiments on humans. Nageki became distressed after realizing that he harbored a virus that was to be used as a biological weapon and tried to destroy both himself and the medical center in order to stop Operation Hatoful. Isa managed to preserve a piece of Nageki's remains that still harbored the virus and put the project on hold until a suitable replacement host could be found. The building above the medical center was then closed off and abandoned.

The Human Representative[]

Although the school was founded by well-meaning birds, members of the Hawk Party began taking over the school until the Human Representative Program was conceived in an effort to strengthen the animosity between birds and humans. They wanted to choose a healthy human that would be used for both the program and Operation Hatoful and ended up selecting Hiyoko Tosaka for the position. She enrolled in 2187 along with her friend Ryouta Kawara.

The program outlines that should the human representative die while in the school, the campus would be sealed off and all birds within are to be given to the humans as prisoners 12 hours after the death of the human is confirmed.

It seems that the headmaster of the school is made aware of the program and so a control system was installed in the headmaster's office to allow the headmaster to escape the school should the situation ever arise.

School Year[]


The front of the school.

St. Pigeonation's Institute follows a semester system with the first term lasting from April to July and the second term lasting from September to December. Students have summer break from 20 July to 1 September and winter break from 23 December to 10 January.

Although not an official school-sanctioned event, students regularly celebrate Legumentine's every 3 February.

Sports Festival[]

The school's Sports Festival takes place on 21 May and is basically a mini-Olympics of sorts. Events include a 3-legged race and a marathon, although students are free to be cheerleaders or help out at the first aid tent.

Cultural Festival[]

The Cultural Festival, also known simply as the school festival, takes place on 25 September and is an event in which each classroom sets up booths and decorates rooms to advertise themselves to earn money for the school. Among the events are a maid cafe, a butler cafe, a haunted house, and a manga booth. The science club, supervised by Shuu Iwamine, also does something for the festival.

School Uniform[]

The school uniform consists of a greyish blue blazer with light blue stripes going down the sleeves. The St. Pigeonation's crest is sewn onto the breast pocket. A white button-up is also mandatory, as well as dark pants.

First-year students wear a green tie. Second-year students wear a blue tie. Third-year students wear an orange tie.

St. Pigeonation's students are required to wear school uniforms, however there is a lot of freedom for personalization. There is no mandatory shoe style. As Sakuya Le Bel Shirogane is a noble who was preassigned the student council president, his school uniform is unique and stands out from other students.

It's unknown what the school uniform would look like for female students.

  2. An "interdimensional tunnel" in the student council room warping students to the dump.
  3. A "monster book" curse on anyone who draws in a library book.
  4. A secret menu in the infirmary.
  5. A pool of blood that appears in the restroom near the staffroom when evening comes.
  6. A wild demon called "Teke Teke" appears on the field after school.
  7. On dark nights a black mass is held on the school grounds.


"Honestly, [the reason] why I gave it such a saintlike name is just because so many schools in shoujo manga and dating sims in Japan are so (I don’t know why though! Perhaps it sounds special and fancy somehow for us?) But maybe Pigeonation was a great pigeon who guided birdies to the promised land."
