Trinity General School: A seemly religious school in Kivotos. Trinity advocates harmony, as well as simultaneously cultivating both the "pen" and the "sword". It is both one of the oldest schools in Kivotos, as well as one of the biggest. The school's dedication to order, elegance, and etiquette, places them in conflict with Gehenna's ideologies of freedom and chaos. Resultantly, the two schools have been locked in a fierce rivalry for some time, with periodic flare-ups of tensions.

Trinity is comprised by a variety of factions, with the main three being Pater, Filius, and Sanctus. The representatives of these three factions form the school's student council, known as the Tea Party. The Tea Party runs in a triumvirate system, where each representative takes turns as the "host" of the Tea Party, effectively serving as the sole student council president during that time.

The school's security is enforced primarily by the Justice Realization Committee (EN: "Justice Task Force"), who are able to field large numbers of troops. They are in turn supplemented by the Trinity Vigilante Crew, who volunteer to handle most incidents involving delinquents and other minor threats.

Remedial Knights: One of the clubs in Trinity whose members train to help other students with, in most cases, their general health. The appearance of its members is similar to a nurse (in training). They hold the record as Trinity's oldest club, having existed even during the pre-alliance days of the school. Unlike their Gehenna counterpart, the Emergency Medicine Club, the Knights Hospitaller have some authority in politics. However, much like the Emergency Medicine Club, their focus lies more on medical treatment, and is willing to defend and treat any just about patient, regardless of school or standing.

Other Club Members:

Asagao Hanae:

Introduction: A lively and cheerful freshwoman enrolled as a Knights Hospitaller for Order of the Relief at Trinity School.

She has a positive and lively personality, but tends to become overexcited when she finds a patient, usually making the situation worse. Despite being quite an eccentric character, strangely enough, patients who have received her care have all recovered right away no matter their illness.

Personality: Although a good girl at heart, she sometimes takes things a bit to the extreme when it comes to treating patients. In fact, she once brought a chainsaw thinking she needed to amputate Sensei for a simple scar they had.

Uniform: Hanae wears a pink jacket with a white medic armband on the left, with a standard uniform consisting of a black sailor dress with pink lines on the white collar, with a Trinity logo that can be seen on her skirt below.

She wears pink shoes with white soles and a nurse headdress. She also carries a rabbit plush, held by a strap.

The hat has two soft deer-like horns on the side.

Aomori Mine:

Introduction: Mine is a warrior in white, an angel in white who has a strong and honest personality but also has a radical side. The leader of both the Knights Hospitaller and the Johannes faction within Trinity. Although her clubmates view her with admiration, she has an infamous reputation for preemptively using violence to prevent individuals from harming others, birthing the phrase "Mine destroys and the knights heal", which seems to be roaring throughout Trinity...

Personality: Mine is headstrong and passionate in her desire to provide aid for others, viewing it as her sacred duty. However, she has a well-known reputation for being violent about it, not helped by her strong sense of justice. She is quick to reach conclusions, which are often erroneous and in turn create conflict with other clubs and their members. She has a hobby of collecting disused medical equipment such as medicine bottles.

Appearance: Mine has waist length, light blue hair. She has bangs and two braids on the front on each side, tied with pink ribbons, decorated with various medication/hospital themed hairpins, and accesories.

Other clubs:

Tea party: The Tea Party is the student council of Trinity General School. Unlike most other schools in Kivotos, the Tea Party is a triumvirate, with the three leaders being representatives of Trinity's great three factions. It is a great privilege to be invited to the Tea Party. Its leaders are: Misono Mika, a student who is playfull but hates gehenna. Kirifuji Nagisa: A traditional student who likes tea parties, this is the main leader. Yurizono Seia: A psychological student who can see into the future through her dreams, she has fox ears and a fox tail.

Sisterhood: The Sisterhood is a major faction within Trinity whose influence is on par with that of the Tea Party and the Knight Hospitaller. They wish for the happiness and well-being of everyone in Kivotos, but many of Trinity's student are suspicious of them. Being the successors of the infamous Justina Council of Saints, they hold their fair share of secrets; some of which may shed light on Trinity's unknown history...

Justice Task Force: Their job is basically to enforce discipline within the school as well as deal with any troublemakers looking to disturb the peace. Even though Tsurugi is the official leader, it falls to Hasumi to actually carry out those duties due to Tsurugi's... problematic personality.

Remedial Knights: Prior to the school's formation, the Remedial Knights were the center of a faction called the Johannes faction. Like the other pre-alliance factions, they fought against the other factions until the First Ecumenical Council, where it joined the Trinity alliance. As many of the clubs were succeeded by their descendants, such as with the Justina Council of Saints and the Sisterhood, or simply perhaps disbanded, the Remedial Knights eventually became the oldest club in Trinity. It helps alot of students with medical problems and such.

Library committee: As suggested by their name, this club manages the library in Trinity. Shimiko is the librarian, while Ui works in the old section of the library, deciphering ancient texts.

After School Sweets Club: Similar to the Gourmet Research Society, the After-School Sweets Club serve as a food related club focused around sweets.

Yoshimi leads the group, while Natsu is often the one, who provides extensive knowledge of sweets and personal philosophy. Airi and Kazusa endures her antics to look for the most delicious candy in all of Kivotos.

Trinity Vigilante Crew: The currently known information of this club is it exist to maintain peace around the Trinity district, usually keeping the district clear from thug activities. According to Suzumi, the club is not an official club and anyone can volunteer to join the crew regardless of their background. While there's no clearly defined hierarchy of the club, Suzumi is considered the influential person in the club. Reisa also a popular person related to the club.
