Yuuji Kazami

Yuuji Kazami is a the main character of the visual novels and later anime Grisaia no Kajitsu, Grisaia no Meikyuu, and Grisaia no Rakuen. Yuuji was born some time in the late 1990s to an ordinary Japanese couple. During his childhood, Yuuji was constantly overshadowed by his highly intelligent child prodigy older sister, Kazuki, who was a professional artist even in her childhood. Yuuji's parents doted on his sister, while neglecting Yuuji. The only member of his family who showed Yuuji kindness was Kazuki herself.

Yuuji's already troubled life turned for the worst when Kazuki was killed in a bus accident, and Yuuji's father descended into alcoholism. During this period, Yuuji and his mother were regularly abused by his father, forcing them to flee from their home. After leaving, Yuuji felt some small degree of peace, and his mother even started showing him the affection she never had in his early childhood. All this ended, however, when Yuuji's father found them and attempted to rape his mother. Yuuji struck his father of the head with a glass bottle, killing him. Shortly afterwards, his mother committed suicide.

Yuuji was taken in by a former buyer of his sister's work, a foreigner named Heath Oslo. Heath initially forced Yuuji to dress as his sister, wearing a wig and girl's clothing, but never actually sexually assaulted him. One of Heath's associates, however, was attempted to do so, forcing Yuuji to kill for the second time.

When Yuuji proved for the second time that he could kill a grown man at only about ten years of age, Heath Oslo showed a darker side, and sent Yuuji off the foreign school, actually a terrorist training camp, where Yuuji was trained alongside other kidnapped children as a child soldier. At the camp, Yuuji proved himself to have a natural talent for marksmanship. Here, Yuuji befriended a fellow child soldier, a girl known as "Marlin". For his "final exam" at the training camp, Olso forced "Marlin" and Yuuji to fight to the death. Yuuji, however, refused to kill his friend, only to be brutally beaten by her, but survived.

Oslo allowed Yuuji to attempt a second test, to assassinate an important member of the International Criminal Court in Canada. Yuuji succeeded, and later assassinated several other people in countries including the United States, France, and Japan during his teenage years. Yuuji was rescued from Olso's terrorist group when a joint US-JSDF force attacks the mansion where Yuuji was imprisoned.

Yuuji was taken in by an expert sniper in a Japanese-American joint-counter terror unit CIRS, a woman named Asako Kusakabe, who, recognizing Yuuji's talents, trained him further in marksmanship, close combat, and other military skills. At the same time, Yuuji came to know Kusakabe as "Master", and became close to her. Yuuji also became close to Asako's friend and colleague, Julia Bardera, a half-Japanese, half-German agent, who later became Yuuji's handler at the agency. After Asako declines in health, Yuuji falsifies his age, with Julia's (reluctant) help, and joins the military in his late teens, and is tranferred to train with the US Marines, where he once again proves himself an expert shot.

In spite of his young age, Yuuji quickly proved to be an expert sniper and a deadly close combatant, earning him to the serial number "9029", which is reserved for the deadliest agent in the unit. After the unit aided Canadian authorities in stopping a terrorist plot at the Vancouver International Airport, Yuuji, now 17, is placed on leave, where he states that the one thing he wishes to do is attempt to live a normal life.

Towards this end, Yuuji is enrolled in at Mihama Academy, a boarding school for a year, while remaining on call in case of emergency. At the academy, Yuuji quickly discovers it is no ordinary school, a fact first hinted at when he discovers that he has only five classmates, all girls: Amane Suou, Yumiko Sakaki, Michiru Matsushima, Irisu Makina, and Sachi Komine. Yuuji discovers the school was originally used as a "dumping ground" for a Yumiko, who was considered a "failure as an heir" by her rich father, and the other six were also placed there as they were considered to be "problem children" or "psychologically troubled". During his time their, Yuuji befriends all five girls, and helps them overcome their past traumas, and even rescues them from a sociopathic hostage taker. Yuuji become intimate with Amane during this period.

Shortly afterwards, Yuuji is returned to duty when Heath Oslo returned to Japan, first being sighted attacking a Japanese Coast Guard vessel with a rocket launcher. Oslo sends a clone of Yuuji to attack a foreign embassy in Tokyo, framing him for the attack. Oslo also places nuclear weapons in Tokyo, threatening to destroy the city if both Yuuji and the advanced supercomputer Thanatos, are handed over to him. Yuuji is imprisoned by the Japanese government, but transferred in a convoy that is attacked by Oslo. Olso's plans, however, are foiled by Thanatos, who its is revealed is actually Yuuji's sister, Kazuki, who was in fact still alive an interfaced with the computer, as well as Yuuji's friends from Mihama academy, and his old buddies from his days with the Marine Corps. Against all odds, this ragtag band escape with Yuuji and, as well as rescuing Kazuki.

Unfortunately, it is discovered Oslo rigged Yuuji with a nuclear weapons in a bracelet. After Yuuji's rescue, the JSDF disarm the two nukes in Tokyo, and Yuuji goes to deal with Oslo alone on his base of operations, an aircraft carrier belonging to Oslo's PMC, the Tartaros. Yuuji eliminates many of Oslo's guards on the Tartaros, and fights a duel against his clone, product of Oslo's super-soldier program- the original reason Yuuji and the other child soldiers were kidnapped was to create cloned super soldiers. After eliminating the clone, Yuuji faces Oslo himself, who attacks Yuuji with a katana that originally belonged to Asako, quickly proving to be a skilled swordsman. Yuuji fights him armed only with a combat knife, but the knife is destroyed and Yuuji is impaled on Olso's sword. In spite of this, Yuuji manages to grab a pen from Oslo's desk and stabs it into the back of his neck, killing him instantly. Yuuji manages to remove the nuclear bracelet and escape the carrier before the bomb destroys the ship. Two years later, Yuuji is reunited with his friends and sister, who escaped to an island in the Pacific.
