Assassin (Yamazaki Susumu)

(山崎烝), class name Assassin (アサシン), is an Assassin-class servant able to be summoned Fujinami Satoru in the Grand Conquest of Fate/Divine Order.

Identity
Assassin’s True Name is (山崎烝), the doctor, spymaster and inspector for the Shinsengumi. At times, he was also considered to be “The Most Loyal Shinsengumi Member”.

Yamazaki was born in 1833 to an acupuncturist father. He first joined the Shinsengumi at the tail end of 1864 and the Shinsengumi used his pharmacy as their headquarters before they moved to Nishihonganji. He was recognized for his talent in writing and military arts which was taught by his uncle and within a few months of joining the Shinsengumi, he was assigned as an investigator and spy for the group.

His job as an investigator was different to the captains of the Shinsengumi, as his job was to supervise the members of each unit, making sure that they’re in line and to conduct operations during official duties. It is also said that he had a good knowledge of Kyoto and Osaka, and often took his officers to Osaka as a guide. He was also well versed in the affairs of the rich merchants of Osaka, and through Yamazaki's help, the officers were able to raise funds for the troops, making him a valuable member of the Shinsengumi thanks to his vast network. Yamazaki also studied medicine under Matsumoto Ryōjun and became the doctor for the Shinsengumi as well, though those who heard it usually laughed at the statement of him being a doctor for the force.

The job of a spymaster for the Shinsengumi was to infiltrate the enemy to gather information, following the target, and extracting information. The inspector's duties include investigating illegal activities, gathering evidence and conducting investigations in order to punish them according to the local law. Yamazaki’s job was mostly behind the scenes but it was an important component as to why the Shinsengumi was able to exert its great power in maintaining public order.

Yamazaki was also seen as Kondō Isami’s most beloved. At the battle of Toba-Fushimi, Yamazaki joined the battle along with his comrades, it was also the last battle he fought as he died due to severe injuries. It is said that Kondō broke down during Yamazaki’s funeral and told Hijikata that "Yamazaki was a good man. He was happy to be sent off by so many people.”

Personality
Yamazaki is a rather mild-mannered man of few words, he rarely talks with anyone outside the Shinsengumi preferring to stay quiet or smoke cigarettes. Those who have talked to him see him as a calm and considerate man who’s willing to talk as long as they have something important that he can gain from them, though Yamazaki says that he dislikes talking much since he “doesn’t want other spies to find out important details about him”.

Though when around Shinsengumi members he would open up more of himself, especially towards his closest friend Kondō Isami. He’s more willing to share his emotions and thoughts with them due to his connections with them in life. Though in his own eyes, he does not hate having others in his life. Some part of him worries if she would one day lose his friends again, along with his former job as a spy it was part of his instinct to lay suspicion on new faces.

 * Presence Concealment: C

Because the Shinsengumi had used his pharmacy as their headquarters, Yamazaki’s pharmacy is considered to be his “workshop” and is able to be recreated wherever he goes.Though because the Shinsengumi moved their headquarters to Nishihonganji later on, the pharmacy is often forgotten about despite once being a gathering place for the Shinsengumi.
 * Territory Creation: B

Personal Skills
Yamazaki was known for his deep loyalty towards the Shinsengumi, even earning the title of “The Most Loyal Member of the Shinsengumi”. Because of his loyalty in life, he has earned this skill as a servant giving him a bonus to his strength for following orders. Though, this skill comes at the cost of Yamazaki being difficult to compromise with as he feels the need to complete the orders exactly as said or written.
 * Loyalty: A+

As the son of an acupuncturist and working as a doctor, he is able to use acupuncture in order to stop enemies from getting near him or his allies, though he very rarely uses these acupuncture needles due to the exact nature of the points he needs to hit in order to stun them
 * Acupuncture Expertise: D

Discerning Eye allows Yamazaki to identify a person’s weaknesses simply by observing them, though Yamazaki prefers to use the skill to identify the weaknesses of his allies and try to better them in those areas.

Enforcer of the Shinsengumi Laws is a special skill only owned by Yamazaki thanks to his unique position within the ranks of the force.
 * Enforcer of Shinsengumi Laws: EX

The skill itself does not mean that Yamazaki is above the Laws of the Shinsengumi; the laws still apply to him but, because of his position as an Inspector and supervisor to the captains of the Shinsengumi, Yamazaki is also tasked with enforcing it and making sure that no one breaks the law. Unlike Laws of the Shinsengumi however, Yamazaki does not take damage when he breaks a vow but still increases his strength in combat.
