OVA
Description
Jack Renfield is a significant supporting character in the narrative, known for his remarkable past and his dignified, if occasionally mischievous, present demeanor. Standing an imposing six feet and six inches tall, he is an older man with long gray hair typically tied in a ponytail and a well-kept goatee. In his younger days, as seen in flashbacks, his hair was shorter and predominantly black with only a few silver streaks. His usual attire is a formal black three-piece suit with a black tie and white pocket square, befitting his butler-like nature.

His background is deeply shadowed by violence and military service. Jack served in the British Army during the First Afghan War, where his effectiveness earned him the nickname "Jack," referencing a pocketknife. He also worked as a combat instructor during his time in the military. It is his extraordinary skill in melee combat that led to him being infamously known as Jack the Ripper.

In terms of personality, Jack is nearly always courteous and well-mannered, presenting a calm and composed exterior. He often displays a humorous and cheeky side, finding amusement in teasing his comrades, particularly Sebastian Moran. Despite this lightheartedness, he is deeply dedicated to William James Moriarty and the group's revolutionary cause, becoming serious and unwavering when following orders. He also has a notably flirtatious and shameless streak, showing immediate interest in Irene Adler upon her joining the group and, even after learning that Bond identifies as a man, confidently making flirtatious advances.

Jack's role in the story is foundational to the abilities of the main protagonists. After a fire destroyed the Moriarty household, the young brothers William, Albert, and Louis were taken in by Lord Rockwell, where Jack was working as a butler following his military service. Knowing of his deadly past, the three brothers requested he teach them the art of killing. He thus became their combat instructor, responsible for training them in the assassination techniques they would later use in their schemes for societal reform.

His key relationships are defined by this mentorship and his subsequent service. He holds deep respect and loyalty for William, following his leadership without question. For Albert and Louis, he is a mentor figure, having instructed them alongside William from a young age. His dynamic with Sebastian Moran is more casual and teasing, though built on mutual respect as skilled operatives. He also maintains a playful and flirtatious rapport with Bond, the former Irene Adler.

Regarding his development, Jack transitions from a feared soldier and assassin known as "Jack the Ripper" to a composed butler and combat instructor for the Moriarty brothers, and finally to a trusted affiliate within their inner circle. While his combat skills remain formidable, his personal growth is shown in his contentment with a supporting role, though a lingering habit from his butler days leads him to subconsciously clean up after others or do laundry. His notable abilities are centered entirely on his peerless skill in melee combat, a prowess so legendary it earned him his fearsome moniker.
