Tanaka is a seasoned butler in the Phantomhive household, with a dignified and composed appearance that suits his status. Despite his elderly age, Tanaka maintains a refined air of professionalism, often seen wearing a formal black suit paired with white gloves and a monocle, which hints at his long years of service and experience. His gray hair and mustache give him an almost grandfatherly appearance, exuding an aura of respect and wisdom.

Although often depicted with a smaller and more compact frame in regular scenes, Tanaka’s true physical height and stature are sometimes emphasized during critical or intense moments. This shift in his portrayal suggests that while he may appear diminutive in everyday situations, he is far from fragile or insignificant. In fact, Tanaka is a capable and sharp character who has survived numerous challenges over his long years of service to the Phantomhive family.

Tanaka’s loyalty to the Phantomhive family is unquestionable, and his calm, measured manner serves as a steadying influence on the other staff members, as well as Ciel and Sebastian. He is often seen quietly observing his surroundings, particularly with a cup of tea in hand, which is a subtle reflection of his calm demeanor. Despite his outward gentleness, Tanaka’s extensive experience gives him a nuanced understanding of situations, and when required, he is able to act decisively.

While much of his role is behind the scenes, Tanaka’s importance cannot be overstated. He has served the Phantomhive family for many years, and his quiet wisdom and quiet strength make him a cornerstone of the household. He represents the understated, yet vital role of those who support the Phantomhives in their complex world of mystery, intrigue, and danger.

Tanaka’s personality reflects a blend of wisdom, unwavering loyalty, and quiet strength. As a butler to the Phantomhive family, his devotion to Ciel Phantomhive is apparent in all his actions. Having previously served Ciel’s late father, Vincent Phantomhive, Tanaka carries with him a deep sense of duty and responsibility toward the household. Although his physical capabilities have diminished due to the severe injuries he sustained during the Phantomhive Manor raid, Tanaka still possesses the composure and authority expected of a seasoned servant.

While he no longer performs tasks with the same frequency as he did in his prime, Tanaka remains an indispensable figure in the household. He has earned the trust of Ciel and Sebastian Michaelis, often acting as a dependable adviser and confidant. His wealth of experience allows him to offer invaluable guidance, particularly when it comes to navigating the challenges of running the Phantomhive estate. Despite his age and limited physical mobility, he performs his duties with the same efficiency as any younger servant, demonstrating his professionalism and steadfastness.

Tanaka’s calm, measured demeanor extends beyond his professional life. He holds Ciel’s well-being as a priority and is not hesitant to admonish him when he sees fit, particularly when Ciel exhibits signs of vulnerability or weakness. His sternness comes from a place of genuine concern for the young earl, and while he may appear strict, his actions are always aimed at ensuring Ciel’s success and safety as head of the household.

Despite his age, Tanaka is not to be underestimated. In his youth, he was a capable fighter, having mastered Baritsu, a British form of martial arts. This skill proves useful when he is called upon to protect Ciel or the Phantomhive family. He is still able to spring into action when necessary, as shown when he effortlessly subdued an intruder who attempted to harm Ciel. Tanaka is the epitome of a servant who remains an invaluable asset, offering strength, loyalty, and guidance at every turn.

Tanaka’s history is steeped in tragedy and loyalty, which shaped his unwavering commitment to the Phantomhive family. As a loyal servant to the Phantomhive household, Tanaka was present during the horrific night when Ciel’s family was murdered. He had served Vincent Phantomhive for many years, and when the manor was raided, he acted swiftly to warn Ciel of the danger. However, during this attempt to protect the young heir, Tanaka was attacked by an unseen assailant, who stabbed him from behind. This brutal assault left him severely injured, and he was the only member of the Phantomhive staff to survive the massacre.

Despite his grave wounds, Tanaka was treated at the Royal London Hospital, where he was cared for by Ciel’s aunt, Angelina Dalles. When Ciel and his new butler, Sebastian Michaelis, visited Tanaka, the elderly butler was astonished to see that Ciel had survived, considering the circumstances. It was during this visit that Tanaka entrusted Sebastian with the Phantomhive pocket watch, a symbolic heirloom passed down through generations of Phantomhive butlers. Tanaka’s passing of the watch signified not only the end of an era but also the beginning of Ciel’s new life as the head of the Phantomhive household. It was also a gesture of trust in Sebastian, acknowledging him as the one who would take over the mantle of butler for the young master.

Tanaka’s survival and his dedication to Ciel continued to play a significant role in the years that followed. Despite the traumatic events, he remained a steady and reliable figure in Ciel’s life, offering counsel and support, as well as the occasional reminder of the importance of maintaining strength and resolve in the face of adversity. His loyalty to Ciel, though deeply rooted in the past, remained steadfast, even in the wake of the family tragedy.
