Shigeki Suwa

Shigeki Suwa (諏訪重毅) the main antagonist in the anime series, Buddy Daddies.

Overview
Shigeki is Rei's father and the boss of the organization. He has instilled in young Rei the skills and ideas of an assassin. He will show no mercy to anyone, even family members, in order to unite the organization.

Appearance
Shigeki is a middle aged man with hair in segments both white and brown. He is always seen donning a formal greyish suit.

Personality
Shigeki is a cruel, cold-hearted man, with a no-nonsense rigid business demeanour. An assassin thorough and through, Shigeki thinks very little about murdering others, no matter who they are, and cares little to nothing about colateral damage or hurting innocents so long as his business stands to benefit. Heartless and devoid of compassion or any warm feelings, Shigeki's number one concern is the estability and success of the organization and will do anything to ensure its survival.

His focus into his business is such that he raised Rei for the sole purpose of breeding a successor to continue the foul family legacy. Even during his childhood, Shigeki showed no affection towards his own son, cruelly insisting that he is not his "father" but rather his "boss", neglecting and abusing him throughout all his life, even having Rei's dog murdered solely to harden Rei into a cold-hearted assassin.

Shigeki thinks little of personal bonds, insisting that anything outside concern for the organization to be a waste of time, and useless attachment, or even a detriment. Completely unforgiving of what he perceives as treason, he doesn't tolerate when the members of his group start building relationships or connections outside the group, believing that to be reason enough to warrant murder of civilians or even members whom he believes as disloyal. Shigeki ordered the murder of Rei's mentor, precisely because he had been thinking of eloping with a woman, and even had her killed as punishment.

Shigeki is also shown to be perceive himself as a man of status and high class, deriding Kazuki as a "peasant" or praising Rei for showing better formal etiquette.

Background
He first appears in Rei's dream about a childhood memory. In the memory, he has shot a dog, then scolds Rei when he calls him "Dad" and reminds him that he is his boss.

On Rei's birthday, Shigeki calls him back home and informs him that it was time for Rei to return and learn to lead the organization. When Rei asks for more time, he gives him the mission to take care of Satoru Kaji.

Rei Suwa
Despite being his father, Shigeki does not allow Rei to call him "Dad", only "Boss". To him, Rei only exists to carry on the family's business and thus, trains him as such. He threatens Rei about his "pointless ties" when Rei shows reluctance to return.Nevertheless, when Rei eventually confronted him, refused to inherit the family business and made himself useless by shooting himself in the arm, Shigeki chose not to kill his son and let him go to his new family.

Trivia

 * According to one of the animators, Shigeki could give Miri Unasaka her first randoseru, which hints that one day he will try to establish a relationship with his son.
