Isaac is long lasting in many ways. Due to his earlier trainings he is slow to be excited and even slower (or near impossible) to experience climax. While people may find this frustrating as he's hard to please, this trait allows him to perform his job perfectly without much distraction from his own body reactions.
Having been a trainer himself for several years Isaac knows what he's doing and knows how to deal with many kinds of people. He is quick to find his partner's pleasure spots and is not afraid to exploit them.
If asked for, anything provided to him can be used as a tool for pleasure. He himself carries a great variety of toys to play around with, and he is constantly collecting more just in case.

Motherly gentleman: Isaac is quite a gentleman, partly due to his British background. He is calm, passively charming, and soft-spoken. His language are often very formal and polite, and he has a habit of giving everyone formality titles in front of their names. As one gets to know about him, Isaac tends to act more feminine under his graceful covers. He is no doubt a mother hen, easily startled and a worrywart. To people close to him he gets very naggy at times, often lecturing others on what he believes to be in good health. Isaac sees other people's wellbeing above his own, and is more than willing to give without expecting anything in return.
Submissively dominant: Isaac likes to be in control of his life and perhaps even others. While he understands that sometimes things might not get his way, he gets agitated at those times easily and tends to panic whenever it happens. He is never one to take initiatives in anything, often making friendly suggestions on what should be done and leaving the final decision to others. In a way, he is quite dominant, simply because he is too nice, often leaving whoever with ill-intention feeling extremely guilty. He also seems to possess a calming aura for people around him---even those with the fiercest temper would be forced to act tame around him.
Big child: Due to his lack of a proper childhood, Isaac is, according to his own words, reliving the life of a child now. He is very curious and naive about his surroundings, and tends to find everything new and exciting. A fan of fantasy and fairy tales, Isaac would rather sit with the kids and watch a disney movie than engaging in an intelligent conversation among people of similar age. Isaac also gets easily expressive when it comes to things he likes, his eyes would literally be filled with sparkles, ones that could only be found in a curious child.
Proud Servant: Isaac is proud in what he does, and that is to please other people. He is very much humble, but at the same time, he is confident in his works as a servant. Stubbornly persistent and determined when it comes to pleasing others, Isaac feels awkward when others try to please him. To him, happiness comes from seeing others happy, not from self-satisfaction. Probably due to the fact that he's still very much a man despite his slender looks, Isaac is not comfortable accepting gifts from others, especially from strangers---as he does not like being courted and treated as a delicate lady.
Stagnantly flexible : Simply put, Isaac does not deal with changes in environment well. Added to that, he is very sensitive to changes, making it even more difficult. It would take him days or even weeks to readjust to a new schedule, which often leaves him tired and grumpy. On the contrary, he is very adept at dealing with different people and their situations. Having dealt with all kinds of clients in the past, he knows how to tackle problems from different angles, and will not hesitant to role-play his colder personality to get what he wanted.
Isaac grew up in an environment where sex was a common occurrence. His mother was a S&M trainer while his father was one of her client. As a child the boy was overly exposed to a wide variety of acts her mother performed, as she wanted him to follow her career in the future, to the point that he found normal sex boring and certainly not enough to stimulate him. In a way, he was put through a desensitization training by his mother ever since childhood. Despite being looked down upon by the normal society, his mother held the firm belief that S&M a form of art just like dancing or singing. She had successfully drilled this belief into her son, who in return never loathed the acts despite various attempts from his earlier friends to try to pull him away from it. Eventually Isaac stopped talking about his interest and his goal of succeeding his mother, and continued to learn without being vocal about it.
When Isaac reached adult age, his mother forced him out of the house, challenging him to start a career as a S&M trainer by himself. The young man wandered city to city for a while before finally settling down in the suburbs of a city flourished with young people full of bold and new ideas. There, he opened an underground shop and began to offer to those who desired his "service" at night while working as a waiter in a high class restaurant in the morning.
The shop was small, but received positive attention from his clients, who returned many times for the pleasure he could bring. Isaac took pride in his shop, but soon realized that some of his clients became too attached to the place--or himself. One client in particular distressed him, as she confessed her love for him over and over. Isaac, inexperienced with actual romantic feelings, was hesitant to reject her advances. His lack of definite reply eventually gave the woman the wrong idea, who soon claimed Isaac as her lover and leashed out on the rest of his clients. During one incident, the woman attacked a client who she believed to have been sleeping with Isaac. When Isaac defended the client, she suffered a mental breakdown and destroyed Isaac's shop. What was worse was that the incident drew attention of the press, which attracted a lot of criticisms. The normal society demanded the complete closure of the shop, and Isaac was forced to leave the city, searching for his next destination.
At some point, he came across Lanua Peccati, and decided to stay there temporarily and learn more about his job before advancing again.
