After the death of her husband in S.1196, Irina dedicated her life to her family's company, the Reinford Group, in order to make it as succesful as possible. She hired the maid Sharon Kreuger to look after her daughter, Alisa, and the housework the following year.
In order to push the growth of the company to its limits, she crossed the boundaries of morality and forced her father, the then-chairman Gwyn Reinford, to resign. She officially succeeded him in S.1199. She then continued to built on her father's legacy by introducing a new self-supporting accounting system of the four divisions of the company to make them even more profitable.
