A very care-free and imposing but kind man. Dr. Leskinen is both a respected doctor and a "big child" according to his assistant Maho. Despite his seemingly well-meaning nature, Leskinen secretly works for a shadowy organization called Strategic Focus. Much like SERN, they are seeking information on time-travel based on Dr. Nakabachi's thesis. This reveals a much darker side to Alexis, an uncaring and unscrupulous man who is willing to use his own people as human test subjects for his experiments.
