Wielding two handheld, 36-inch rapiers, Harlequin is effective while engaged in short range combat. Besides utilizing the rapiers as a cutting armament, it also contains an internal heat source that he has the authority to manipulate. Whether it be burning the blades to a scalding temperature during battle to make for smoldering lacerations or for medical purposes: scorching open wounds in order to close them, its fire element is useful in various situations. However, using this aspect of the rapiers causes large energy drainage depending on duration of use. For example, 15 minutes worth of heat can cause Takeshi to feel groggy and light headed afterwards while 30 minutes may bring about nausea and a pounding headache. Overheating the blade can also result in breakage of the weapon and an extended time for regeneration. This poses as a disadvantage during battle since he may be unable to defend himself with either rapier whichever becomes unusable if not both and make for a vulnerability. Having taken casual kickboxing lessons since he turned 20 (4 years of experience) has also granted Takeshi with valuable speed and agility.

Prior to the booming age of the DgtWld, Takeshi was your average teenage male brewing up trouble with his group of friends, flirting with girls, and dealing with school. He lived in a household made up of a father, a younger sister, and a cat. All in all, his life was pretty simple and he was satisfied with it. As technology continued to push forward as a dominant figure nationwide, its advances eventually merged with the Gvn becoming a major part of not only daily life, but becoming life itself. 2016, the year MChips were compulsory the moment a baby was born into the world. Anyone who did not have one was required to attain one immediately; there was no other way to live so rebelling was impractical. Upon obtaining an MChip (at 18) and utilizing its capabilities to go anywhere and do anything at his will, reality started to dull and Takeshi no longer felt fulfilled with the real world like he used to. His father was laid off from work as a police officer since crime rates were plummeting monthly and supporting a family of three was put onto his shoulders although the hardship was lessened by the fact that because of the modern electronics, the economy was thriving and goods were extremely affordable. Juggling a job in a vet clinic while also struggling with college, Takeshi jumped at the chance to become a Corrector the moment he was offered the opportunity. Paying for bills, education, and keeping food on the table can stack up rather quick when you're a 20 year old with relatives to take care of. His father sunk himself into addiction with the DgtWld and Takeshi rarely ever saw the elderly man get out of bed to do anything; often, Takeshi would have to barge in and force feed his father just to keep the guy from dying of starvation. A year before graduation (2021 and 23 years old), his dad passed away mysteriously in his bed while roaming the Digital World. The investigation was short and they told him the death resulted from a stroke and had nothing to do with the program. Did he believe it? No, but Takeshi wasn't going to risk his relationship with the Gvn to pry into the issue. Currently, he still inhabits the quaint two bedroom home his father left for his sister (Ume) and himself along with their feline (Yoi). His day-to-day routine consists of mothering his younger sibling and cat, heading out to vet school, completing Corrector tasks, and laboring night-shift at the vet clinic. As for his hobbies and social life, he manages to find time to spend with other Correctors around Tokyo, takes occasional off-days to enjoy the DgtWld and all the entertainment it provides as well as physically going out into the city. Kickboxing sessions take place at least once a week to keep himself in shape for both Corrector and health related purposes.
