"Ky" is the real name of Code K, an experiment consultant at the Black Lodge. He has been assigned the code name K and is responsible for the development of various medicines and weapons within the Black Lodge. In the Black Lodge, he creates a wide range of weapons and medications, including Code B's "Drain Crossbow" and body-strengthening concoctions. His intense interest complements his work as a scientist.

As a student, Code K was a legend in Furvale, graduating at the top of the list despite his lack of magical talent. But when he was unable to find employment after graduation, he started to feel outraged at society for failing to see his potential. In fact, he has a kind heart. For initiatives requiring live trials, he prefers to test them himself rather than seek subjects.

Except for subjects involving science and magic, Ky is a rather wishy-washy person and struggles with social interaction. He makes an intentional effort to portray himself as a villain after making up his mind, but his acting is so poor that he always comes across as a joke.

Since his lab is where he feels most comfortable and at ease, Code K spends most of his time there aside from working with Code B. However, unless you have a similar fascination in bizarre science and potions, it does not seem like an ideal place to spend your time at. He also prefers honey mustard-flavored potato chips and zero-calorie sodas, which he'll always be glad to receive.
