Mika

The manager of Café LycoReco. Male. 48 years old. His birthday is July 13th. Blood type O. A former DA training instructor and a father figure to Chisato. He was also a former DA commander but was removed from the position following the radio tower incident 10 years ago. He also serves as an on-site commander, giving Chisato work instructions upon receiving communication from DA. He has a large build, with dark brown skin, long curly hair, a mustache, and glasses. He has a gentle personality. He uses a Lofstrand crutch for long-distance walking, but this is an act to prevent others from realizing his strength, as he can actually walk without it. At Café LycoReco, he is dedicated to making sweets, and his coffee is also exquisite.

He was once a partner with Yoshimatsu both personally and professionally and was entrusted with the young Chisato after her artificial heart transplant. When he reunited with Yoshimatsu after a long time, he was criticized for not utilizing Chisato's talent for killing. He struggles with the conflict between Yoshimatsu's expectations and Chisato's belief in helping others and adhering to a creed of "valuing life" by not killing.

In the final episode, he delivers the finishing blow to the severely injured Yoshimatsu, takes the artificial heart, disposes of the message card Yoshimatsu wrote for Chisato, and has Chisato undergo surgery without informing her of Yoshimatsu's death.
