Daemon

is the younger brother of Ada.

Background
Daemon and his sister were equipped with Shinobi-Ware by Amado in his hopes of bringing down Isshiki Ōtsutsuki's host Jigen. After learning that Daemon and his sister are among the cyborgs with the capabilities to defeat him, Isshiki ordered their destruction. Boro, who had his heart captured by Ada, had secretly hid the siblings and the other cyborgs away at one of his hidden establishments.

Post-Kawaki Arc
After Ada had awoken and formed a partnership with Code, she orders Bug to awaken Daemon. Daemon quickly jumps out of his stasis pod to ride Code's back, questioning if he is his sister's "new man". When Boro's guards learn of Code's intrusion, they attack the cyborgs, only for Daemon to use his ability to reflect their attacks back them.
