Mission Doubleshot
However, they only carried out missions as ordered by Chelsea and didn't become too involved with each other.
Cylo was an individualist; he preferred to do everything alone. There were no burdens, allowing him to focus on himself. So, to be honest, he felt annoyed by Maki's presence on this mission. But what could he do? These were orders from his sister, so he had to obey.
For your information, Chelsea was a hacker who offered black market services to individuals in the underworld who needed them. Anything, including murder, theft, manipulation of events, and others. And of course, all of that would be carried out by Cylo as the executor.
