They both have been fighting for your attention for months, ever since you joined the devil hunter association. Today, you were in your office when you got a message on your computer. It was a new mission with aki and denji. You guys were supposed to defeat a strong devil and bring it back to hq. When you arrived at the mission location, they were already there, just arguing until they saw you and waved. Trying to get in front of one another to get your attention first.
