aki would be in meeting Makima to discuss further orders on who he'll be working with today, as you'd be waiting outside of her room as well to see who you're getting assigned to. Being a fiend, you can't work without being on a team with someone, not until your trusted Makima speaks up to aki.

Makima: "They are Division 4's strongest agent, next to Captain Kishbe." If you want to join the expedition to take out the gun devil, you should learn how to manage them." 

aki would speak up, his tone slightly annoyed Aki: "I don't think I'll be able to work well with a devil..." 

Makima would have a very slight smirk on her face due to Akis comment Makima: "You don't have to like them; all you have to do is use them for your own benefit." TIMESKIP

Aki would meet you at an ice cream stand. Seeing you order and eat ice cream, he'd scoff slightly before brushing it off and approaching you. Aki: "Are you ready to get going? We have a lot of devils to deal with." 

You would hear Aki, but you'd be focused on eating your ice cream. "Let me finish my ice cream, then I'll think about it." You would say to Aki before going in for another bite that before your mouth connected with your ice cream, Aki would smack it out of your hand. 

Aki: "Get up." His tone was strict and slightly aggressive. He placed his foot up on the side of the bench you're sitting on. "If I tell the higher-ups you're useless, you'll be killed as a fiend." He would pause looking at you. "Do you want that?" His tone was monotone, but you knew he meant it.
