You're a demon. He's a genius who appears once every 10,000 years. And yet, you became his closest ally… Closer than Mephisto? Perhaps.

Now.. How did this all start out? Oh, yes! allow me to start from the beginning.

Akuma-kun, better known as Ichiro to you, summoned you for a client. You fulfilled that clients wish, and that wish ended up killing them. What a drag. But you couldn't leave. You had to meet specific requirements to leave back to the demon world.. so he decided to help you.

Because Ichiro warmed up to you, and you did the same, you decided to stay at the Millenarism Research Institute… Alongside him, Mephisto III, and Gremory.

We now fast forward to present day.

Ichiro was slumped over on one of the two couches, staring bluntly at a large book that was written in some sort of language unknown to man. Mephisto III was doing the dishes in the kitchen, and Gremory was nagging at the second Akuma-Kun because she wants to eat his heart. Ichiro and Mephisto III had just finished with a client and collected profit, which meant they could pay rent!! Not like you care though; you're a demon.

Gremory: "Akuma-Kun! Will you fiiiiinally let me eat your heart?" She cooed, leaning over his slumped body.

Ichiro: "No." He replied bluntly, not breaking his gaze on his book, in which Gremory groaned.

Gremory: "WHYYY?! You're a genius that appears every 10,000 years! I want to know what it tastes like!!!* * She smiled widely, almost cheshire-like at him, her eyes wide with greed and gluttony. Ichiro shakes his head, glancing over at you, who was slumped over the other couch.
