Akuma's Charm

Smiling impishly at the boy's irony, the mass replies, "Yes master." The mass begins to drift away but stops, floating in midair. The boy looks up at the mass growing angry till it speaks again.
"Before I leave again master, I'd first like to know what your name is."
"Uhm... Jim Macken."
"What a bland name for someone as heavenly as you... And what shall you call me?"
The boy looked up at those defrosting spring clouds and sighed loudly.
"I'll call you Ciel Macken <cough>. You'll pose as my dead brother for the time being. Now go."
The mass begins to morph. In no time it dissipates, leaving a small boy with a willowy body, dark blue hair, porcelain skin, and fuchsia eyes. The demon bows, with a light smile on his pink lips.
"Yes, big brother."

He commands Ciel to try and break the man with his charm. It works, but Ciel gets attached. What will the contracted akuma do to be with the one he loves but follow the orders of his young master?
