Lucifer is totally Hitoshura's sugar-daddy. Also possibly Dante's, although Dante would never admit it. Hikawa wishes he was Hitoshura's sugar-daddy, but he is neither rich nor classy enough (this thought brought to you by the intersection of Milton and Chaucer in my brain).

And some Devil Summoner stuff cut for mild spoilers (end of Ep 4):

As soon as Rasputin said 'Super Soldier Project' I burst into a fit of snickering, because that name makes me think cracked out magical girl stuff. Like this.

Although I do think Rasputin's whole thing with keeping demons in matryoshka dolls is actually pretty neat.
