It was after school and Alex was sitting at a cafe with Rias Gremory. As he looked at her he noticed that though she was still immature looking compared to the series, she still had the appearance of high society as she ate. The two ate for a while, before she finally talked about why she asked him out.

"I'm restarting the Occult Research Club at school, would you like to join?"

'That's what it is!' Alex thought to himself. He guessed that she noticed the fight earlier, and wants to see if he would make a good servant. As he got hit with the bat several times yet isn't noticeably injured, and fought with twenty people with ease she probably thinks he'd make a good rook. Alex smiled slyly, and replied,

"I'm not really looking into any clubs at the moment, though I do appreciate the offer. I want to keep my afternoons open." As it was the time that he usually trained he was speaking the truth, but there was also that fact that besides already being a devil, he wasn't here to become someone else's servant. Rias looked reluctant for a moment, before turning on her Devils charm and saying,

"I would really like it if you reconsidered, it's only me and Akeno there right now." As Alex was also a devil that possessed the charm, he was completely unaffected.

"Though I'm not against the idea of spending more time with you, as I said I would have to decline your offer." Rias was shocked as she noticed that her charm didn't work at all. She used her Devils senses to see what made Alex so unique, but couldn't sense anything. The reason for this was that Ddraig was actively trying to conceal Alex's powers. A high class devil was no match for a heavenly dragon, even a sealed one. She eventually decided that he was simply descended from a hero or something, and wanted him even more.

"You said something about spending time together, what did you have in mind?" If he wouldn't join her club, then she needed to keep an eye on him someway. Alex smiled, as he figured he knew what she was thinking. He then said without any shame,

"I would like you to become my girlfriend." For the second time she was shocked, but for the first time she showed it. She then weighed her options, she was technically engaged, but never agreed to it. Her main concern was Raiser attacking the human that dared laid hands on "his" woman, as she didn't like the idea of others being hurt due to her whims. She eventually decided that as long as things didn't get too far, it wouldn't be too risky, as she was trying to recruit a new member for her peerage.

"Let's go on an few dates first, and I'll consider becoming your girlfriend." She said as she didn't want to seem desperate or easy. Alex smiled as his idea worked, but to Rias it just seemed as if he was happy to be dating her as he had tried approach her a few times already. They spent the next hour or so talking and getting to know each other. After they finished talking, they gave each other their numbers and left. As Rias had to go back to the school, Alex decided to act the role of boyfriend and escorted her back.

After escorting her back to the old school building, he then started walking to his training area. He kept his senses alert for any signs of being followed as he was sure Rias would be trying to keep an eye on him. Sensing nothing he returned to the same place he trained everyday, and created the magic circles to increase gravity. He then activated his dragons wings and was trying to keep flying while gravity tried to force him down.

At the same time Rias was sitting in her new club room in deep thought. Akeno brought her some tea, and noticed from her demeanor that the negotiations didn't seem to go well.

"So we don't have a new member? I thought he walked you all the way back?" Rias only smiled bitterly, and replied,

"Nope, it seems as if I actually have a boyfriend now. Devils are considered the ultimate conman, but I think this time I was the one conned." Akeno was shocked at her friends words, as she also knew about the engagement. But she also considered about how this man might surprise her like he did earlier. She had heard the rumors and judged them to be accurate based on his looks, but the only reason she cared was because he kept trying to approach her master. It wasn't until today that she realized that she was hasty in her opinion, and she couldn't forgiven herself for that most, after all she herself had that "filthy" part of her. She then said,

"Are you at least going to try and keep and eye on him?" Rias nodded and said,

"That's part of why I accepted. He's not normal, I even tried to use my charm and he just shrugged it off like it was nothing. Even if I use my familiar to spy on him I doubt it'll work for long. The best plan I have at the moment is to keep an eye on him and hope I don't chase him off to someone else." Akeno nodded, and continued preparing the tea.
