It was during the classroom visits, Alex was trying not to start laughing Rias's embarrassment. Her father and brother were very obviously filming her from the back of the room. Alex though didn't have to worry about his parents due to him doing everything he could, even using his Devils charm to cut contact with them.

Later during a break he was walking through the hallways when it looked as if there was a photoshoot. Alex recognized the subject being photographed, and walked forward. He watched her taking several poses for a few moments before Rias joined him and started face palming. Then Saji had appeared and started trying to control the situation for the student council. He then tried to reprimand the girl, but Alex walked forward and put his hand on Saji's shoulder, much to his distaste.

"For future reference, I would recommend looking into the identity of people before reprimanding them, right Serafall Leviathan?" At first Saji didn't care too much for what Alex was going to say, but when he heard the later part, he became quite pale. The girl, a Maou, one of the ones ruling the Devils, looked at Alex with shining eyes. She was curious about this new dragon devil who identified her with a glance, but before she could, Saji freaked.

"Th-th-THE MAOU?!" He was in shock that this was the older sister of the woman he loved. Just as he shouted out, Sona herself appeared with Rias's father, brother, and Grayfia in tow. Her eyes widened at her sister, then Serafall shouted with glee,

"FOUND YOU SONA! Why didn't you welcome your big sister? I was so lonely when my Sona didn't show up, I almost wanted to destroy heaven!" She then flew at Sona only to be dodged by her. Sona was quite red faced and almost had tears in her eyes as she said,

"This is the area I watch over, please have a care of how you act here otherwise it will hurt my image. Please change that outfit and watch your behavior!" Serafall was devastated by Sona's words and declared,

"If Sona doesn't like big sis, then I'll be sad and have to take out my feelings on the Angels and fallen angels!" At that moment Sona looked as if she wanted to be anywhere else, so Alex decided that this might be a chance. He quickly moved to be beside Sona, and whisked her into a princess carry, and said,

"This princess doesn't seem to want to be here, so this dragon will perform his signature move and kidnap the princess." And with that Alex ran off with the brilliantly red Sona and left the dazed Serafall behind. She then registered what happened and started grumbling to herself,

"This pesky dragon ruined my yuri yuri moment with my Sona, should I track him down and destroy him?" As her words were heard throughout the group several people tried to talk her down to no avail, until she found a slip of paper in her skirt that she didn't notice. Once she read the message she called down a bit, and looked towards where Alex disappeared with her sister once again, except she had a weird glint in her eye.

Meanwhile Alex was drawing quite the looks as he went through the halls while having the president of the school in a princess carry. Sona was still completely red faced and cursing him to put her down. He finally did so when they were alone and quite a ways away from the others.

"W-w-why did you do that?! Imagine what people might think of me after this! What about big sis? She's going to kill you now you know!" Alex then chuckled lightly, and said,

"What's this, is the kidnapped princess worrying about the dragon that stole her?" When she heard his words Sona once again turned completely red and shouted,

"OF COURSE NOT! But I don't want to hear it from Rias when my sister kills her boyfriend, and by the way, why are you acting like this when you're dating her? It's like you're a completely different person compared to the last two years." Alex then laughed again, and said

"Rias knows I want to be surrounded by several women and has started to accept it. I spent the last two years purposely laying low so that I didn't get picked up by those with nasty intentions. And about your sister I already did something to pacify her so don't worry, you should worry about yourself right now." As he talked he was getting closer, Sona who just noticed this tried to regain her composure and started trying to act "cool" again.

"If you take another step closer, i won't hold back even against you." Though she started to regain her composure, Alex still heard a bit of shakiness in her voice. He stopped taking steps, and stood still. But he was so close now that they could feel each other's body heat and he could tell her heart was racing. Before she could react he quickly stole a peck on her cheek, and ran off shouting,

"Next time, I won't give back the one I "kidnap"." Sona just stood there with a hand on her cheek as if she couldn't figure out what just happened, until a moment later when her face turned the reddest it had been until now.

Alex was satisfied that he left a deep enough impression on both of the girls for the future. He then continued back to his class, where he noticed that both Rias and her brother were gone. He then remembered that he was about to meet the trap that was terrifying for several reasons.
