The following morning, as Sona and her Queen headed to school, they met Irina and Xenovia, the church duo. Sona didn't know the purpose of the church representatives, but she felt it wouldn't be a simple matter since they were carrying a Holy Sword.
After school, Issei was preparing to head home with Asia, but he was called in by Sona Sitri. Issei didn't know what it was about, but he didn't mind helping out. He found an empty classroom nearby and used his portal to send Asia home for the day.
Issei then made his way to the StuCo room. There he was met with Sona, who was waiting for him patiently. She asked Issei to take a seat, and Tsubaki poured tea for him to drink.
"So? What is it you need me for?" Issei asked. He knows that Sona is the type of person that would take care of any problem heading her way. "If you're asking for my help, it couldn't be a simple matter".
"That's right, it's not," Sona said. She sighed at the situation at hand. "This morning, two people from the church contacted me. They told me that they wanted to speak to Rias. I don't know what they wanted, but I accepted their request. I need someone to mediate the meeting to ensure that a blood bath doesn't happen. I know no one other than you to do so".
"Hmm…When is this taking place?" Issei asked. He didn't mind helping, but he would have to decline if it was on a Saturday. "I can accept anytime, but this Saturday".
"That's not a problem since the talk should be tomorrow," Sona said. She then leaned onto her table with her elbow and chin on her hand. "I'm hoping nothing bad comes about in the conversation with Rias and the church representative".
"No, problem, I can do so tomorrow," Issei said. He had no plans until Saturday. So, this is a great opportunity to kill time. "I'll be there. Is there something else you need from me?".
"It's my sister. She told me she would be in town," Sona said. She sighed. Her sister could be a troublemaker. "I was hoping you could maybe show her around? She'll be here on Friday".
"Oh, you don't have to worry about Sera," Issei said. He did have plans with her on Saturday. "The plans I had for Saturday was with her. We're heading to a magical girl convention".
Issei felt a Demonic Power in the vents of the StuCo room. This Demonic signature was something he was all too familiar with. Issei smiled and was planning on fulfilling a promise long ago.
"I don't get it," Sona said. She was confused about Issei's personality. "You're this smart and powerful guy, but you're interested in magical girls. It doesn't make sense".
"Hey! Don't go dissing magical girls. Besides, can't a guy have some guilty pleasure?" Issei said. He then thought of something. Sona would look good in a magical girl outfit. "By the way, you look good in the magical girl outfit you're wearing".
Sona looked confused at what Issei said. She wasn't wearing a magical girl outfit. But the moment she looked at her outfit, she was indeed wearing a magical girl outfit. Sona blushed hard. She was about to scold Issei, but he was gone.
"Hyoudou Issei!" Sona shouted. She was so embarrassed for wearing a magical girl outfit in front of her Peerage members. "I'll pay you back for this!".
If Sona wasn't shouting, she would have heard camera clicks in the ventilation system.
However, all Sona and the rest of her Peerage heard was Issei's laughter. Then suddenly, a rune around Sona appeared. She didn't know what it was, but she knew it was Issei's doing. Sona asked her Peerage to leave the room for a moment as she had to change her clothes.
While changing, she admired the magical girl outfit's elegant look. But she didn't want to be seen wearing it no matter how much it enhanced her natural beauty. She took it off and put on a new pair of school uniforms. Only for it to transform into another magical girl outfit. She screamed.
"I've never heard Sona-Kaichou scream like this before," Reya said. She was afraid to enter the StuCo room. "She sounds ready to kill".
"It seems like Hyoudou Issei has the talent for bringing out the other side of a person," Tsubaki said. She was a bit regretful that she could never bring this side of Sona out. Although Sona might look angry, Tsubaki knew Sona wasn't. She knew that Sona might even be admiring herself in the mirror as she spoke to Reya. "It's quite refreshing to see her like this".
"Really?! I think it's scary!" Reya said. She didn't want to come anywhere near Sona with the way she was at the moment. "She sounded like a banshee earlier".
Sona then opened the StuCo room door. Everyone saw that she was wearing a different type of magical girl outfit. If the outfit made her look elegant and gorgeous earlier, this new one made her look like a seductress. Saji saw Sona, and he fainted.
"Where is he?!" Sona said. She was going to kill Issei. "I'm going to make him pay! No matter how many times I change, it turns into a magical girl outfit!".
They had no answer to Sona's question as they didn't know where Issei had gone.
As for Issei, he was with Serafall, who arrived early and took pictures of Sona, who had a different magical girl outfit.
"Thank you! Thank you! Thank you! Thank you!" Serafall said. She hugged Issei. This was like a dream come true to her as Sona didn't like wearing a magical girl outfit. "Heh-he! Now I have hundreds of photos with Sona in a cute, sexy, alluring magical girl outfit!".
"You're welcome," Issei said. He felt that Serafall was around earlier, but he also realised that she was hiding from Sona. "Well, I did tell you before that if I had the chance, I would let you see your sister in a magical girl outfit".
"And you did as you promised," Serafall said. She then kissed him on the lips. This shocked Issei. "That's just a little reward".
"About that, Sera," Issei said. He didn't know how to tell her that he already had a girlfriend. But he thought it would be best to be straightforward. "I have to tell you; I already have a girlfriend".
"W-What?! W-When did this happen?!" Serafall asked. She hoped to someday invite Issei into her Peerage, but she found out just how strong he was, and she was incapable of turning him. So, she thought maybe she could be with him not as his master but as his girlfriend. But now, he had a girlfriend! Unacceptable! "W-Who is it?! I will not stand for this!".
"Sera, calm down," Issei said. The only to calm down an enraged Serafall was to hug her and make her forget what made her angry in the first place. Or have Sona act cute in a magical girl outfit. "Please calm down".
Serafall hated that Issei was capable of easily calming her down. She hugged him back, and she started sniffing him. This was something she does occasionally when she's around Issei. How Issei didn't know she was being affectionate is a mystery.
"Okay… I'm calm. I won't kill her," Serafall said as she gritted her teeth. She then took a deep breath to remain calm. "Now, can you tell me who this hussy is?".
"I don't know if I should," Issei said. She was only teasing Serafall. "You seem to still be out for blood".
"Wha! I am not!" Serafall said. She turned around, crossed her arms on her chest and pouted. "I just want to talk to this person to ensure that she's not taking advantage of you".
"If you want to meet her, she lives at my house," Issei said. Serafall looked envious. She wanted to live with Issei before, but she couldn't since she was a Satan. Serafall had responsibilities. "But you have to promise me that you won't attack her".
"I won't. I know that if I did, you'd hate me. I don't want that," Serafall said. She wasn't going to do anything that would make Issei hate her. She had already lost him as a potential boyfriend. She wasn't going to lose him as a friend. Although, it's not uncommon for strong people to have multiple spouses. "I promise I'll just speak with her. I just want to ask a few questions".
Issei smiled at her, and he brought her home. This wasn't the first time Issei had brought Serafall to his house. Miki and Gorou know about her being a Devil. Though Serafall was Serafall, Issei's parents couldn't see her as a Devil. Serafall was so cute and playful to be a Devil, but they knew Issei wouldn't lie about it.
