First, an encounter with a classmate, and a visitor!

Issei walked up to Asia, who was happily chatting with Aika Kiryuu, another student in their class, one of the few girls who didn't seem to mind Issei's perverted antics. "Hey Asia, you ready to go to club?" Issei asked her.

"Oh, that's your boyfriend, right?" Kiryuu remarked to Asia with amusement, and Asia, though blushing, nodded. "Gotta say, you're a lucky guy~!" she chirped at Issei. "Asia's been telling me all about you, and your other girlfriends!"

"Wait, what!?" Issei demanded, looking at Asia.

"Ah- n-none of the more private details!" Asia told Issei frantically. "Just let her know I'm in a polyamorous relationship!"

"Oh, private details?" Kiryuu grinned, adjusting her glasses with an impish grin. "You been trying out the things I suggested with Issei, Rias and Akeno? I could always lend you my stra-"

"And, we're done!" Asia yelped, grabbing Issei's hand, and moving with him out of the classroom, Kiryuu laughing after them.

"...yeesh, she's like a female version of me and those two idiots sometimes," Issei noted as he followed Asia. "So... She's been giving you advice?" he asked her.

"Nothing major," Asia blushed. "Just... a few ideas on how to initiate some of our... fun..."

Issei smiled a bit awkwardly, but he had to admit, that actually sounded kind of fun, if Asia ever decided to have the initiative to act on said advice. They reached the club room, and Issei entered, starting to say, "Sorry we're late-." He paused as he saw that there were two others in the club room. And one, he recognized. "St-student council president?" he asked in surprise.

Rias smiled and stood, gesturing towards the bespectacled woman, who also stood. "Allow me to formally introduce you both. This is Shittori Souna. As you both already know, she is the student council president."

"Nice to meet you both, Hyoudou-san, Asia-san," Souna nodded with a polite smile and tone.

Asia gave a respectful bow, and replied, "Same here, nice to meet you too!"

Issei nodded and added, "It's nice to meet you as well... but, um, why is she here?"

The guy who had been with Souna scoffed, and asked, "Serously? Did Rias-senpai not mention us to Hyoudou?"

Sona glanced back at the guy, and lectured, "It couldn't be helped, given we're not supposed to interfere in each other's Devil Affairs. Also, he hasn't been a Devil for long, so it's only natural he wouldn't know yet."

"...wait, what? You guys are Devils too?" Issei asked in shock.
