The next day after school, Rias Gremory and her servants formally faced the two exorcists. Rias and Akeno were sitting on the sofa while the rest stands at their backs. On the other side, Irina and Xenovia are also sitting on the sofa with only a center table separating them.

Rias and Akeno has contrasting expression. While Rias is wearing a serious expression, Akeno, on the other hand, wearing a smile that doesn't reach her eyes.

Due to some incident last night after the bath, they only looked Rias and ignored Akeno... or more like they didn't want to look at her due to how awkward it was last night.

Yesterday night, after their bath, they unpacked their luggage and went to the living room to wait for the food to be delivered. They want to be the ones who receive the food. And after a few minutes, the delivery guy arrives and they don't need to pay since Akeno already took care of it.

But just after they finished dinner with a satisfied expression, they heard a weird sound coming from upstairs. Curious to what it was, both of them looked at each other and decided to take a peek. They slowly and silently made their way towards the second floor.

It's coming from a certain room and as they approach that room, the sound became clearer for them. It's the sound of Akeno's voice... the sound of moans... of ecstasy. The two looked at each other again, confused with what's happening on the Devil maid and what she's doing right now. Nodding at each other, they proceeded and reached the door where the sound is coming from. Using their Holy Power, they used simple sound-insulating magic so that they could open the door without any noise, but to their surprise, their Holy Power dispersed when it hit the door, but there is a feedback that it was successfully cast.

They looked at each other again in confusion, not knowing what happened. Irina tried it again, but this time, only around them. A small transparent barrier covered them both before disappearing into thin air. This is the normal activation of sound-insulation magic. The barrier magic produces indeed disappears after it covered the target so that it wouldn't be too obvious for others to see. But they can at least tell that the barrier wasn't dispelled.

Irina then tried to expand its radius until it hits the door. But as they expected, it was dispelled. The strange thing is, they only confirmed it through vision and there's still feedback that the barrier is still expanding. In other words, something or someone is feeding false information about the state of their magic. If they didn't see it for themselves, they would have really thought that the magic is still in effect.

Irina and Xenovia shuddered at the thought that someone is controlling their magic senses and they didn't even realize it. If not for their instincts telling them that there are no danger or any malintent, they would have retreated instantly. But they became more curious as to how is this possible and thought that Akeno has something to do with this.

Signaling each other, Irina grabbed the doorknob and took great care not to make any noise opening the door and she was successful as they noticed that the moaning voice kept going and increasing in frequency. Xenovia prepared her sword just in case something happens.

From the gap of the door, they simultaneously took a peek and what they saw blew their minds... A maid is laying on the floor with a disheveled attire with her left hand holding a magazine while her right hand is rubbing her intimate part. A few seconds later, she increased the pace of her right hand as she arcs her body upwards accompanied by a silent scream. Moments later, she stopped and dropped back to the floor breathing heavily with a flushed and satisfied face.

Due to how shocking the scene was, Irina immediately closed the door but she forgot to be secretive about it and made a loud noise which instantly caught Akeno's attention, "Ah..."

"Who's there!?" Akeno hurriedly stood up and almost tumbled down in panic as she fixes her clothing while running towards the door. She opened it and saw the two exorcists having differing expressions. Xenovia is looking at her with a puzzled expression, while Irina has a flushed faced covering her mouth with her hands.

"Y-you saw...?" Akeno already got her answer from their expressions, but she asked regardless of hoping for a miracle.

"What were you doing?" Xenovia asked, trying to understand her actions earlier.

"Xenovia!?" Irina didn't know what do to do with this awkward situation. She just wished that she could escape and forget about all of this.

Instead of answering her, Akeno returned her question with another question, "What are you doing here?"

"Well... You're making a lot of noise and we had to check it." Xenovia answered honestly.

"Noise!? Impossible! I cast a sound-insulating barrier around the room! There shouldn't be any sound coming out of the room!"

"You don't believe me? Try doing it again, but this time, from the outside." Xenovia suggested.

"That's impo..." Akeno was about to refute her again, but she finally remembered where she is... She's currently in a 'Demon Lord's Dungeon'. Akeno stepped out of the room and with her shaking hands, she tried to cast a barrier around the room, but just like with Irina's barrier, it was dispelled with the feedback that the magic kept ongoing. Realizing this truth, Akeno dropped down to her knees and covered her face with both of her hands, "Wahhh!!!" She screamed in despair.

Using this chance, Irina dragged Xenovia with her to escape to their room. The wails of despair and hopelessness kept on ringing for a few more minutes, but it seemed that the Devil maid won't follow them as they suddenly felt her Demonic Power moving away and disappearing in the distance.

Irina sighed in relief, but she forgot another problem, "Irina... What is she doing earlier?" Xenovia asked her.

She then has to explain to her, reluctantly, what Akeno is doing. It took most of the night for her to introduce Xenovia in that sort of thing.

So when they met again in the clubroom, both of them are trying their best to ignore the threatening atmosphere coming from Akeno.

"Akeno? What's wrong?" Rias already knew how Yuuto would react and just like what she expected, she can hear Yuuto grinding his teeth while revealing a murderous aura. But she's baffled with Akeno's apparent hostility with them even after considering that they are from polar opposite factions, 'Did something happened yesterday? They did stay with Akeno last night, after all...'

"Ara~. It's nothing, Buchou. I just have a really strong urge to strangle a grinning man wearing a bucket hat with white and green stripes pattern~."

"T-that's awfully specific, but cease it... There is no one like that in here right now."

"That's too bad~."
