You were in the midst of helping Issei and the others clean up the pool.

"Ugh, I haven't seen water this filthy since the filtration plant in MegaDistrict 8 blew up and caused the pollution to seep into the water supply."

Issei: "I saw the camera logs in that vehicle. I thought something was going to jump out for a second."

Kiba: "Just keep cleaning. We're almost done."

The three of you finished cleaning the pool and climbed out.

Akeno: "Y/N, go shower before you put on your swimwear."

You did so, washing any filth off yourself before putting on your swim trunks.

"Still not used to this kind of fashion, but then again, I'm not into public nudity."

After you were finished putting your swimwear on, you went back outside and saw Akeno using her magic to fill the pool with water.

"What's with the fancy circles when using magic?"

Issei: "I don't know, it's just something we know is part of when it's being used."

Rias called Issei over to her and Akeno walked up to you in her swimsuit.

Akeno: "First time at the pool?"

"Y-yeah," you said, blushing a little.

Akeno: "How do you like my swimsuit?"

"You look very beautiful in it."

Akeno: "Thank you. Let's go swimming."

You and Akeno got in the pool and went swimming together.

Akeno: "Have you done this before?"

"An ally of mine taught me a little. Thought it'd be better than knowing nothing and drowning."

Akeno: "You're right about that. Are you planning on going back there?"

"When summer comes. I have to stop Infinite. And I had a vision of a giant tree."

Akeno: "A tree?"

"Yeah. It had apples and I felt it calling for me."

Akeno: "Well, It's not like I can stop you, but I'm going to let you go alone."

"I don't want you to get hurt because of me, again."

Akeno: "And I don't want you to die again. Whatever happens, we do it together. That's what we promised to each other when we were kids."

"When you were a kid. I'm still a kid, but in a teenager's body."

Akeno: "Still, don't do things by yourself. Besides, I want to get even with that bastard too."

"Alright," you said, "but can we keep this between us for a bit?"

Akeno: "Sure."

Akeno kissed you on the cheek and hugged you.
