Harem Hero

Aftermath

Unfortunately, there was an imminent threat that Issei's girlfriend was going to castrate him if he left her sight for any longer than thirty minutes, so under recommendation from Rias you decided to send him back to their world before that could happen. Before you left the scene, you spotted a red scale resting inside one of the craters. It must have been knocked off of Issei's armour during the battle. Not wanting the enemy to take anything away from the fight, you retrieved it and put it into your pocket.

With your first date with Asia wrapped up and the invaders repulsed once more, you decide to retire to the garage and see if Mitsuru had made any progress on her form change device. You can hear the whirring of her machinery as you approach the front door. She's hunched over a bench with plastic goggles wrapped firmly around her head. Sparks fly from beneath her.

"It appears that Mitsuru-san is busy..." Asia whispers.

The whirring stops, and Mitsuru places a small tool onto the bench beside her; "Actually. I just finished. Thanks to my own intervention completing the advanced translocator was easy enough that even a dullard could have done it. Though there is still one missing component."

You chuckle, "What? He didn't even tell you how to complete it?"

Mitsuru opened the top of the device and showed the internals to you. A large space had been left behind. It was entirely intentional. The arrangement of the parts that had been hinted to in the paper had made that space on purpose, and several diodes pointed inwards to connect to whatever that missing piece is. As you start at the shape, an idea starts to form in your mind.

You reach into your pocket and place Issei's scale down onto the work desk. What a freakish coincidence. It was almost like your son from the future already knew that this was going to happen. Mitsuru reaches over and holds the scale over the slot, her brow furrowing in irritation.

"Typical. I was getting worked up over nothing." Mitsuru didn't hesitate, sliding the scale into place and pinching each side with a small conductive clip to connect it to the system. The mechanism whirs to life for the first time. Mitsuru does a small jig in celebration; "My future genius knows no bounds."

"Isn't this kinda' cheating?"

"I still discovered it in the end!" she snaps back. Though this time loop does beg the question of who discovered this thing originally. Since Mitsuru is informing herself about how it works, it technically means that nobody has ever come up with this without outside intervention. This is both extremely confusing and not worth the effort to think about – so you discard the problem and just roll with it.

Mitsuru returns to the computer and checks the readings, "That scale contains an incredible amount of power. This is what my future self must have intended."

"So does that mean I can do this form change thing now?"

Mitsuru waves her hand in the air, "Give me a few hours to figure this out. I should be able to use the data from the scale and your previous battle to make something special for you."

"As long as it means I can deal with Vali myself..."

Rias shrugs, "Issei will never object to knocking him down a few pegs."

"Sure. But at what cost?"

"She isn't going to castrate him that badly," Rias smiles.

"I'm sure she's really happy that her boyfriend is in a club filled with nothing but beautiful women."

Rias smirks, "And a beautiful boy."

"Sure. Kiba too."

"I've never been called beautiful before," Asia whispers. Given that she has the face of an angel and pretty blonde hair – you aren't really sure that's the case. Were all of the people at her church blind or what? And while you'll never reveal this out loud, you've seen more than enough of her body naked to know it's no slouch in the curves department; unless you're comparing her to Rias and Akeno. That's an unrealistic standard to attain for most. They both have bodies that a perverted twelve-year-old would scribble down onto a scrap piece of paper for fun.
