Not my anime! New story! ^-^ The devil is a part timer is such a great anime! I finished the last few episodes today and then this idea hit me. As far as I know there isn't a single de-aging fic in this fandom, small as it it, so here you go! My gift to you! Enjoy. Oh and there is more to the bottle than just de-aginf. There's a purpose behind it. Anybody who guesses get's a free fanfic written for them!

Maou stared at the bottle on the table. It looked like a water bottle but inside was a strange, purple liquid.

Ashiya's eyebrow twitched a little "Maou-sama... What is that bottle?"

Maou sighed "I don't know. Some old woman gave it to me."

Ashiya's brow furrowed "Please explain."

~~Flashback~~

Maou was on his way home from work. He'd gotten a pay raise and couldn't wait to tell Ashiya.

Suddenly a person stepped out into the road and Maou stopped.

The person stared straight at him before smiling. "Hello."

Maou smiled back uncertainly "Uhh.. Hi."

The person came closer and Maou saw it was an old woman.

She reached into her pocket "Please take this." and held out the bottle.

Maou reached out and took it, more to be polite than any want for it.

The woman beamed "Good luck to you." then she bowed and left.

Maou stared after her for a minute, wondering why everything strange happened to him, before looking down at the bottle with a sigh. He resigned to deal with it when he got home and put the bottle into the bike basket before heading, once more, for home.

~~End Flashback~~

Ashiya nodded thoughtfully "This seems... dangerous."

Lucifer snorted in the background "It was just a little old lady. I bet it's grape juice or something."

Ashiya turned around with a glare "It doesn't matter the age or gender wicked people will always exist and you should always be cautious!"

Lucifer rolled his eyes "Yeah but it seems to random to be dangerous. It was probably just an eccentric old woman who was taking a walk. Maybe Maou reminded her of somebody." He turned to Maou "Are you going to drink it?"

Maou sighed "I don't know. Ashiya has a point. Wicked people come from everywhere."

Lucifer laughed "You're the devil and you're afraid of a drink from an old lady? That's rich."

Maou glared at him "Remember your place Urushihara!" before he turned to the bottle again "Fine. I'll drink it." He picked up the bottle and took off the lid.

Ashiya gasped "Are you sure my lord? We can't afford for you to get sick."

Maou nodded "I'll be fine." He looked down at the bottle, less confident all of a sudden.

He sniffed the opening, it didn't smell bad. However it also didn't smell like grape juice. Maou sighed then knocked to bottle back and chugged it. It was gone with in the minute. He sat the empty bottle back on the table and wiped his mouth.

The drink hadn't tasted back. It had tasted quite good actually. Ashiya and Lucifer were looking at him expectantly he smiled "Nothing to worry about! It seems harmless."

Ashiya sighed in relief and Lucifer smirked slightly "I told you."

Then Maou remembered "Ah! Ashiya. I got a pay raise today!"

Ashiya beamed "That's great news my lord!"

Lucifer perked up "Ah then I guess now would be the best time to tell you I bought a new playstation."

Ashiya fell to his knees before yelling "Why would you do that! we can't afford that!"

Lucifer shrugged "We can afford it more now then when I bought it."

Maou sighed "What a pain." a sudden wave a tiredness came over him and he yawned.

The bickering stopped "Are you tired Maou-sama?" Ashiya asked.

Maou nodded "Hai... I think I'll turn in for the night."

Ashiya nodded "I will make sure nothing disturbs your slumber Maou-sama."

Maou rolled his eyes "Yeah yeah." he was to used to Ashiya's formal attitude to let it bother him anymore. He got a blanket and pillow and fell asleep almost instantly.

Hours later something strange happened. The room was dark and quite, everybody had fallen asleep. As soon as the clock hit 3:00 a purple light appeared. It bounced around the room for a minute before floating over to Maou. It hovered for a second before disappearing into his forehead.

Maou's brow furrowed and he rolled over a small sigh falling from his lips before he calmed again. Everything was about to change.
