(I wanted to do this after I finished my pkmn mystery dungeon explorers of darkness, so here is a long awaited one-shot, pairing: male riolu x female pikachu. Oh yeah for those of you who are still playing the game, Spoiler alert)

Noel and Sierra have defeated Dialga and have placed each time gear in Temporal Tower and saved the planet from paralysis. On their way back to the rainbow stoneship Noel (riolu) noticed his body was getting stiff but Sierra (pikachu) didn't notice until Noel saw a light.

(I don't remember the words so I'll just try to remember and make a few up, actual moment in the game)

"Noel what's wrong, come on lets get back to Treasure Town" Sierra said.

"I'm sorry Sierra this is where we say goodbye" Noel said.

"Wha- why!?" Sierra asked in shock

"Because I'm a pokemon from the future and since we stopped my future from happening, I will cease to exist.

"Noel, please don't leave me, I wanted to join the guild but I was scared until you helped me become strong and brave" Sierra said in tears.

"No Sierra! You must become strong on your own, but even though I wouldn't exist, I'll always remember you Sierra" Noel said as the light was becoming stronger

"Whenever I'm scared or losing hope, I'll always remember you" Sierra said in tears and hugged Noel before he disappears.

"Sierra, just know I...love...you..." Noel said then disappeared.

"Noel...NOEL!" Sierra shouted out in sorrow as her partner and her best friend was gone forever.

Sierra then arrived back at Treasure Town and told everyone about what took place in Temporal Tower. And all went well for the town.

Noel's POV

It was dark,cold, and had absolutely nothing. I thought paradise would be better than this. In this dark place I remembered every moment I've had with Sierra. From joining the guild, defeating Groudon, breaking free from the clutches of Dusknoir, and the saddest of all, losing Sierra.

"I wish I could go back to Sierra" I said.

"Then your wish is granted" A voice said and when I turned around, I saw Dialga infront of me.

"I know how much you loved that pikachu Sierra, just as much as I loved the pokemon of space but parted ways due to the inebitable" Dialga said.

"So I can go back to see Sierra once more?" I asked

"Are you sure once is all you ask?" Dialga asked.

"No, I wished to stay with her for as long as I lived even though I'm considerably dead" I said.

"Then your wish is granted" Dialga said then light surrounded me once more and I appeared on the beach and at the exact same spot I've met Sierra for the first time.

I saw Sierra was crying, crying out my name while Bidoof was trying to confort her. She then saw me with teary eyes and she than ran and tackled me to the ground and tightly hugged me as her tears of sorrow were now tears of joy.

"Noel, I love you too" Sierra said and we both kissed and ended the kiss so Sierra could get me on my feet.

Months have past and we've both defeated the guild in terms of our graduation exam. We then lived in Sharpedo Bluff where our base of operations were at. We were once again Team Dawnshadow (wierd name, I know)

It has been a year and we were strolling be treasure town until we saw the area was filled with festival ornaments being hanged up on wires above us.

"Hey Corphish whats with all the decorations?" I asked.

"Its for the Treasure Town's cultural dance festival" Corphish said.

"The what?" Sierra asked.

"Its the town's festival for cultural dance and since you two are a couple now, you should join" Corphish said which made me and Sierra blush a bit.

"I'm going to ask Sunflora to it" Corphish said.

"Um, Corphich you know she's been asked by Bidoof already and has gladly accepted it.

"Awww" Corphish said in disappointment.

"We've got a lot of jobs to do today, so I don't think we'll make it" Sierra said.

"Oh well" Corphish said then left.

We then went off to do our jobs. And got back in the middle of the festival. Almost every pokemon in treasure town were there very few pokemon were still in their houses or shops. We just stayed by a nearby oran berry tree then we heard a panflute playing a song that couples were going to dance to.

(Background music: I don't want to say goodbye

Pkmn md explorers of darkness ending theme, thought it would be good for the moment)

I then stood up and offered my hand to Sierra.

"Do you wanna dance?" I asked.

"Yes" She answered and we did a slow dance together and did it perfectly (try to imagine how it would look like)

A few guild members saw us and smiled as our love for each other grew stronger and stronger and we were inseperable

for now and forever
