Whatever it takes, just for a rematch.

The supreme god Tet was bored.

It was already more than 6000 years since he became the One True God of this world. He had set up the rules of the world and waited for the one who could challenge him. So far, no one had realized his intention. This world was still the same. Nobody had the aspiration to challenge him, they only concerned themselves with their petty squabbles.

At this point he tried to travel to another world to see if anyone could be brought in to his world to spice things up. With the condition of Imanity Race, they would need a savior. That would be the excuse. With that thought, he journeyed across dimension.

After some searching, he discovered "Kuuhaku/ Blank" [ ]. The gamer sibling who reign in all of the online game in a certain world. But before he could investigate further, he got distracted by another thing.

It was a pocket dimension in a small city named Fuyuki. It was a world where nothing happened but everything inside was happening. It was an unreal world where things were real. It was a four days timeloop in infinite iteration.

Tet entered inside it and found that the world was essentially a game. More precisely, Eroge. With a dense harem protagonist who ran around searching for clues.

However there was something else that took Tet's attention. There was a minigame inside. Curiosity won and he entered it.

ILLYA CASTLE: EINZBERN ASSAULT.

NEW GAME -)

Tet found himself inside a building. The floor was created from wood. There's a writing in local language that say: "Tiger Dojo"

There were people waiting. A guy in blue suit greeted him. "Hey, I haven't see you before. You're a Servant?"

It seemed that it was a competition in which Master and Servant took part. The guy who called himself Lancer didn't bring his Master. Just like a woman dressed in robe and cowl. The others were Master and Servant pair.

"Don't worry!" Lancer said to Tet. "Having a Master was not guarantee that you will win. Be confident!"

Tet thanked the nice guy. He mingled around and got to know the people. There were Saber with her Master Shirou, Archer and Rin, Rider and Sakura, and Caster who came alone.

A woman named Taiga came and gave a speech."Welcome chosen ones!"

It was basically saying that her apprentice rebelled and challenged her. So, the teams gathered here would storm the castle and bring her down.

"Your target is Tempest: Illya's Castle!" Taiga ended her speech.

Tet inspected himself. His power had been reduced, possibly to be on par with the 'Servants'. He had to play by the rules of this game. There was HP. There was MP. And there was Noble Phantasm.

What was Noble Phantasm?

Tet didn't know. And that's why he lost in the first round.

They just had to jump across the lake on the floating stones. He got the last place.

It couldn't be helped! All of the other players were cheating! Archer called upon hail of swords upon him! Another, Saber, shot a blast of light energy from her sword! He had no chance!

And who put food on the floating stones? That was more of impediment. Eh? Why were the others eating them?

And this is a fighting game? Nobody said that! When two participants got close with each other, they fought it out.

"Lancer died!" "Idiot!" "Stupid!" So cruel!

Whoa! What is that black thing with tentacle which rose from the water?

"What? You think Holy Grail War is some kind of game?" Saber said. I don't get what she meant at all!

And the Masters didn't really help, only cheering and gave useless order from afar.

Tet had went quite far when Caster used Noble Phantasm. Suddenly a samurai came out of nowhere and slash him! He automatically went back a few steps. Tet now knew that Noble Phantasm mean that kind of things. It made no difference though. Tet didn't have any! It's unfair!

As mentioned before, Tet got last place.

Second woman, Taiga is back. "Welcome my surviving elites! The trials continue! Okay off you go! Use your strength to cook them to perfection! Mushroom Trip!"

Tet didn't understand a single thing from her instruction. He observed the other participants to know what he should do.

They had to jump to a huge poisonous mushroom. It is floating in the air and spinning, and they should grab it and got across. Why? Who the heck designed this game?

"You're in the way! Fall off!" Lancer said.

"Shut up Lancer." Archer said and hopped to a wooden plafform.

"I win!" Lancer said, but he misjudged the timing and fell to the chasm below.

"Lancer died!" someone said. "You're not human!" Another commented.

Tet somehow managed to get across. But it's bad, his HP had turned red.

To refill his HP, Tet must eat food. In light speed.

Impossible.

The blonde petite lady, Saber, ate so fast it was unbelievable. The other Servants also ate very quickly, leaving Tet in the dust. What kind of people were these Servants?

Eh, another mushroom? Whoa, he almost got hit by missile. He wanted to complain to the game designer.

"This mushroom has a springy texture." Archer said. What, you have time comment on that? You are so relaxed that you could afford to feel it?

"Yes, it is." Saber said. "Yeah, I know." Rider also commented. What's wrong with these people!

The last part was a cliff. They had to climb it without rope. And it was very smooth, without any place to grab. And the Servants could climb it! Each step consumed HP and Tet had to rest frequently to recharge. He fell down repeatedly until he finally managed to reach the goal.

No need to say, Tet got last place.

Third round. They had to cross the bridge while being harassed by cannon and flying maids. Tet suffered again from the lack of Noble Phantasm. And in the end of the bridge, a golden armored man was raining weapons. Tet couldn't get through.

When he was off guard, Saber knocked Tet out and used him as a shield. She managed to reach the goal and left Tet dying by the roadside. Evil.

When Tet got up, Caster did the same thing again to him and reached the goal.

When he finally reached the goal, he had wasted too much time and got last place. Again.

The woman, Taiga, appeared again. Now she gave a mission briefing.

This time, he also found out the name of the last boss.

"The detested castle is right before you! Throw down the challenge to the silver-haired mistress, but be careful!"

Taiga proceed by speaking about blood and tears and getting along. And mushrooms. Or something about cooperation...

"Now, proceed fearlessly my elites! Go and become the light!" Taiga said something incomprehensible.

Finally, at the last round, all the Servants teamed up together to bring down Illya and Bersercar.

"I am not an Einzbern doll. I hate adults! I hate society!" Illya said. Tet felt that there must be a backstory, if not, she was just a rebellious kid. "All of you... All of you should just die!" Okay, she was a psycho who need to visit a psychologist.

Tet was not contributing to the battle at all. He couldn't approach Illya or deal notable damage. All the other Servants had some fighting skill, but Tet didn't have that.

And what was this thing of having to eat in the middle of battle to restore HP? Yes it was standard in games, but to do it in real life? Crazy!

Finally, Illya and Bersercar was defeated. Tet didn't know how he managed to stay alive. Everyone else was also alive... no. Lancer had died.

The credit began to roll... and then an alarm siren went off. Illya weakly raised her head and spoke. "It's the end. In that case..." A button came out from the floor. "... you can all die with me!" She pressed it.

The castle shook. Illya pushed a button with her last power that would make the castle self-destruct!

"This is bad!" "Let's get out of here!" All the Servants were running left Illya who cackled madly amidst falling stones.

The Masters were riding a car from somewhere, so unfair!

The Servants were running while being chased by destruction. The one with slow movement would be left behind. Nobody would help you.

Who was the slowest of them all? Yep. Tet.

He fell down to the chasm along with Illya and Bersercar.

"The newbie fell down." "He was not fated to survive." "How sad."

Tet got transferred to a place together with Illya and her maids. Somehow, he knew that this was the place where the fallen one wait. There was a hole where he could see the outside of the castle.

There, some distance outside, he could see Taiga giving debriefing. The Masters and Servants were watching the castle collapsing. And then a man's voice gave the epilogue.

And then he saw the ending credit. And the score list.

Tet was 6th. The dead last.

Tet, the god of game, the unbeatable gamer, was dead last. The loser.

Unacceptable!

"This is not the end!" Tet said even when the writing "The End" flashed across the sky. "I will bring you all to my world and we will play at MY TERMS!"

Having decided that, Tet used his power and opened a dimensional portal to his homeworld. He sucked everyone and everything.

'Huh?' It was strange. The Masters were not pulled. The Servants were sucked in by the portal, but the human Masters didn't even budge. Except Illyasviel, because the portal was opened right beside her. Well, she was standing right beside Tet, having fall together with the child god. And also the two maids, they were also sucked inside the portal.

Tet considered pulling the three human Masters with his power, but before he could do it, the miniature world collapsed. It couldn't maintain itself with the strain of open dimensional portal. And maybe because Illya's existence was important to maintain this world.

'Hmm. Yeah, I guess it's okay. The Masters didn't really do anything. What I need is only the Servants for the rematch.'

With that thought, Tet entered the portal and closed it.

=====000======

I just got a flash of inspiration and had to write it.
