In which Tet and boredom do not mix well, and a bet is placed between him and the siblings. Would be willing to open this one up for adoption as I would like to see this one expand past the first chapter!

If there was one downside to being the one of the three True Gods as they were now known, it was that immortality could be downright boring no matter how many games you played. It didn't matter if the rules varied or special restrictions were added...eventually things got to be more of the same with the only real deviation being who would win and how.

As such, it was Sora who came up with an idea that would have some rather interesting consequences and would end up spicing things up enough that they were no longer quite as bored.

"Hey Tet...how about a long-term bet?"

Tet looked at Sora, the older half of "Blank".

"What sort of bet?"

Sora smirked...it was a sign that he had come up with something good, which made Tet perk up.

The game, as it turned out, was rather brilliant in it's simplicity.

All Tet had to do was live through one lifetime as a "human" or it's equivalent in a world that was similar to the one Shiro and Sora had been born into. How he lived was up to him, but he wasn't allowed to violate the ten pledges that made up the core of Disboard.

Considering the world Sora picked, having stumbled across it quite by accident while "channel flipping" as he called it, Tet had a few conditions of his own. He was already intrigued by the idea since it meant doing something completely outside his own experience.

Specifically that in the event he was in a situation where he might accidentally violate the ten pledges (or more specifically the first one) then his powers as God could be invoked and he could temporarily draw himself and whatever threat was against his life into a pseudo copy of Disboard, thus unlocking his full power as a True God and giving him unlimited access to his abilities until the threat was dealt with in accordance to the pledges. The laws of upholding bets would remain in effect even when he returned to being human.

In other words, he could rewrite reality so long as it fell within the power of the Ten Pledges and there was nothing the local inhabitants could do about it.

Needless to say Tet was more than happy to agree to the idea, if only to kill his boredom for a while. Being human...or as much as a god could get...sounded interesting.

It didn't take much for them to set things up...after all, anything that would require Tet's presence could easily be covered by the siblings.

Nine months later...barely a blink of an eye for a god... a child was born in another world with the soul of a god.

His name...was Midoriya Izuku.

Time for the long game to begin.

Some time later...

Izuku wasn't discouraged by the fact he was born without a quirk. He had arranged things that way after all.

In a world full of strange and wonderful abilities, being born without made you an anomaly.

Honestly though, Tet felt he was already overpowered when the conditions were met as it was. If he had a quirk, there was a chance his power could slip and he could potentially violate the Ten Pledges by accident. And that was something he wanted to avoid at all costs.

Besides, games were more fun with a handicap. It gave them an extra level of challenge in order to win.

He was still somewhat baffled as to how he ended up friends with a literal explosive hothead like Bakugo though. Even if Bakugo didn't believe him for an instant when he claimed to be a god.

However Izuku hadn't taken into account how downright boring this game was going to be at first. It seemed like the only interesting job in this world was being a Pro Hero.

That being said he wasn't too enthusiastic about fighting villains. He had the sneaking suspicion that if he did become a hero, then he would be invoking his powers as Tet a little too often and might accidentally void the bet that started this game.

After all, you needed a decent quirk to be a hero from what he saw of the laws. Putting himself into life and death situations that would fit the requirements sounded like a really stupid idea.

So he waited, watched and learned as much as he could. As Sora and Shiro had demonstrated...repeatedly...knowledge was a power all it's own and could make or break your ability to win the game.

Since the society he lived in idolized All Might, he learned everything he could about the man and many other heroes and would seek out villain attacks for more information.

It would be this habit that would lead him into a far less boring life.

Even if certain heroes (namely a sleep-deprived cat-loving hero) would wish it otherwise.

Izuku was rather bored. Sure, becoming Toshinori's chosen successor had spiced things up by allowing him to join UA properly, but that had been the extent of any "events" to happen so far.

It was no wonder Sora and Shiro had been so bored living in this sort of world. The number of events in real life were so low that there was nothing to really look forward to!

Almost in answer to his boredom, the world answered with the beginning of a long-term event that was sure to spice things up.

And it started with the invasion of the USJ.

Izuku took one look at the outpouring of villains, and then the expressions of the teachers.

The second the lead villain...who has a severed hand on his face for whatever reason...says something about using them as bait for All Might, Izuku has to fight to keep the smile off his face.

Finally! He could get a break from this human shell for a bit and let loose!

He could feel the Suniaster react as the the requirements to unlock his full power were met. If he didn't act fast, there was a high chance he could violate the Ten Pledges he had set forth that were the core of his status as one of the Three True Gods.

Izuku...no, this was Tet now...holds the Suniaster up in his hands as he calls out the invoking prayer of the Ten Pledges.

"Aschente!"

Before anyone can understand what's going on, the world around them shifts in a way that makes it clear that something more abnormal than villains storming the simulation joint was happening.

"What the hell is this? Who's using a cheat code?!" demanded Shiguraki.

"Now I take offense to that. I think this qualifies more as 'evening the odds'," said Tet rather cheerfully.

Everyone looked up at the teen in midair, sitting on what could only be described as a throne with a strange jewel in his right hand. He had mismatched eyes and there was a sense of childish nature in his demeanor. He had a heart shaped birth mark under his right eye.

"Who are you?" demanded Shiguraki.

"My name is Tet. You can call me God, considering I am one," he replied calmly.

"I've never heard of a god named Tet," said Eraserhead.

Tet shrugged at that.

"Most of the people in this world worship heroes. I'm the God of Games," he replied.

"What do you want?" asked Eraserhead. Because he couldn't see any possible reason why the self-proclaimed God of Games would be here now of all times.

It would only be later he realized that Izuku was missing during the entire thing, ever since "Tet" appeared.

Tet smirked.

"Why isn't it obvious? I intend to play a game of course!"

Eraserhead had a bad feeling.

"Pass. I don't play games with my student's lives," he said immediately.

Tet didn't stop smiling, though there was definitely a sense of seriousness in his aura.

"You don't get a choice. Either both sides play or no one leaves," Tet said flatly.

Considering they were dealing with an entity of unknown power and ability, they didn't have much choice.

"What are the rules?" asked Eraserhead. The villains were mostly letting the heroes talk, since even they could sense they were outclassed by an apparent 'child'.

Tet beamed at him.

"Why it's quite simple really!" said Tet rather cheerfully, as he outlined the laws.

All murder, war, and robbery is forbidden in this world.

All conflict in this world will be resolved through games.

In games, each player will bet something that they agree is of equal value.

As long as it doesn't violate pledge three, anything may be bet, and any game may be played.

The challenged party has the right to decide the rules of the game.

Any bets made in accordance with the pledges must be upheld.

Conflicts between groups will be conducted by designated representatives with absolute authority.

Being caught cheating during a game is grounds for an instant loss.

In the name of god, the previous rules may never be changed.

Let's all have fun and play together!

Eraserhead relaxed a bit. Clearly this god had no intention of playing any deadly games if the first rule he set down was no murder or war.

It was one of his students that noticed one thing no one else had picked up on yet, focusing more on the fact that they weren't at risk of drying automatically.

"Wait...does this mean we can bet our quirks and actually lose them permanently?!" said Yaoyorozu.

Tet smiled at her for catching on to that so fast.

"I did say anything can be bet, so long as both parties agree the wager is acceptable."

Now thoroughly alarmed, both sides were rather terrified of what sort of games this strange god would concoct.

"Now...shall we begin?" said Tet with far too much cheer.

Outside the USJ...

All Might had rushed to the training facility after young Tenya managed to escape long enough to reach UA to warn them of the attack.

What he expected and what he found were completely different. The second he entered the USJ, it was like he was teleported to an entirely different world where the rules he was so familiar with were thrown out the window and he was at the whim of a fickle god.

"What do we have here? Someone else wishes to join the game?" said the floating figure, looking thoroughly entertained by the entire spectacle.

"Game?" repeated All Might.

Eraserhead looked torn between relief...at the appearance of All Might, and worried for reasons the other hero couldn't readily explain.

The black-haired underground hero looked at the floating figure with some concern.

"What would it take for All Might to join the hero's side of the game?"

The figure seemed to look speculative.

"Both sides must agree it's acceptable for him to be part of the games, and a toll must be paid since he's basically crashing mid-way through the contest," said the figure. "Otherwise I'm throwing him outside the area and blocking his ability to come back in."

The villain looked entirely too gleeful at the idea of bringing All Might into the 'game'.

"We agree!"

"We agree as well," said Eraserhead quickly, before the villain changed his mind.

All Might was very confused at this point, but decided to play along.

"Very well, what toll am I supposed to pay?" he asked.

The figure looked contemplative.

"Hmm... How about...ten years."

"Ten years?" said All Might. He didn't think he had ten years left.

"That's the price to enter, since you're entering so late. Either take it or leave it," said the figure.

"Very well," said All Might.

The figure snapped it's fingers, and he felt something shift in his body. He couldn't tell what was going on exactly, but he knew something big had occurred.

He hurried to Eraserhead to get an explanation.

"What exactly is going on?"

"The figure up there is called Tet. He calls himself the God of Games...though I'm inclined to believe him since my quirk hasn't worked on him at all. So far he's had us play rather childish games scaled up to hero level difficulty with our quirks being the agreed upon wager. Outside of screwing with us and occasionally busting the villains for being caught attempting to cheat, he hasn't caused any real problems. If anything he's kept the students safe from the worst of the damage that could have been done to them from the villains showing up like this," said Eraserhead grudgingly.

Considering that if the 'god' hadn't shown up there was a very real chance his students could have been killed, he was reluctantly grateful for his interference.

Did not mean his headache was any less trying to figure out the boy's angle.

All Might's appearance lead to the 'final' game. The Noumu was already out due to Shirugaki's first attempt to cheat by adding him to a game he was about to lose...the loss of whatever quirk it had caused the thing to self-destruct as the thing was little more than a vegetable.

The villain had thrown a massive tantrum over that, and had been rather pissed when Tet cheerfully pointed out that obvious cheating was against the rules and that he had been warned.

In the end the heroes won as the villains, baring two or three like Shirugaki and his shadowy companion, lost their quirks.

Tet disappeared as mysteriously as he had appeared, and it would take some time before anyone realized Izuku had been 'missing' the entire time the god was present.

It wouldn't be until All Might reverted to Toshinori that he got the shock of his life.

The wound that had forced him to retire and look for a successor was gone and he had lost years off his current age. He felt like a new man and wondered why the strange god had given him a new lease on life.
