"YES, SIR WE DO!" The two Saiyans screamed.

Korin smirks. It has been a while since he trained someone. And he likes the look in their eyes, full of excitement and determination.

'Very well,' he said while pointing at this weird bottle at the centre of the platform.

"If you want to get stronger, then all you have to do is to drink this," he explained.

"Is it some magic liquid that increases your strength?" Izuku asked curiously.

"Correct! This flask contains a special liquid that increases your strength many folds. However, before you can drink it, you have to grab it from me! There is two of you, so in terms of numbers you guys have the advantage!"

"Grab a flask from you? Okay, I can do that!" Ochako said excitedly, going into a stance.

Izuku did the same, already coming up with strategies.

"3...2...1..."

.

.

.

"GO!"

And so the two dashed in front of the cat, desperately trying to grab the flask. While Ochako seemed to be fast but lacked a strategy. Izuku, on the other hand, seemed almost hesitant but had some tactics.

Both however did not see Korin take the Nyoi-bo and the Senzu. It was only after korin threw them off the tower.

"HEY, ALL MIGHT GAVE ME THAT!" Izuku yelled, launching himself off the tower trying to retrieve his belongings. Ochako quickly followed behind.

"Did he just say All Might? Well that explains it!" Korin muttered as his mind went back to the time when he trained the symbol of peace.

——————

3 days later

"Oh, you two are back! And in only three days! Astonishing!" Korin said while Izuku and Ochako look like they were about to collapse.

Ochako took out two Senzu beans, giving one to Izuku and eating the other. Korin sensed their ki spike up, surprised at their new level.

"My, my, both of your ki has increased by a big amount!"

"Whats ki?" the two Saiyans asked.

"You don't know what it is yet? Well then, allow me to explain. Ki is the energy inside every living being that can be drawn out with enough focus. The ki can be then be manipulated and used. It also takes a long time to concentrate. Also, because there are physical limits to the strength of the body itself, it is necessary to increase one's ki to overcome this barrier and become stronger. Fighters can also use ki to power up.

There are three types of ki: Regular or good ki, evil ki and godly ki. Regular ki is the most common ki, with users being able to access special attacks. Regular ki users are usually good. Evil ki is like it looks, belonging to well, evil people. Last but not least, Godly ki, which is used by Gods."

Izuku nodded, while Ochako asked, "Aside from attacks and powering up, what else can you use it for?"

Korin answered, "You can also use ki to fly and sense other ki."

Ochako smiled at that statement. Those were sure useful skills for a hero!

Izuku asked, "Do quirks affect ki? Like quirks that increase physical attributes?"

"It depends on the quirk itself," Koirn responded. "As you said, quirks that enhance physical attributes increase ki as well."

"Anyways," Korin continued, "Since it's sunset now, I decide to call it a day. I will teach you ki tomorrow along with what's going to be your daily routine for now. Good night." He said as he sat down and fell asleep.

"Well then, good night Midoriya," Ochako said as she slowly lied down.

"Goodnight Uraraka." He replied.

--

Izuku couldn't sleep.

The reason? He has to sleep on a stone floor.

"Can't sleep huh?" He heard, realising that it was Ochako.

"Me too," she added, as she looked up to the night sky, where a crescent moon was displayed.

"Hey Uraraka, have you seen a full moon before?" Izuku asked.

"Nope. Come to think of it, my parents were on high alert whenever there was a full moon for some reason. Like, they would always make me go to sleep extra early." She replied.

"Me too! My mom was constantly worried whenever there is a full moon. She never told me why though. Whenever I asked, she would respond with, 'When you are older and ready, I will tell you.' I looked in my record at the quirk registry, but it just states that I have a tail. Nothing about the moon."

.

.

"Hold on a second, this might sound rude but, Uraraka, how would you describe your appetite?" Izuku asked, looking as if he had some suspicions.

Ochako froze.

Out of all the questions he can ask, why that one?

"I would...say that I...have a pretty large appetite," she answered.

Izuku nodded, then asked, "Did you check your Quirk registry record? If yes, then what did it say?"

"It just said I had a tail. Why do you ask?" Ochako replied.

"It's weird," the green-haired Saiyan questioned, " If something happened on the full moon, wouldn't it be recorded at the quirk registry? We both have pretty large appetites too, so wouldn't that be recorded too? Did our parents not put that information for a reason? If it was for a reason, then was it? Are our quirks special or something?"

.

"Or is it something more?"

——————————

The next day

"My, my, All Might sure picked up some prodigies!" Korin thought as he watched his two students charge ki in their hands.

"At this rate, they will have mastered the fundamentals by tomorrow!"

"Alright, alright, let's carry on tomorrow! Now then, shall we continue!" he signalled to Ochako and Izuku, who extinguished the ki in their hands, got into a fighting pose and began to attack.

————————

They got it!

Finally, after 1 week, they got the flask!

Izuku and ochako became proud of them selves, smiling as if they won a competition.

ann

"Well then, go ahead!" Master Korin said, allowing them to drink.

And so, Izuku, who was holding the flask, opened it and drank...

Water?

Just pure, ordinary water?

"Hold up!" Ochako yelled, " I don't sense any change in Midoriyas ki! Did you lie to us!"

The master only giggled, amused by the fact that he had been accused of lying.

"This is just, water." Izuku said.

"Of course it is! This is just rainwater!"

.

.

"WHAAAAAAATTTTTTTT" Izuku and ochako yelled, clearly shocked.

"So you lied to us!" Izuku screamed.

"Meowhaha! I didn't lie! Your strength has already grown many-fold! Think of all the times you tried to take the flask and climbed the tower!"

It finally clicked in their heads.

God they were idiots.

"Now then," Korin continued, go back and test the fruits of your training!"

"Yes sir! Bye!" Izuku and Ochako yelled as they waved goodbye to Korin and flew back to their own homes.
