Tokyo, June 21, 2040.

A 12 years old boy with purple and spiky hair to his upper right and yellow eyes was sitting on the couch in the living room. He was playing on his newly purchased ZBox.

Defeat after defeat.

The game had superheroes as its theme. His dream was becoming a level 7 hero. His name was Ishikawa Yuto.

Defeat again.

— Oh man, I suck at this game. Being a real hero shouldn't be that difficult.

The door to the room opened and a woman with orange eyes and red hair that falls to the shoulders entered.

— Yuto, are you still obsessed with this game? I told you that being a hero is not that cool.

— Big sis! How was it today? How many bad guys did you defeat this time?

— Yuto, I don't defeat anyone at work. I just show up in places and the troublemakers flee in despair. For this and many other reasons you should stop idolizing heroes...

An awkward silence filled the room.

— Big sis, I've already made up my mind: I'm going to join the association. I will become a level 7 hero like you.

— What? But brother, didn't you hear what I just said? Being a hero is not cool-

— That's exactly why, Kanata. I want to protect you. We are brothers and must help each other. I know I'm just the younger one and you are the top 1 of the association, but I don't want you to feel alone.

— Yuto…

— And nothing you tell me will stop me from getting a power and becoming a hero.

Silence fills the room again, but for much longer.

— Are you sure? This could be the worst decision of your life, and I won't always be able to protect you. Furthermore, many people will go after you just for being my brother.

— Absolutely sure, sis. I will get stronger so you won't need to worry about me.

— Alright. I still completely disagree with this, but I can't deny my little brother's will.

— Really? Can I really be a hero? Can I finally be like you?

— Yes, but for the first few days, stay close to me, because I will kill- I mean, prevent any troublemaker from touching you.

— Got it, sister. I will not leave your side. Thank you very much.

An hour later, the two brothers were at the association's main building. It was basically made of giant black cubes. It had an imposing aura and was located in the center of the city. There was no other building as big as that one.

As Kanata walked towards the recruiting queue, everyone in the line turned away from her path and offered their places, with fear.

— Tch, what did I do to make y'all afraid of me? I'm not a tyrant, you know? I'll stay at the end of the line because I arrived last.

If you spot this tale on Amazon, know that it has been stolen. Report the violation.

Yuto stared at his sister in amazement. He was proud to have such a strong and honest sister. She was his guardian, so nothing could go wrong.

It was Yuto's turn. Not understanding what he had to do, he looked confusedly to the green-haired girl in front of him. She appeared to be 7 years old or younger. She placed her hand on Yuto's shoulder. The guard gestured for the next one in line.

Uncomprehending, Yuto looked at his sister, who made an approving gesture. They went to the nearest square, where there were fewer people.

— Yuto, that girl is the epicenter of almost all powers that exist. That's why Tokyo is the city with the highest number of powerful people.

— But she only touched me. How could that give me a power?

— The next time you sleep, your power will awaken in you. It will be a dream where you can use it at will.

— I don't think I understand very well, sis…

— When we get home, you'll understand.

It got dark. Yuto, in his bed, started to rave. He was in his room, but didn't know what was reality and what wasn't.

Instinctively, he extended his hand towards his cell phone, which was on a table next to the bed. The cell phone was too far away to be reached.

When he realized, it was already in his hand.

— What? My arm is not that long.

He got up to look for his sister, who wasn't home. A green-haired girl was sitting on the sofa, playing on his console.

— Who are you? And where is my sister?

— It seems your power has finally awakened, boy. You probably already used it without realizing it. It's as natural as breathing. Try again.

Yuto concentrated for a few seconds. All living room furniture started to float. Startled, he released them.

— It seems that your power is something related to gravity, young man. It is a power with destructive potential. If you don't wake up now, this world goes to chaos, because you still don't know how to control it.

The girl approached and touched Yuto's shoulder. Desperate, he wakes up and falls out of bed

— Ouch…

— Yuto, are you okay? Are you hurt?

— I'm fine, big sis. I just had a weird dream.

— You have just awakened your power. Do you already know what it is?

— It seems to be gravity, I made the furniture in the room float.

Kanata pulled away and leaned against the bedroom door, bringing her hands to her face.

— This family is cursed with destructive powers. If one of us get out of control, we're going to destroy this city before we know it.

— Calm down, sister. I will use my power for good, not to destroy.

— You may think that now, but in a while you will be causing chaos before you realize it. People fear and hate me because of it. Power goes to the head, and we do horrible things as if they were normal.

— Sis…

— Sorry, Yuto, I shouldn't have lost my composure. Well, tomorrow you get to work, but don't leave my side. You need to train first, so I'll do your first quests.

Before Yuto could say anything, Kanata leaves the room, with a clearly troubled expression.

The next day, Yuto accepted simple missions such as delivering milk cartons to children in need, but her sister did them. It was a strategy to gain reputation faster than doing it independently. Finished five basic quests, his #823,543 rank from level 1 rose to #798,355.

He began his training with his sister in a square close to his home.

— First, Yuto, try using your power to throw that stone.

Successfully, Yuto made it levitate and threw it 5 meters away. After a week, the distance increased to 40 meters. After a month, he could throw a stone his size 100 meters away.

— Yuto, your power is like mine. It evolves extremely fast, but at the cost of being dangerously destructive.

— I don't think that's a problem, sister. If the bad guys are afraid of me, they won't even cause trouble anymore.

Yuto quickly rose through the ranks, reaching level 7 in less than a year. Now 13 years old, Yuto was top #7 in the association. Many envied his position, achieved largely by talent, but that didn't bother him.

Most of the quests didn't cause him any problems, so it can be said it was an easy journey. Or would have been, if it wasn't just the start…
