Hero Association

Few days have past since that little accident happened, none know or remember what happened.

At that time, people who was afraid and running at first just saw that the monster they running from became a mush of flesh and blood, not remembering anything about a kid who just slaps the monster like it's nothing.

Making the Hero Association staff left with a mystery in their case.

Even using mind reading on those people, they can't seems to remember anything other than they just run away from the monster then it just died.

...

The Hero Association was founded by multi-millionaire Agoni, whose grandchild was saved from a mysterious being by a passerby.

After hearing about the incident, Agoni came up with the idea for the National Superhero Registry and founded the Hero Association using private funds of businesses and donations from the public.

When it was founded, the Hero Association was initially divided from C to A-Class, and a similar system was used for monsters. For example, the disaster level Demon was not called "Demon," but simply "Mysterious Being that could only be defeated by a group of A-Class heroes."

The creation of the S-Class only came about as the Hero Association staff recognized that certain heroes were able to consistently defeat monsters that other top-ranked heroes failed to defeat.

To prevent rare talents from being hidden, they formed a special class.

This new class specializes in combat ability and is treated on the same level as an emergency army division. This new class came to be known as the S-Class.

The Hero Association Staff are the people who send reports to the public, whether it's a monster, natural disaster, or any other crisis.

Disaster Levels

Wolf: Any potential threat that poses a danger to an unknown degree.

Tiger: Any threat to a large number of people.

Demon: Any threat to a city and its people.

Dragon: Any threat to multiple cities.

God: A threat endangering the survival of humanity in general.

The one Rinku just killed is Demon Level Disaster.

As for the heroes, they also have ranking level.

S-Class Hero

-The strongest and most prestigious class of the Hero Association. Every hero in the S-Class is equivalent to an emergency army division. This class was originally created to gather individuals who, despite their low ranking, were capable of defeating disaster level Demon Mysterious Beings on their own.

A-Class Hero

-The second strongest class of the four classes. When a hero reaches Rank 1 in B-Class, they can climb up to A-Class. Heroes in this class are capable of defeating disaster level Tiger Mysterious beings alone and are also considered very popular.

B-Class Hero

-The third strongest class out of the four classes. When a hero reaches Rank 1 in C-Class, they can climb up to B-Class. Heroes in this class do not have to perform weekly heroic acts to fulfill any quotas, and are also capable of defeating disaster level Wolf Mysterious beings by themselves.

C-Class Hero

-The lowest and least strong class out of the four classes. Although C-Class heroes are the weakest, their strength exceeds that of an average person. When a hero enters the association, they normally begin here. C-Class heroes must perform weekly heroic acts to fulfill their quotas, otherwise they are removed from the Hero Registry.

There's also those unregistered heroes, who regarded by Hero Association as "WEIRDOS" and do not get any credits or mentions in any media.

This is where Saitama is when he finished his "special training method" and starts to do doing hero work, at first but later he became a "Hero for fun" guy since no one seems to be powerful enough to fight him.

It will start two years later though. And Saitama is already doing his "special training" one year now and still in the middle of doing his "special training" everyday. Though in half a month his hair will be lost for ever...

...

Few days ago.

After teleporting at home, Rinku puts Konata at her room then teleported back to erased any evidence about what really happened, erasing the recorded footage and memory of the people who saw what happened.

After that, he goes back at being a loving big brother this following days.

...

One more year passed, Rinku is already six year old, and ready to go to school. He and Soma will both go to the same school too. Also Soma was also starts to learn how to cook.

...

Ending there first school year, Rinku asked his parents to go to a amusement park in his summer vacation.

Hearing what his big brother just said, Konata was even more happy to go too.

Seeing his little sister happy Rinku thought 'I knew that she will like it' Rinku smiles at that.

"Okay, okay, relax, where do you want to go then?" Sojiro, his father, asked.

"The Amagi Brilliant Park!" Rinku said.

...

In this world, the Amagi Brilliant Park isn't run down yet, that will happen 5-6 year later, at that time Rinku will be in his first year junior high school.

That will be the same time Isuzu Sento will look for the prophecy that is Seiya Kanie, for 2 years, to become the new manager of the Amagi Brilliant Park.

...

Deciding that they will go the next two days, Rinku then continues to train, his lost time training ever since his little sister was born makes his training and body stagnate.

So next two days he got is for training in the Time Chamber, since it's one year inside the Time Chamber he swiftly got used to it again.

Increasing his masteries in different skills and still training hard from his martial arts training but it was hell for him. The hardcore 1v1 with the puppet is still hard for him, even with the help of the unique skill [Super Growth].

Since martial arts comes from battle experience.

...

Two days have pass in the real world. The day of fun awaits.
