That day, Tendo Souji celebrated his fourteenth birthday.

However, his parents, who should have been congratulated the most, were no longer in this world.

It was the day that Tendo felt the loneliest day of the year.

Naturally, Tendo's feet were directed towards Shibuya.

But it seems that he has no business in Shibuya.

Tendo's parents used to work in Shibuya when they were alive. For that reason, Tendo has a habit of walking around Shibuya once a year on his birthday.

However, Tendo suddenly passes by those who murdered his parents.

Tendo found himself about to stop.

But the killers continued walking

without noticing Tendo.

Ironically, those killers have the exact

same face as Tendo's parents.

That's because they were

some mysterious lifeform that took on the form and face of his parents after killing him.

For Tendo, it was the nostalgic smiling faces of his parents he hadn't seen in eleven years.

But those were also the despicable faces of the murderers he swore to avenge.

Love and darkness swirled into his heart, making his blood boil.

That terrible event happened when Kusakabe Souji was three years old.

His parents were killed by two giant insect creatures right in front of his eyes.

Then two terrifying insect creatures transformed into human forms.

And it was Souji's parents.

At that time, Souji didn't understand what was going on.

It was such an absurd fact that even adults could hardly accept it.

But Souji's instincts told him to run.

And by some miracle, he survived.

He was adopted by his grandmother, taking the last name Tendo. He was no longer Kusakabe Souji, but Tendo Souji.

Tendo was unable to speak for a while due to the shock of his parents being killed right in front of his eyes, but as he grew older, he gradually understood exactly what happened on that fateful day three years ago.

"They're probably not humans... They're some kind of monster that humanity hasn't recognized yet... So even if I try to explain what I saw that day to the police and the adults. around, no one believes... But they're definitely real. And even now, they are still wandering around without being caught by the police, wearing the same face as their parents, and enjoying the happy family life they took from them..."

Tendo was only seven years old when he swore to avenge those monsters, he started training his body.

"I swear they will pay for what they did..."

That became Tendo's sole reason for living.

Revenge is everything to him.

There was another reason to support his determination to get revenge.

At that time, there was a baby in the womb of his murdered mother.

They knew it was going to be a girl.

His parents decided to name him "Hiyori".

Kusakabe Hiyori.

Every time the three-year-old Souji had a chance, he would call out to his sister who was still in the womb.

"Hiyori, you are my brother. Can you hear me? I really want to see you, Hiyori-san..."

And that only sister died while still in the cradle called the womb, never having a chance to see the world again.

"Hiyori died before she was born."

Whenever Tendo thought that, the fire of hatred burned within him.

He wanted revenge at all costs.

Vow to avenge not only her parents but also Hiyori.

He was walking through Shibuya with the curse of revenge.

Tendo carefully ensures that his appearance is secret when following them.

"I will kill them. Definitely, no problem."

By chanting those words in his heart, he wrung out every bit of courage he had.

After all, they were cold and violent monsters who murdered their parents like nothing happened.

Creatures that even an armed adult would struggle to defeat.

A fourteen-year-old like Tendo, who was still developing, would be inferior to them both physically and in strength.

Furthermore, they are not human.

"That's why I train my body. All I did was for today... I lived this long just for the sake of avenging my mother, father, and sister..."

Up to a point, Tendo had begun to keep his raw weapons with him at all times, ready to avenge himself if he came across an enemy.

It was just a cheap knife he bought online, but it had been sharpened to the point of being able to cut someone

It was just a cheap knife he bought online, but it had been sharpened to the point of being able to cut someone just by touching it. Moreover, the handle has been laminated, making it impossible for it to slip out of the hand even in the presence of blood.

Tendo shoved his hand into his pocket and grabbed the knife as he chased his enemies with fierce bloodlust.

Enemies descend heading for the Hachiko.

As he chased, Tendou thought to himself
