Haven't read the novel. Don't know the real story. But I use the names of the real charas... Hibiya and Hiyori from Kagerou Days. Probably different with the real story. So... Yeah... Despite the names it goes to Vocaloid section. This is my interpretation to the song, and I don't like how I write the ending. Anon approved it though...

Well... please give me your opinion.

On to the story.

Hibiya

It was around twelve-thirty according to the numbers on the iPhone.

Hibiya looked up to the cloudless summer sky and grumbled a bit as he wiped the sweat on his forehead. He was sitting on one of the swings in the park, and next to him was his childhood friend petting a cat.

"... Why did you bring him here again?"

"Poor Neko-chan is lonely at home, that's why! Aren't you, Neko-chan? Aren't you? Hehehe, Neko-chan, you're so cute!"

The brunette sighed as he put his iPhone onto his pocket.

He wondered why he bothered asking.

It was Hiyori, after all. She's so clumsy, and ditzy, and childish... she'd do anything without second thought, and for the silliest reason too. Normally at school, Hibiya couldn't stand being near the overly cheerful girl.

But even so, she's the person closest to him, and everyone knew.

That's why that day on August 15, he decided to spend his day on the park with Hiyori.

"Hey, Hibiya. You've done your homework, right? Let me copy yours later okay?"

"... No. I'll help, but do it yourself."

"You're so stingy! Come on. At least the math?"

"No."

"Meanie."

"You shouldn't spend your holiday playing all the time, Hiyori. Do your homework yourself like all students."

The girl pouted.

"It's not like I've done nothing but playing..."

"Please... It's your favorite time of the year. I've known you for years now, Hiyori. You love to play under the sun the most."

Hiyori didn't respond for a while, and when she did the answer surprised Hibiya a bit.

"... I hate summer."

Hibiya thought he knew Hiyori the most.

He looked to his side, and Hiyori's face looked almost as if he had said something terribly bad about herself. Feeling a bit bad, he was about to apologized when Hiyori suddenly laughed out loud and said that she was just messing with him.

Hibiya didn't have time to get mad as the cat on Hiyori lap jumped out of surprise from her earlier outburst and ran towards the park gate. Hiyori ran after it immediately.

He planned to wait for her at first, but finally decided to follow after her. After all, it was Hiyori. She's so prone to accidents due to her clumsiness.

The cat had crossed the street, and Hiyori was running after it.

The light was blinking, it will soon turn into red.

Realizing that, Hibiya started to run.

"Hiyori! Don't cross!"

She stopped on the middle of the zebra-crossing, her body turned a bit towards Hibiya who was still quite far away from her. She was probably wanted to answer to his words, to say that nothing would happen even if she's few seconds late from crossing.

But alas, she couldn't.

When the light turned red split of second later, Hibiya couldn't see any colour other than red.

The sound of cicadas that he hated so much was for a very long second being drowned by the screaming of someone and the screeching sound of brakes from a truck that had appeared out of nowhere.

He stopped his legs from running and for a while he couldn't bring himself to take a breath.

Another second passed and he realized that the screaming voice he's hearing was his own voice.

He raised his hands to stop himself from screaming, and realized that he's being drenched in warm liquid which stench made him choke. When he realized that it was Hiyori's blood, he wished that it all was just a lie.

It was then when he first saw him.

A white haired boy (he sure looked childish enough despite his tall stature) with weird pattern tattooed on his cheek, staring at him and Hiyori's red unmoving body with dull red eyes.

Hibiya could hear the boy muttered "it's not a lie" as if he could read his mind before blacking out.

Before he lost consciousness, Hibiya was sure he heard him laughing.

When he woke up, Hibiya was still on his bed and he could only see darkness from the window. It was midnight, he realized after looking at the clock on his iPhone screen. It was the time between two days, and on his dazed state Hibiya wasn't sure what date it was.

"... I hate summer."

Hibiya already forgot what happened after he woke up, but Hiyori's words made him remember the events he saw before he woke up, the events he was sure happened in his dream.

Hiyori laughed after few moments of silent, surprising the cat on her lap which jumped and run towards the crossing. She ran after it immediately.

On the dream, he failed to stop her and she ended up getting hit by a truck.

Hibiya somehow could smell the stench of her blood and it made him so scared, he started sweating bullets.

He ran after her without second thoughts and managed to stop her.

Hiyori turned and apparently was about to scream in a rage at him, demanding why he stopped her from chasing her cat, but the sight of Hibiya sighing in relief, his face pale and sweaty as if he was sick stopped her.

"... Hibiya?"

"Let's go home."

"But... my cat..."

"I'll look for it later. Come on. I'm feeling bad."

Convinced that he was sick, she nodded and followed Hibiya to other side of the park. She knew that Hibiya was taking the long way towards their houses, but she didn't complain.

Hibiya was in a state where he couldn't be told what to do.

He couldn't even hear the voices of people around them, pointing their hands upwards as the machine Hiyori couldn't name on top of a skyscraper moved oddly.

Looking up, Hiyori could see metal poles falling towards the earth with frightening speed.

That's why...

Because Hibiya couldn't see that...

Hiyori tried to stop him by stopping right in front of him.

The boy looked confusedly at her face for a second, questioning the purpose of her doing, before the world was painted in red once more.

In front of him, Hiyori had been pierced by a pole.

And it was all his fault.

A heartbeat later, the sound of the poles hitting the ground like broken wind-chimes and the screams of the people around him drowned anything that could have been said by Hiyori.

Hibiya just stood there in a daze, drenched in warm liquid that's most certainly Hiyori's blood. The stench was as sickening as he remembered. On the ground, Hiyori muttered some inaudible words before stopped moving.

Hibiya was sure she was laughing a bit.

All in all, it was just like a nightmare.

"... no... Hi... Hiyori..."

Hibiya crouched down and with his trembling hand he took Hiyori's still warm hand. There was no pulse. Of course. The pole had pierced through her chest, and everyone knew that there was no way the small girl could survive. They all marveled at the unusual cause of death, none even care enough to call the ambulance.

"Some... Someone! Help Hiyori! Please!"

He started to scream at them, begging them to at least try to bring back her soul. His eyes were scanning the crowd as he desperately looked for someone who seemed care enough when he saw him once more, and his eyes widened.

It was a white haired young boy, his tall stature and weird style made him stand out in the crowd. He was looking down to him, again with his dull red eyes.

'… It's not a dream.'

Hibiya was sure he said that, despite the people's jumbled voices which made even his own screams hard to hear.

He wanted to ask him what he meant, but suddenly he felt his energy drained from him. The sensation brought him nausea and headache, and Hibiya could sense his consciousness slipping away.

He realized that he's about to pass out, just like in the dream. He closed his eyes, embracing the sensation as he vowed that if in the off-chance that it's all just a dream, he'd prevent Hiyori's death at all cost.

Just like before, the last thing he heard was the boy's laughing voice.

Opening his eyes, Hibiya found himself on his bed. Without looking at the clock, he knew it was midnight when the day had just turned into August 15, the darkness outside the window and the annoying sound of cicadas were enough as clues.

The white haired boy's words echoed on his head.

"... It's not... a dream..."

He couldn't go back to sleep like the day before.

He somehow knew that in twelve hours and thirty or so minutes, Hiyori would die, and if he fail to keep her alive, he'd repeat the day once more. They say after all, never two without three. He didn't want to check it, of course, but somehow he didn't doubt it.

More than anything, he feared for Hiyori's death.

She's been with him forever, and Hibiya was admittedly glad the day repeated before he could experience living without her. He didn't want to live in the world without her.

Hiyori was his... precious person. She's his best friend, although sometimes he thought of her as more than that. She was the one who brought light to his dull life... Without her, he wouldn't know what to do.

As soon as the sun rose, he rushed to Hiyori's house.

"... Uhm, Hibiya? What are you doing in my front door this early in the morning? Mom nearly called the police. She thought I'm being stalked by a bully."

Hiyori came out about an hour later at 7, holding her black cat.

"Go out with me."

Hearing his words, her face turned pale for few long seconds before her cheeks turned red.

"E... eh? I'm sorry, Hibiya, I think I misheard you. Can you please repeat what you just-"

"Accompany me this whole day."

Hearing his new sentence made Hiyori sighed and muttered something along the line of 'I should have known'. Hibiya would not suddenly gain interest in romance.

Not her overly serious geeky Hibiya.

Even so, in the end she smiled and nodded, even though Hibiya wondered if she's reluctant about it. Her eyebrows were furrowed a bit.

"... I'll treat you ice-cream later. Thanks, Hiyori."

"No prob. So, how about going to the park?"

"NO!"

Hibiya didn't know how he looked in her eyes. Hiyori looked so frightened, it was as if she had just seen a ghost. Her Neko-chan screeched at him. Hibiya took a step back.

He... must had been scary. Hiyori couldn't have known about the accidents that could kill her if she went to the park.

He took a deep breath and he felt a bit calmer.

"... I'm sorry. I... I'm just not in the mood for the park right now..."

"Oh... I see... So, where do you want to go?"

"It's summer after all. How about we go to the pool or something?"

She looked at him worriedly for a second before nodding. Hibiya then told her when and where to meet, and suddenly it felt as if his burden had just been lifted.

Hibiya somehow felt as if this time everything would turn out okay.

He hadn't realized how wrong he was.

This event in the morning was about to be repeated for hundreds of times.

When they went to the pool, Hiyori drowned.

When they went to the skating rink, Hiyori fell and got her neck cut by another skater's shoes.

When they went to the mall, Hiyori fell from the top floor.

When they went to the zoo, Hiyori somehow fell down to the hyena den.

When they went to the hill, Hiyori tripped and her head hit a rock.

When they went to the beach, Hiyori got drifted away and found in the end dead.

When he took her to a restaurant, Hiyori somehow got poisoned and died.

When he decided to keep her at home, Hiyori fell down the stairs.

When he decided to keep her away from second floor, Hiyori tripped when she's preparing his snack and ended up with a knife on her chest.

When he took her to his house, Hiyori got electrocuted when she's playing games with Hibiya.

When he decided to not meet up with Hiyori at all, at noon his parents would tell him that she's dead and he repeated the day after seeing her already cold body without knowing why she died.

There were many cases, Hibiya admittedly couldn't mention them all. It was as if a death god was following her around.

But in each and every cases, he remembered two things in common, Hiyori's dead body in front of him and the sound of laughter he's sure to come from the white haired boy.

After a while, he started to wonder if the boy was the death god.

August 15 had repeated so many times, Hibiya had lost count. It felt like years already passed. Needless to say, he's tired. His still young mind couldn't stand the stress of repeating hell.

And... that's when he realized that he's been doing things wrongly.

That day, he let her choose any place she wanted, and as expected she picked the park. He just watched as she played with her cat, laughing happily for the silliest reason like always. When he realized it, Hibiya found himself in the same situation as it was in the past.

He ran after her, and saw from the corner of his eyes the same white haired boy standing near the gate. In front of him, the green light blinked, signaling that it'd turn red in a second. Hibiya knew that a truck would come and slammed into Hiyori's body. If the white haired boy was really a death god, he'd surely say that Hiyori's destined to die at that time and day.

But he wouldn't let it happen.

Hibiya gritted his teeth and forced his legs to run faster. When she's within reach, he grabbed her hand and pulled her with all his strength.

He saw her stumbled, but away from danger and for some reason that moment felt so satisfying he couldn't help but to smile.

It was wrong to try to keep her away from death. What was right was to take her place.

Hibiya surrendered himself to gravity as what he did earlier led him to the middle of the zebra-crossing, and just as expected the truck slammed into his body.

A second could felt like a lifetime. It happened so fast yet so long for Hibiya. It was as if time didn't move at all. He saw Hiyori on the pavement, standing with weird position as she tried to keep herself from falling, staring confusedly at him. He could see her eyes widened in slow motion, even though in reality not a second had passed yet since he pulled her from the crossing.

Behind her was the white haired boy, his red eyes hidden under his bangs.

"... take that."

'With this... Hiyori is saved... You can't take her...'

Hibiya was sure the tall boy heard him, but his expression didn't change. Even so, at that time, the sound of laughter couldn't be heard. He just stood there, watching with half-closed eyes. Realizing that, Hibiya felt a sense of relief. If he laughed, then it'd be just like the usual summer days, and he'd have to repeat it once more.

True to his thought, the loop ended with Hiyori's survival.

Even so... for time to start moving again, it had to be paid with his life.

But, somehow Hibiya didn't regret it.
