The development of scientific civilization stalled in the second half of the twenty-first century.

In Japan, the majority of former gang organizations were extinguished, and instead a new type of criminal organization became disturbed and the back society became huge, making illegal businesses of various genres one specialist per organization.

The size of the back society swelled to what could be called one of the country's important industries, half acquiesced by the government, and the name 'Backstreet' became entrenched and fearful.

From those who live their lives clean, right and serious, things from distant worlds that are unrealistic, such as the existence of backstreets, or objects subject to fear, but from those who are not, they are viewed in a completely different way.

And there are not only clean, right and serious people in the world.

"Ten nights, let's fall into the back streets."

Shibuya Ten Nights turned his eyes round to the first voice of his best friend, Yunzuka, who came all the way from the class next door during his lunch break.

"School is boring, study for exams is ridiculous, I became a Lehman and lived normally and died normally - or I'm just relieved to think about it. You're the same. You don't have to tell me. All right, that's settled. Let's do that. Let's go home. Go home. GO to a world full of excitement and enchantment of death and neighbourhood!

A shake trying to get him to take his sitting ten night arm and stand up as he swept it all over at once with a tall voice that resonated in every corner of the classroom. The surrounding gaze gathers for ten nights and shakes.

Always expressive and affectionate, with a clear noticeable nose and impressive large eyes and long eyelashes, the appearance alone stands out. Many women think of it, in addition to their bizarre words and behaviors from day to day attract more attention, making them well-known students on a grade-by-year basis.

This dialogue may also be seen as one of the usual oddities, but the way we received the ten nights was different.

"Wait a minute..."

The intensity of shaking is every time, and for the most part it is ten nights of following without surprise, but only this time I was bewildered by boulders.

"We're still in the middle two. You can't live in such a shitty world."

The growing number of teenagers falling in the back streets has become a social problem and is frequently eliminated in the news. The story is that the police are also harshly eyed.

Shaking has frequently mentioned backstreet topics so far, and I enjoyed it for ten nights, but I never seriously thought about throwing myself in the backstreet.

"The legendary senior Aizawa also said it was Nakaji who fell into the back street. Most people who fall in the back streets don't talk about teenagers. We can do it. That doesn't mean it's special. Oh, be ready."

In Euthanasia II, where ten nights and shaking pass, a legend was told.

Five years ago, the untouchable defect named Makoto Aizawa was in this euthanasia II, but he was tired of his bad life, fell into the back streets in search of stimulation, and said he was gorgeously active as the exclusive killer of the infamous Mad Scientist Junko Suzuoka.

Exploring the backstreet related sites on the internet, you can see several unrealistic anecdotes that have crushed criminal organizations, but have killed more than twenty people alone and all of them.

"Senior Aizawa seems to have been unusual since he was on the street, like he turned it into a bad total lamb all over Tokyo or haremmed the school, and I don't know if I can compare it..."

"Me, all I want to do is be funny, but I don't think you can find it funny anymore. Awesome boring. Everything is boring. I want to die boring."

A shake that looks at me ten nights in hesitation and speaks with a rare and true face.

"If you ask me what I live for, I live for fun. I don't want to do anything that isn't fun or interesting. I never want to. I don't want to die. You know, you have to do hard and painful things to live, that's ridiculous, right? Yeah, it's fundamentally stupid. But if you lived on the street, you'd have such a stupid boring life. You don't have to live that stupid way if you're on the back street, do you? It's always a hard world exposed to death, but that's why you can enjoy it. I'm sure I'll feel worthy of living. If the ten nights don't come, I'll fall alone."

Ten nights on the last word made me stronger.

The fear that the wobble, which has been acting together for nearly a decade, will put itself down and go somewhere. In the darkness, I see myself left in total solitude floating behind my brain.

"No... if shaking is what you mean, I'll go too. Just... anxious..."

As usual, I don't have a choice. Just follow the shaking decision for ten nights. Even in stories that don't even depend on life or death in life, such as falling in the back streets, that doesn't change.

If I add, I was thinking of a daily escape that could threaten my father's domestic violence for ten nights.

I didn't even go to high school, so much so that I decided to leave home and work. If I were to fall in the back street, I might be able to escape that house without waiting for my secondary school graduation.

"So, what exactly do we do?

"Oh, will you come ten nights after all? That's ten nights. Actually, about the back street, I've been previewing this. I hear there's a lot of work behind it. Illegal drug manufacturing and sales, human trafficking, arms and weapons smuggling, escorts, wholesale specializing in nasty bumps, hauliers, informers, end-of-life shops, and so much more. So, like the old Yakuza and overseas mafias, one organization is not doing this widely, but the industry is completely determined by the organization. That's why you can choose the job you like. Oh, it seems like only the doorman would do a lot of things as an exception."

Shake to explain quickly and happily. The earth is loud, so I couldn't help but worry about the sound of it all over the class for ten nights.

"If you're going to do it, I'd like a doomsday. Yeah, that's good. Take on the trouble, whatever you call it. Even comics are a lot of crap. Actually, I've already talked to the tissue in that hand in advance."

I heard you were already talking, and the boulder rolled your tongue ten nights saying it was a shake. This behavior makes me wonder if even one of these guys at the moment would be enough to do it in the back street.

"Are you serious? Aren't you going to freak out and run back anyway?

One of the defects, which had inadvertently solidified in the rear of the class, came in tea. I didn't try to touch any of the other defects because the shaking story was so flimsy, but only one person seemed to have the ability to help out a little bit.

Shaking looks back at the Lord of the Voice, grinning and lovingly laughing.

Shortly afterwards, a tremendous sound echoed, and the heart of everyone in the classroom except the shake jumped loudly at the same time.

"I bought this in advance, too."

A shake with a gun in one hand makes me laugh prank-like with my face toward the one of the ten nights. Nitrous smoke drifts from the gunpoint. The bullet wore a floor at the foot of the defect. The defect is stiff with a pulled face.

"You know, I didn't hear you very well, so could you say it again?

A shake that speaks out in a blatant tone, keeping the muzzle pointed at the defective with the tea in it. The defect was just smacking his teeth heels and shaking his neck sideways with a crying face.

"Oh, I'm buying ten nights' worth of course. Yes."

"Hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey, hey.

One more gun out of the nostalgia, it was a shake to offer to the ten nights, but the ten nights don't turn much of the confusion, and I wave and refuse.

"Oh, would it be a hassle if they called me in? All right, let's keep moving."

Telling her with a proper smile, Shake takes her hand for ten nights and takes her out of the classroom quickly. Ten nights just follow it.

It has always been, and it must always be, even if we went out of the routine and into the unusual world of back streets, etc., we didn't believe and suspect then that the path we would walk would always be the same.
