A Lifetime of Complications with My Sister

"Let's Protect Deep Sea Tech City Together, Okay?"

"The Stranger"

Some say that beyond the deep sea lies an endless, dark abyss.

Technology seems capable of anything, but who knows that someone in the real world is struggling desperately to make it through?

Some predict that humanity will bring about its own destruction in the future.

So they created humanity's last hope: Deep Sea Tech City.

Within the city are the technology-worshipping fanatics of the Heart of Flame, as well as the Orthodox Star Hall, whose members uphold tradition and refuse to compromise with technology.

Though their beliefs differ, both organizations protect Deep Sea Tech City.

But no one knows when humanity will escape the threat of extinction.

An unremarkable brother and sister accidentally protect humanity's hope.

They don't want to be part of this world-shaking conflict. They're just ordinary people.

They were born ordinary, and all they want is to live out their lives in peace.

Yet, by chance, each becomes the strongest member of one of the two factions: the Heart of Flame and the Orthodox Star Hall.

With such different beliefs, they should loathe each other. Why, then, do they cherish and understand one another?

Who first made the vow to protect the city together?

If they swore to protect it together, why did one journey into reincarnation while the other went to the underworld?

Reincarnation goes on, yet you and I remain strangers...

"Dreams of Reincarnation, How Many Lines of Tears?"

Tears flowed endlessly in a past life, and reincarnation brought more hardship.

In this life, let there be laughter. Whatever troubles tomorrow may bring, may there be... everlasting peace.

"How Many Strange Things in This World!"

These are ordinary stories about family, people, and society.

The most commonplace things can be terrifying when you think them through!

"Deep Sea Tech City"

In a future where technology is extraordinarily advanced, darkness is consuming humanity's last hope. How can people live happily?
