A girl blessed with immortal life and cursed with a cruel fate seeks a future for herself.

The protagonist lived in a world with a strict and ever present class system.
She was the slave of a deformed, vulgar master, and endured his mental and physical abuse each and every day.

However, she accidentally received eternal life from the king of their world, and was stripped of what little rights remained to her.

The people descended upon her with cruelty and malice.
They played with her, knowing that she could not die.
The protagonist wanted to be free of such an eternity, but could not even commit suicide...
However, someone told her that if she killed the king, she could also die. She attempted such a murder, failed, and had to escape from the town, her pursuers hot on her heels.

An unfathomable length of time would then pass in which she would meet other people and have to part from them, at times threatened by the pursuers the king had sent...

What future awaits someone who cannot die? This is the story of a girl cursed with that cruel fate. ...

The protagonist is having a hard time at work.

His superior, Kyouka, is a prideful woman with an arrogant attitude towards male employees. She especially dislikes the protagonist, so she's always making things difficult for him.

"You haven't finished the report yet!?"
"Haven't you learned anything in college!?"
"You are an adult, you have to be responsible!!"
"Geez...men are always making excuses, that's why I hate them!!"

But one day, the protagonist discovers a secret about Kyouka that will change everything. ...

Tsukikawa Shrine has become strangely infamous as a place that supposedly spreads misfortune - a rumor that Shizuki Yachiyo, the daughter of the head priest, is highly concerned about. When Ichitaro ends up living at the shrine for a while, he starts helping his childhood friend out on the job, and eventually, he realizes something.

While Yachiyo is a diligent, hard-working priestess, she doesn't actually seem to believe in the shrine's deities, or the effect of their charms, at all. She also doesn't smile as much as she used to, almost as if she's given up on all hope in life. Without any friends at school, she always appears to be rather lonely.

Then, one night...

Ichitaro wakes up sensing a strange presence, and finds Yachiyo perched on top of him, peering into his face. She looks almost like an entirely different person

"You know... I actually wish I could..."

The small priestess reveals to him her deepest feelings - her worries, and her hopes.
Now that she's opened up to him, and only him, Ichitaro feels like he must console her somehow.

"Dear gods, please tell me this is the right thing to do..."

"Yep!"

"...Huh?" ...

Hatori Yuu has a problem: his sex drive is so ridiculously strong it’s disrupting his day to day life. Yuu, however, has fallen head over heels for the kind and beautiful Kaori-sensei. Thanks to his raging libido, that means that just looking at her puts him at full mast in an instant.

He can only make so many excuses and run away so many times before Kaori-sensei finally gets suspicious and calls him out after school. Kaori-sensei takes his hand and tearfully explains that she just wants him to enjoy his school life, and that she’d do anything to help him.

Her damp eyes, her sweet fragrance, her sizable bust pressed against his knees, and her hand, gripping his… It’s the first time Yuu’s felt that much bodily contact and it overwhelms him.

And so begins their secretive school affair… ...

While she brushes off his approaches at first, her attitude toward Ichitaro changes after he offers his help when he finds her feeling unwell at the station one day.

"You don't need to be so formal with me..."

Soon after, he finds himself on the fast track toward a friendly relationship with her.Yet while she blushes and swoons at all his advances, she refuses to make things official and be his girlfriend.

All trains must eventually reach their destination, but where is Ichitaro and Nio's relationship headed...? ...
