"Hey, Kou-chin. Sorry to bug you but, will you help me study?"

It was a Saturday. There was still a month of summer vacation to go. Due to complicated family circumstances, Kouta - "Kou-chin" - who lives alone meet Chieri - "Chi-chan" - a classmate of Kouta's at the conbini near his house.

Chi-chan oozed sex. Her big tits and lazily protruding ass were a distraction from whatever he was supposed to be helping her with. She had the kind of body that, if you sat behind her at school, your grades would plummet. Somehow or another she was renting her own place. Whether she had a sugar daddy or did the whole "paid date" scene, Kouta didn't know. There were rumors about her, though.

This ditzy kurogal was his benefactor for the summer. Kouta helped her study - though he could hardly focus - and as a bonus he was endlessly visually entertained. He knew Chi-chan had a boyfriend so...... well, he didn't torture himself with fantasies, but at the same time Chi-chan had a flirty, cockteasing way.

"Help me study, Kou-chiii~n. Take care of me and I'll take care of your chiiiiiin~"
...

The summer blue sky over a verdant mountain village.
Across endless rice fields as far as the eye can see,
A refreshing breeze blows through.

“Welcome home!!”

Kousuke comes home from studying at an art college in the city,
and there to welcome him are adorable and kind goddesses who love him dearly.

Feelings and emotions come together,
and grow like budding leaves
as this gentle and warm story begins. ...

In the year 20xx pregnancy has become a status symbol. Girls that are virgins are stupid, right?

On the first day at his new school, Hiroki is falsely accused of underwear stealing. While moping around on the way home, he picks up an unfamiliar game. When he tries playing, it seems to be just a trash game, but he's completely absorbed in it nevertheless.

The following day at school, he encounters the "White Lily Club", where young ladies get together, being ridiculed by some girls from another school for being inexperienced with males. And then suddenly:

"Looks like one of them is crying! What will you do?"
⇒ [Help] *beep*
　[Ignore]

It appears that he has been turned into some kind of "protagonist" in the real world. Nonetheless, after helping with their little problem, he is asked to join the club to teach them about males.

And thus he decides that, with skills accumulated from playing eroge, he will capture all the club members and build his own harem. ...

...Gods in heaven, demons on earth, and a giant floating continent for humans.

The continent that is known as the『Floating Continent of Yggdrasil』.

That is, a floating miniature garden of the gods.

A place where the human survivors of the great war live, the continent closest to the realm of the gods.

The Demon Emperor Surtr who has his eyes set on that continent said this to this heirs.

「The one who brings me the Heart of Yggdrasil said to be safeguarded by the goddesses on the Floating Continent of Yggdrasil shall be the heir to my throne. As long as you get your hands on the Heart of Yggdrasil, I will not question your methods nor your past transgressions. You are free to make alliances between yourselves, sabotage, or even 'remove' your fellow heirs as you would any obstacle. Kill and rampage as you wish and prove to me your strength and worth」

Hearing those words, Surtr's heirs, all having motivations of their own, began their invasion of the Floating Continent of Yggdrasil.



Among them, an ostracised member of the demon nobility, Loki, has also decided to participate in the feud for the throne.

To become the Demon Emperor is to stand above and at the very top of every demon.

If corrupting the goddesses said to be as beautiful and elegant as a flower in full bloom will be the key that leads to him gaining the throne, he saw no reason not to participate.

He, who desires the divine, beautiful goddesses.

He, who lusts for power to obtain everlasting freedom.

He, who wishes for the neck of the Demon Emperor who took everything from him.

5 invading demons, and 5 goddesses fighting back.

All the pieces have fallen into place. All that remains is for him to wager his own existence in this battle and fight.

In a continent caught in a whirlpool of chaos and ambition, Loki's own ambition burns brightly. ...

Nestled between the mountains and the ocean somewhere sits the harbor town of Inogo City, a prosperous place with an atmosphere of the exotic.
It is this city, watched over by the church at the summit of the highest mountain, where a boy and a girl first meet.

The boy's name is Kirinokojima Tomoe. A lonely young man, who believes neither in love nor in happiness.
The girl's name is Aine. One who sings of love to fill the world with happiness, who was born for that very purpose... an angel.

To anyone who saw him, Kirinokojima Tomoe would have seemed to lead a singularly boring life.

He didn't even attempt to befriend others, nor did he have a girlfriend, unsurprisingly. He was involved in no hobbies or interests to speak of.
Waking in the morning only to go off to school, returning home only to sleep. An utterly ordinary, routine life, each day no different from the day before or after it.

But he was not in the least unhappy with his life. For him, a life of "nothing" was also one of "nothing to lose".
Wish for something, and you would only end up getting hurt.
After all, he'd already sampled enough of the world's bitterness for one lifetime.

Until, like a herald of the end of that tranquil existence, an angel appeared.

"Angels". The protectors of human loves. The ones who spin the "red thread", and those who play its melody.

"Love can never bring people happiness.", said Tomoe.
"That's not true at all! Falling in love makes your heart feel all light!", Aine replied.

Tomoe, who soon found himself aiding the "acting angel" with whom he couldn't see eye to eye on anything in her work, is is drawn alongside Aine into deep involvement with others' romantic lives...
The many shapes of love, and the forms of happiness that pass before our eyes every day.
This is their journey to find the true meaning of happiness.
And at that journey's end, his own reason for living on... ...
