Succubus Runa and the Erotic Dungeon

At the Saint Michael Girls' School... festivities erupted among the girls of the annex. The reason for their celebration is the Best Couples poll being held at the main campus. The students at the annex, who look up to the girls from the main campus, decided, "Let's have our own Best Couples!"
...It was always inevitable.
And so, the fairest and most intimate couples were nominated...

The first couple is a pair of childhood friends, Misawa Nagisa and Takahata Rina. The second couple is a pair of twin sisters, Kimishima Ai and her younger sister Aya. And finally... The transfer student who saw this whole thing as no concern of hers, Onohara Hazuki, is shocked to hear that she too, was chosen to be among the Best Couples.

Moreover, her partner is the sheltered young debutante, Suoh Manami. Actually, Hazuki has secretly been crushing on the impeccable Manami... But the truth is, they're far from a couple, and while their classmates may cheer them on, it's all in vain.

But then... Hazuki works up all her courage to ask Manami to become a "Best Couple" with her, and...

A world where dragons have been hunted to extinction by humans.
The disciple of the master swordsman, Reiri, is still trapped in a nightmare from 15 years ago.
“A hometown turned to stone,” “A black dragon,” “A man playing the flute”…
Just as she had almost given up, thinking there was no way to find out the truth, she receives news that a “black dragon” has appeared.
Unable to stay here any longer, Reiri leaves her familiar home and sets out on a journey.
A journey to face fate, conspiracy, and herself…

One day, an island suddenly appeared in the sea about 100km east of the Kingdom of Greatland.
Some people land on the island, some by order of the country, some to investigate, and some just to check it out.
In the island, which quickly becomes crowded with people, one boy wakes up.
The boy, Riku, has lost his memory.
Wandering around without knowing anything, Riku meets
Sienna Clark, a nun apprentice, and Mira, a self-proclaimed archaeologist.
One of them is there to keep an eye on him, while the other is curious.
Thus, the party is complete, and they will explore the secrets of themselves and the island.
Will they resist or succumb to the difficulties that stand before them one after another?
The adventure begins, depending on their own choices!

The Infinite Sky. The Infinite Earth. A continent that embraced all the world.

At its heart lay the Elven Kingdom of Maradian—a land of abundance and blessings,
a place overflowing with dreams, compassion, love, and joy.

Yet, with the actions of a single traitor, Maradian was brought to ruin in a single night.

Barely escaping with her life, the second princess of Maradian, Artesia,
encountered a lone girl in the human realm.

Her name was Harukaze Sakura.

Was it fate, inescapable and binding?

Artesia entrusted her soul to Sakura,
and together they found themselves fighting against the pursuers from Maradian.

The pure-hearted girl’s soul resonated with Artesia,
and clad in armor born of their bond, she stood against the monstrous foes that pursued them.
