Nightmare x Vampire: Inferno of Retribution

The other world is on the verge of ruin, and there’s only one way to save it… the princess needs an heir. There’s just one problem — there are no men to give it to her! That’s where I come in, whether I like it or now. I’ve been summoned to this world to save it from a horrible fate…

Shonan Saika Academy, a high-achieving all-girls school in Kanagawa Prefecture.

One day, Marin Tachibana, along with her best friends Mashiro Saotome and Kiyoka Jinguji, experiences a special day.

It begins with meeting an unusual new transfer student, Shizuku Kujyo.

A beautiful girl with a calm and dignified demeanor.

Meeting her feels like déjà vu...

While showing her around the school, they stop by an observation deck, where Marin finds a four-leaf clover.

There is a tradition at this school:

If you press a four-leaf clover found on the observation deck into your student notebook, your wish will come true.

(I want to get closer to her. To spend more time with her...)

With this wish, Marin gives Shizuku the "coincidental" four-leaf clover she found.

This act becomes a turning point, bringing Marin and Shizuku closer together with the help of Mashiro and Kiyoka. However...

"Please, stop worrying about me. I don't want to just be protected..."

"Shizuku, we're friends, right?"

A storm threatens to tear them apart.

It is deeply tied to a "secret" Shizuku is hiding and a "trauma" from Marin's past.

The story follows the growth, mutual support, and cherished memories of the four girls.

Will Marin and the others find their personal "clover" (happiness)?

As a reserved and unassuming university student in snow-bitten Hokkaido, the personal tragedy which visited Honoka Asakawa would lead to her experimentation in a magical art thought long-lost — blood magic. Unexpectedly able to visit the sealed world of Meiji-era Sapporo, Honoka's quickly taken under the wing of the cheerful and bright Lady Yasue, a powerful mage who's remained in this gilded cage for a century.
 
As their feelings for each other develop, the true repercussions of Honoka's first steps into the secret world of magic and mages are only just starting to play out, eventually leading to catastrophic consequences.

In this game, you play as Fujita Hiroyuki, a high-school student who seems to have more interest in romance than in his studies. In his school there are several pretty girls, and his goal is to be nice to one of them, to make the right decisions when talking to her, and ultimately to win her heart.
