Réserve (jp. レゼルブ) is a cute game about a girl who suddenly gets transported to a world full of monsters. It appears to have been the first product by the doujin group M.I.N., who would later become more established as the company Silence. The game was released in 1990, and has a very Ranma-esque artsyle.
Its sequel, Réserve 1/2, was released a year later. This time you play as one of the enemies, Batgal. The gameplay is largely the same, although this time there are encounters you'd absolutely want to avoid. The game is also a bit more polished than the previous entry. Unfortunately, it seems like the player character from the first game isn't here, but she is a major character in Réserve 2, released in 1992.
Mio, the main character, is preparing for a date with her boyfriend. On the way to her date, she ends up in a vortex and suddenly finds herself transported to a new world! You would think she'd be nervous, but she only seems inconvenienced, because of her date...
A small elf comes up to Mio and decides to warn her about the monsters of this world. It turns out that not only do the monsters have a taste for human girls, but they also like having sex with them. Mio has to navigate the world and fight monsters in order to go home unscathed, and make it to her date on time!
In the sequel, Batgal finds the other monsters gathering around and talking. When she asks what all the hubbub is about, she learns that humans have been popping up all over their world. She's excited to have fun with them, but then her friends reveal that Lord Satan has decided to give a reward to whoever will find three humans for him. Unsurprisingly, he, too, has a preference for girls...
The gameplay is pretty simple. Mio (represented by a star) travels through the map and encounters monsters at specific spots. When in battle, simply select the two correct answers to proceed. If you pick two wrong answers, however, the game ends and you're shown a porn graphic that's unique to the monster who defeated you.
The game is only a couple of minutes along, with any added time being due to misremembering the answers or a simple misinput. There are 20 enemies in total, but it's not required to beat even half of them. If you beat all of the enemies, you get a special code at the end to input in Kana mode, but I'll let you discover that for yourself...
The sequel's battle mechanics are the exact same, however there's added trouble. Beating a human means taking their essence—if you have even ONE male human's essence, Satan has no problem with taking you instead! Beating a human will show you a unique porn graphic, and some male characters have unique game-over screens, too. If there's nothing unique, you'll be found by the other monsters and have to start over.
Unlocking the special code is a lot easier in this game, since it just involves picking one option instead of the other. I'm not gonna just give it to you, though.
Want to see all the dialog options at the end, but don't have the brainpower to remember each enemy's weak points? Want to get the special code at the end but are having trouble getting past every enemy? You're in luck, because I've sat down and played through the whole thing like an insane person.
I've hidden it behind a button, so that you don't have to be 'spoiled' if you want to figure it all out for yourself.

I'm currently working on ripping the OST for both games. They seem to be in a common format (PMD .M file), but for some reason they're quite finicky...
I also have gameplay of both games available! Due to being hosted on YouTube, the pornographic content is censored, however I do my best to showcase as much of the game as I can. Take a look here:
M.I.N is probably one of their lesser-known areas (at least, by people who aren't super into PC-98 games. You may know M.I.N better as Sogna, one of the names they published under.
If that still doesn't ring a bell, here are a few games this group is responsible for:
Many of these games saw releases outside of the PC-98 platform, at least in part. Vision was also released on the Sharp-X68000.
