Lust Friend

You wake up in a fantasy world filled with succubi... and it isn't the first time this has happened to you. You encounter Fess, a whimsical blonde haired succubus who was an enemy in your previous adventure, and who is responsible for calling you here.

But this time around, Fess doesn't seem to be your enemy. She's currently building a tower for her kind, and says that if you help her finish the tower, she'll return you to your original world.

Lust Friend is a H-game released by company 62studio in 2019. It is a sequel to their previous work Lust Grimm, featuring the same main character in Magrut.

The game has a wiki, which is shared with Lust Grimm.

Tropes used in Lust Friend include:

Auto Revive: You get two free auto-revives each battle. The first one restores you to 50% of your maximum health, the second to a third of your maximum.
Battle Strip: You can do this with the Undress skill, and enemies automatically strip after taking some damage. This results in the Undress status effect, as noted under Full-Frontal Assault.
Becoming the Mask: Chloe, who was originally the succubus Manuve, has fully assumed this fake identity and become human. This was hinted at by a bonus scene in the previous game.
Buxom Is Better: As in the previous game, this trope could easily be an alternate name for the game. Almost every enemy has breasts that are as large or larger than her head, and said breasts are also usually the emphasis of the sex scenes.
Cute Monster Girl: They make up the entirety of enemies. While all of them are technically succubi, they include types normally used for non-succubus monster girls e.g. bee girls and cow girls.
Demoted to Extra: Many of the returning characters from Lust Grimm, namely Ideal, Chloe, Lust Reaper and Rotkäppchen, are much less important here.
Distracted by the Sexy: Several status ailments are this and these are occasionally inflicted by an enemy assuming a sexy pose.
Elemental Rock-Paper-Scissors: An unusual variant, fitting the nature of the game. The elements are body parts of enemies: Hand, Foot, Mouth, Chest, Ass, and Pussy. Each enemy is vulnerable to dealt to particular parts of their body (hands and feet aren't targeted by any of your attacks), conversely, their attacks use specific body parts.
Exclusively Evil: Subverted to an even greater extent than in the previous game. Not only are there more succubus NPCs who are friendly to the player, it is now possible to talk to enemies mid-battle and become friends with them, which instantly ends the battle and gives you unique items.
Final Boss Preview: You get your first glimpse of Shandilla just after you complete the first addition to the tower. Except that she's actually The Dragon to Empress... who still isn't the real Final Boss, that's actually Mea/Last Nightmare. It's still played straight in that you see Mea at several points prior to the final battle.
Full-Frontal Assault: Being naked is an actual status effect ("Undress"), increasing damage dealt and received and granting access to specific skills.
Grappling with Grappling Rules: Enemies can put you in a Hold, which lowers your damage, prevents you from fleeing and sometimes restricts other actions as well.
Healing Checkpoint: Unlike in the previous game, this is subverted - talking to a Record Keeper Fairy no longer heals you.
Horny Devils: These make up the entirety of enemies and, unlike the previous game, the majority of friendly NPCs as well.
I Just Want to Have Friends: This is Mea's primary motivation. Fittingly, the True End of the game requires you to befriend her.
Little Bit Beastly: The animal-based succubi tend towards this.
Improbable Weapon User: You equip books as weapons and this somehow raises your offensive stats, despite all combat being sexual in nature.
The Many Deaths of You: Like similar games, losing to an enemy results in them raping you to death. There are different endings for when you lose to an enemy for the first time compared to subsequent losses.
Multiple Endings:
- The Normal End involves you defeating the Big Bad Shandilla, except that she turns out to only be The Dragon to the real Big Bad, Empress. You don't even get the chance to fight Empress - she steals your body and forcibly ends the game. When you reload your save file, you are transported back to the beginning of the game..
- For the True Ending, you need to befriend every other enemy in the game as well as see all of Mea's events, then confront Empress again and befriend her as well (if you defeat her normally, you're briefly sent back to Earth and the succubus world is shown to be destroyed, then you get pulled back to the succubus world prior to the destruction so you can try again). After befriending Empress, Fess tries to send you back to Earth but you're instead pulled into a strange space with Mea, who transforms into Last Nightmare, the real Big Bad. You then need to talk to her until you can befriend Mea.
- There's also an ending inspired by the Genocide ending of Undertale. If you defeat enough enemies, you'll obtain an item that lets you kill them permanently. Do this enough, and you depopulate the world and eventually get drawn into a battle against Dark Fess. As in Undertale, this permanently affects the save file; in this case by preventing you from doing anything other than fighting Dark Fess (and seeing her associated H-scene).
Ninja Pirate Zombie Robot: Most enemies are some combination of a succubus with something else. Additionally, the succubus towns are naturally populated by succubi of many different professions.
Portal Network: There are various crystals around the world which, when you first find them, create a corresponding crystal just outside the first town. Interacting with a crystal lets you teleport to the other one in the pair.
Preexisting Encounters: Non-boss enemies walk around on the map and most pursue the player upon seeing them (a few follow preset paths), initiating battle on contact. All enemies have their level displayed above their heads, allowing you to choose whether you want to fight them or not.
Ridiculously-Fast Construction: The construction of new floors for Fess Tower: all you have to do is hand over materials and a new floor is constructed immediately. Subverted when it turns out that the tower was already complete, with your materials being used for a different purpose.
Sanity Meter: Returning from Lust Grimm is the Lust meter, which is displayed as a percentage. Lust is displayed as a percentage. It fills up when you escape from enemies, when you struggle but fail to escape from a hold, and occasionally when you're attacked. A higher Lust meter increases the damage you receive, causes enemies to hit multiple times with their attacks and use powerful special attacks, and reduces the chance of you escaping battle or escaping holds. It can be reduced by using certain items or by losing a battle.
Spiritual Successor: This game is very obviously inspired by Undertale: it has similar endings and you're encouraged to befriend enemies instead of defeating them.
Talking the Monster to Death: A new feature is the ability to talk to enemies during battle to befriend them. There are six different talk skills, each of which leads to a list of dialogue options (these vary slightly from enemy to enemy). Some options increase their opinion of you, others decrease it and others have no effect. Once you raise their liking of you enough, you get a "Friend Flag", depicted by these two words in the bottom left of the screen. This gives you the option to end the battle instantly. This is the only way to get a series of stat-raising items and befriending all enemies is required for the true ending.
Video Game Time: The game has a 24-hour day-night cycle as well as a cycle of four different types of days (each named for a colour). This affects what enemies spawn, how strong enemies are (they deal more damage at night than during the day) and what events are available.
Well-Intentioned Extremist: Empress. Her plan is to forcibly merge the human and succubus worlds, transforming the women into succubi and making the men their food, and she needs Magrut's body for this, but it's all for the sake of stopping the predicted destruction of the succubus world.
