At first I was thinking of rating this 2/5 for the MTL, the grindy gameplay, the annoying dungeon mazes where you keep running around looking for the exit, the on-defeat scenes not playing at all sometimes, and the large ammount of non-animated H-scenes, like ~80%, but I decided to rate this game a 4/5.
The story(spoilers):
A female knight and her sister who is a mage traver to a kingdom to investigate a dungeon with demons spawning. They meet the mayor and do quests for him, but the mage gets captured because the mayor is an evil bastard, and so are the guards. The knight rushes to save the mage, but the mayor threatens to gangrape the mage, so the knight is blackmailed into following the mayor's orders, with his horribly perverted plans. They command both of them to dive into the dungeon, locate a tribe's village and burn it to the ground, but the knight has already been there and she decides to warn the villagers that an army of pyromaniacs is coming to destroy the village, during all of this time the knight and the mage are escorted and sexually abused by 2 male guards, the mage had a lewd crest placed on her when she was captured, meaning that she needs sex to stop the pain between her legs, this makes the knight feel very depressed because the knight really cared for the mage, and hates seeing the mage get corrupted like this, so after the village is set on fire, it's a very tragic and sad moment, luckily the villagers evacuated to safety, as the fires burn the village, the 2 guards fucking the mage yet again because she literally asked for it, then a spirit appears, takes the mage into an alternate universe and murders the two guards. Feeling despair and hopelessness at the loss of the mage, the knight crumbles to the ground in sadness, as the fires buf around her, suddenly she is teleported to the same alternate universe, and she finds the spirit that did this, she explains that she is the spirit of a powerful mage that lvied in this village she saved, she took the mage away to protect her because only she can open the path to the demon king at the center of the dungeon, and she explains that shee needs the knight's help, without any other choice she agrees to help, but the spirit isn't very specific what exactly she should do, and then the spirit sends her with the clothes and appearance of her village's people back in time to the beginning of the game. Now you, the knight, follow yourself, but as a poor disgusting villager, you try to fight yourself from the past and warn them not to enter the city, but that doesn't work, you are kicked out of the nice neightbourhood and you are kicked into the slums, you never lose hope and desperately try to figure out how to reach the mayor's castle and save the mage before it's too late and she gets the lewd crest placed on her after getting sexually assaulted by the guards. You can either farm 200 000 gold to buy a fake prostitute pass and sneak in the mayor's castle, which is absurd, or become the highest-level prostitute by earning your rank in the slums' brothel and sneak in the castle normally.
Despite becoming the most horny prostitute in the city, the knight doesn't get mentally corrupted, or sad, the only think keeping her sane is the thought of saving her sister before it's too late. So eventually she manages to sneak in the castle, and right as the knight from the past is confronting the mayor, right before the guards start fucking the mage, the future-you jumps from the roof on the guard, knocking him down and saving the mage, at which point the past-you asks the future-you, what's happening, you quickly explain "I am you", you merge your soul with the past-you and now with your sister saved at the last moment, you and the mage attack the mayor. You win the fight, but the mayor runs away into the dungeon with his magical powers, Now with the mage safe, you explain what happened in the past, and feel very very happy for saving your sister, the mage. Now you head back in the dungeon, you use some statues with the mage to travel to the alternate dimension, you use the mage to open the lowest dungeon and there you find the demon king, now transformed into a hideous magic casting monster, you fight and defeat him, he is the final boss. And then you get the ending, it's a bit absurd, but at least order will be restored to the city some day.
Combat:
So, there's 2 parts to the combat from the story, there's the knight/mage combat and then there's the future-you sex-only seduction dungeon combat to reach the highest prostitute rank. It's a very nice idea for an H-game. The final boss is really tough, you just gotta play perfectly and you will survive on the edge, it's a nice challenge. Oh yeah, if it wasn't obvious, save often, there aren't any auto saves, at all. A nice quality of life change they added is you can open the menu and consult yourself to see what is the next objective, so you never get lost, very useful.
Oh yeah, also, an RPG? I never went to a shop to get neither armor, nor weapons, nor potions, nor upgrades, nor anything, fighting dungeon enemies gives you everything you need. There isn't really anything RPG in this game.
Alternate endings? Pffffff haha, there's only one alternate ending, where you just, abandon the mage and try to escape the city, but you get cornered and raped, even if you win the fight, the end.
The normal ending sees you become the mayor and sign a contract to be a free prostitute for ~100 people once a month as a form of reparrations while a new good mayor arrives later, lmfaooooooooooooooo.
As I already said, the grind, the maze levels making you get lost, and the horrible lack of animations in H-scenes most of the time is why this is a 4/5 for me. The H-scenes from the brother and from combat are exactly the same, and they are so repetitive. The concept of saving your close friend from evil perverted people is very simmillar to another game - Lilitales, but Lilitales I rate a 5/5, it's just BETTER.
