About
Dr. Brian, the genius scientist behind the rediscovery of Crest Magic, dies in an accident under mysterious circumstances. Years later, Illumina, the man's only daughter, pursues the career of prison guard in order to gain access to Prison Island and investigate her father's death. Only those with magic affinity get to become guards though, and only men so far have displayed this quirk... But by some miracle and to everyone's surprise, Illumina is compatible, allowing her to become the first female prison guard in the whole nation!
And yet, as the only woman on an island full of men, things will only get more difficult for Illumina from here on out. The wardens rule with abandon and impunity, and their word is law... Will she be able to solve the mystery behind her father's death? And what will it cost her?
While Illumina has studied for years to become a prison guard, things don't work quite as the books said once she gets there. She'll have to navigate a hierarchy corrupted to the core and perform favors for guards and wardens in order to find the information she needs and uncover clues about her father's death.
Many of these favors involve combat, of course, but Illumina's brand-new magic crest comes in handy for that. Not only can she wield a powerful non-elemental spell that allows her to damage all kinds of enemies, but she's also an Omni-Spec, meaning she can wield each and every element... provided she can afford to get more powerful magic crests, that is!
Talk and fight your way through the various blocks of Prison Island while trying to keep your moral compass pointed north.


A Ruthless Tale
The story doesn't pull any punches, and neither do the guards and wardens of Prison Island. Corruption runs so deep it's inextricable from routine, and anyone with an ounce of power will use it to twist their neighbor's arm and get an advantage. As the latest and most naive hire, Illumina will have to sink low before she can rise high once more.
Rampant Prison Violence
Prison Island is a secluded archipelago penitentiary and home to many heinous criminals, but sometimes the inmates can be indistinguishable from those meant to keep an eye on them. All guards on Prison Islands wield powerful magic and don't hesitate to put it to use to torture and murder prisoners with utter impunity. The legacy of Illumina's father is being sullied every day.
Classic Elemental Combat
Fight your way through the various islands as you complete missions for the wardens, trying to garner their favor and stay afloat in this dog-eat-dog world. Rack up funds to afford new Magic Crests that will improve your arsenal and give you a chance against increasingly powerful foes. Master the elements and take advantage of weaknesses to come out on top and solve the mystery of Prison Island.

[b]"A game with a main character who is a prison guard, with huge tits and a huge Dic.... oh its a clitoris, but wait she can cast magic when she rubs it?... men from mine only comes out a useless white liquid when I rub it, maybe I should try a higher speed...."[/b] [h1] Review [/h1] Another of ONEONE1's re-released H-rpg games characterized by quite good art despite its original release date (2016) and highly loaded with sexual content in scenes with a variety of fetishes, both in the still scenes of events and in animated scenes in combat. Island of Penance faithful to the style of the developer has as the protagonist of the story a rather attractive and sensual woman with huge breasts, ass and a rather unconventional clitoris with the size of a Ðick, which is the search for the truth about the murder of his father, she gets to work as a guard in a prison that is divided into several islands, but to her misfortune she will soon end up humiliated, raped, defiled, stuffed and any other word that ends in ed and have sex in between, since she is the only woman in the prision and both guards, prisoners and monsters will end up using her as a sex toy, without her being able to do anything about it. The story of the game as such passes to a second plane as it is limited to the protagonist gradually discovering more information about her father and the experiments he did, as she completes missions for the head of the prison, and the rest of the story consists of the constant humiliation and harassment she suffers, due to her attractiveness and the fact that she has to go almost naked because of the crest on her clitoris and following this pattern to the end, because even though the game is from oneone1 this doesn't have alternate routes like purity or other alternative, similar to the subsequent games, so this one ends up being linear, with the only option of full corruption. The gameplay is the most basic of any other rpg, turn-based combat, equipment, levels, magics, physical attacks crossing dungeons full of monsters and defeating them in order to complete quests,nothing out of the ordinary, only the fact that the protagonist does magic with his clitoris and a crest that he was tattooed and which you have to improve to acquire more variety of magics, The game shows its antiquity by requiring a lot of farmings weapons, spells, accessories, etc. have quite high prices and are necessary to buy to overcome the bosses of the area, although true to the genre, you can also get money with prostitution. Graphically the game looks like any other rpg maker title as it uses generic enemy sprites and cities, but in terms of the art of the protagonist this is excellent, combining a defined and proportionate body, with quite lewd and revealing outfits. In terms of sound, the game offers decent background music and sound effects, but what is surprising is that the dialogues of the protagonist have Japanese voice acting for most of them, so thanks to this you can establish the personality of the protagonist and notice how it changes as she falls into the pit of lust. 🔞[b]sexual content[/b] [b]-You Need to install the external patch from the publisher website[/b] *if you need help with this, you can add me to ask me about the patch* True to the style of oneone1 the game contains a lot of sexual content from the beginning of the game, starting with the revealing and almost naked attire of the protagonist, followed by the multiple sexual events of harassment, with groping to which the protagonist is subjected, in addition to the non-consensual sex scenes, which are mostly simple, being still and with little variety of CG to give them movement but with an excellent art quite lewd and uncensored, and accompanied by dialogues with voice acting and sound effects to give more intensity to the scenes. The game also has another type of sexual content, which consists of short sex animations that occur during combat and in which the protagonist is raped by enemies, these animations have a lower drawing quality than CG, but help to give variety to the sexual content of the game, almost any enemy has a sexual attack animation so there is also a wide variety of these to enjoy. The game despite being an h-rpg with combat does not have scenes of defeat, if not all the sex scenes are unlocked by talking to characters and have a heart, or in story events so it is important to explore the prison to talk to all the characters and unlock the scenes. A highlight of the sexual content of the game, is the wide variety of sexual fetishes that includes, highlighting the non-consensual sex, orgies, gangbangs, creampie, etc, but also includes other fetishes more Japanese as sex with other species, tentacles, pregnancy, lactation, and even other fetishes stronger than can become unpleasant to some people as: urine, deformation of the belly and scenes of childbirth. 💭[b]Conclusion[/b] The game is pretty decent, despite having quite a few years since it was first released (2016), the game has a story of generic corruption and standard rpg gameplay with a touch of exploration and extensive farming, but certainly the biggest attraction of the game is its sexual content, which abounds in every part of this, including in combat, which even in current games is rare to see, so in terms of night material offers more than enough and high quality, even so the game has certain drawbacks due to its age and its engine, as the lack of visual aids, target book, dialog log, support for gameplay with mouse, etc. so if you are not used to old games you can spend a while uncomfortable playing the game with keyboard and getting lost in ocaciones without knowing where to go. As I say in most reviews of re-released oneone1 games, the game lets you see the basics of current games almost perfect that makes the developer today, has pretty good ideas but unpolished and can be difficult for a player accustomed to the current hentai games enjoy it 100%, but if you are one of those classic rpg game lovers and want to see a protagonist in a sensual guard outfit being harassed and defiled by prisoners and you already played Karryn's Prison, this game is also a decent choice.

Island of Penance? Uncovering Truths in a World of Shadows! (ฅ'ω'ฅ) "Island of Penance blends classic RPG elements with a dark narrative, presenting a unique exploration of moral ambiguity." [h1][b][1] Intro : [/b][/h1] Island of Penance plunges players into the murky depths of a notorious prison island, where Illumina, driven by doubts about her father’s death, takes up the role of a prison guard. This action-RPG mixes traditional combat mechanics with a deep, corruption-riddled storyline. Illumina must navigate a morally compromised hierarchy, using both combat and her unique Omni-Spec magical abilities to unravel the mysteries surrounding her father's death. The game challenges players to maintain their moral compass in an environment where corruption and violence are everyday realities. [h1][b][2] Game Experience : [/b][/h1] (1) Pros: - Engaging Storyline: The narrative is compelling, with Illumina’s quest for truth adding a personal stake that drives the game forward. - Dynamic Combat System: The use of Magic Crests to harness various elemental powers adds depth to battles, requiring strategic thinking to exploit enemy weaknesses. - Unique Setting: The prison island serves as a gritty, immersive backdrop that enhances the game’s dark themes. (2) Cons: - Linear Gameplay: Some players may find the game’s progression too rigid, lacking the flexibility and openness preferred in modern RPGs. - Outdated Mechanics: Despite its unique premise, the game struggles with an outdated engine and lack of support for modern conveniences like mouse gameplay, making it less accessible to new players or those accustomed to more contemporary interfaces. (3) Community Feedback: - Mixed reviews highlight a division in player reception, with criticisms focusing on the game's linear story and sometimes tedious combat. However, fans of classic RPGs and those who appreciate a more adult narrative in games have found it engaging. [h2][b][3] Final Thoughts : [/b][/h2] Island of Penance offers a dark, thought-provoking experience wrapped in the trappings of a classic RPG. Its ambitious blend of narrative depth and moral exploration is worth noting, though it may not resonate with every player due to its linear storytelling and mature content. For those intrigued by a tale of corruption and redemption, and who can navigate its older gameplay mechanics, Island of Penance could be a captivating journey. Those interested in a complex narrative with mature themes should consider giving it a try, keeping in mind both its potential and its limitations. [h2][b][4] Side Note : Nyanco Channel?

作为狗叫社(ONEONE1)老粉丝,从冲突的意志开始喜欢上这家社团的作品,购买本作并且游玩之前并不知道这款堪称远古级作品 ,在花了大十几个小时后终于通关本作,简直是一次折磨 首先: 1)CG不算太丰富,题材姿势千篇一律,然后就是CG重复出现率太高,导致新鲜感本来就不算高的情况,最后让人烦躁 2)战斗系统和地图设计一塌糊涂,战斗繁琐不堪,地图也到处是死路和无穷无尽的小怪,升级还非常慢要升级还必须要去刷,说实话,13个小时游玩时间,可以说10个小时全是刷怪升级 3)剧情毫无吸引力,与狗叫社成功大卖的作品相比简直是天上与地下 最后,没想到我目前为止我玩过的RPGMAKER类游戏里玩得最难受,可以说是我玩过的RPG最差的游戏竟然出自狗叫社 不知道神乐为什么现在才推出这么老的作品,但是后几作又被白舟抢去发行成有马赛克的版本了,这几作才是应该是神乐去争取去代理发行无修版才对,本身让我很生气 但是狗叫社目前为止叛道武士之后的新作最新作魔女神乐终于抢下来发行了,期待还是很期待的,也会继续支持的,毕竟是“真”狗叫社的作品。完全体和幼年期狗叫社毕竟还是没法比的,本作的问题在之后应该都优化了很多 神乐发展到现在一路走来,从原来发行的作作精品好评,到前两年开始出现几款中评作品,到现在经常出现褒贬不一的作品,有爆款才代理发行,不知道现在是什么标准去选择发行游戏的,真的是一言难尽 现在代理日系HGAME的发行商也雨后春笋般出现,也算填补了些精品游戏的空缺,想当初这都应该是神乐该出的,算万幸还是不幸呢? 魔女复仇之夜,圣骑士丽卡等等,争取发行这些神作才是主业呀,哎
I normally love Kagura Games products but not this one. The art was alright until we got to the snu snu parts. That hot dog that slipped out of the bun is too much for me. If you like futas, you'll probably like this one. I don't like futas so, I don't like this one.
Usually I have something nice to say... Forced small resolution, no sound design, and unappealing characters.
It is an ok game. The story is way to linear for my liking, and the lewds are not the best. It is a bit confusing about where to go and what to do next, but there is a guide here on Steam in foreign language with images that points to the next POI. I also didnt like the fighting, because everything just takes too much time. 6/10
IDK man this just isn't it for me. Combat is fine (it's a very boring implementation of normal turn-based combat), the art style is very generic RPG Maker stuff. The sex content is almost entirely non-con gangbangs, bestiality, torture, etc. And involves a lot of body shaming and physical abuse. At no point does the MC ever enjoy anything that's happening to her, which makes it tough. I'm all for corruption themes, but that doesn't really seem to be what the developer was going for here, instead it's more about the mind break. I got to the third of four chapters (at least what seemed to be four chapters) in just under 3 hours, and it didn't seem like it was going to get any better so I quit playing. I was kind of hoping this would be more like Karryn's Prison, Princess of Zeven, or something else in the theme of "woman is used indiscriminately by an island full of guys but she's into it so it's okay", but nope.
