Hello there. Today I'm introducing "【Smartphone Ver.】 Cursed Island ~Once You're Bitten, It's All Over~."

There's something uniquely magnetic about the word "isolated island," isn't there? A place cut off from everyday life, with nowhere to run—just imagining what might happen there sends a chill down your spine. Created by the circle "Hige to deko," this title packs all the terror and excitement of an island survival scenario into every inch of your smartphone screen.

The story begins with a perfectly ordinary setup: a training camp. The members of the Occult Research Club have chosen a peculiar isolated island as their retreat destination. After a long voyage, what awaits the girls upon arrival is a horde of monsters bearing massive fangs. In an instant, normalcy shatters. Friends and companions scatter in every direction. The question "Can we escape this island?" weighs heavily on the player's mind as the story opens with a tension-filled prologue.

One of the game's greatest strengths is its cast of four distinctive heroines. The protagonist, Mizuha Tsukishima, is a kendo club member with a cool, strong-willed personality. Her line "If you come any closer... I'll cut you down!" perfectly embodies who she is. Her best friend, Mayu Shinonome, is an Occult Club member—a cheerful, earnest girl who keeps everyone's spirits up. The banter between her and Mizuha is a genuine pleasure to follow. Rui Hizaki carries an air of mystery about her; a woman who joined them on the same boat, she speaks little and keeps others at arm's length. She seems to have come to the island with her own agenda, and how her secrets weave into the narrative is a compelling thread throughout. Then there's Sara Hyodo, an archaeologist—a half-Japanese woman who came to the island to investigate its ruins. Free-spirited by nature, but push her too far and her karate black belt makes itself known. She's equal parts reliable and endearing. Watching how these four women—each carrying their own motives and backstories—navigate the same crisis together provides a deeply engaging character-driven experience.

The genre centers on a female protagonist and features themes of restraint, confinement, and trance/suggestion, with carefully depicted scenarios involving mind control, training, and captivity. The range of situations includes:

• Sexual harassment
• Brainwashing (hypnosis)
• Training
• Captivity
• Lewd massage
• Choking
• Biting

—a remarkably varied lineup. Since the game also includes ryona elements such as choking and biting, those who are sensitive to such content may want to check beforehand. For fans of darker themes, it's worth noting that the circle themselves have stated that "this title contains more extreme content than our previous works."

The sheer volume of adult content is another highlight that shouldn't be overlooked. The game boasts 48 base CGs (excluding standing illustrations) and over 150 scenes—an impressive amount of content. With 150+ scenes, you'll find yourself continually surprised thinking "there's even more?" as you play. The combat sections feature simple, action-style gameplay that's accessible even for those who aren't great with complex controls. The convenience of being able to launch it instantly on your smartphone, combined with the depth of its story and scene count, is perhaps a unique advantage of the smartphone game format.

With 143 copies sold, it's clear that the game's unique isolated island survival setting and its cast of compelling heroines have found a dedicated audience. The weighty array of scenarios—incorporating elements like drugs, ropes, and candles—intertwines with the white-knuckle tension of survival, creating an experience you won't be able to look away from until the very end.

Once you're bitten, it's all over—as that title echoes and slowly takes hold in your mind, why not see the ending for yourself with your own hands? The nights on that cursed island may linger in your memory for quite some time.
