An artificial island and vampire life
Aqua Eden is a special artificial island zone off Japan's coast, where casinos operate legally. Yuto Rokuren and his local friend Naota Kurahashi arrive on the island and encounter a kidnapping incident on their very first day. After intervening, he becomes a vampire and cannot leave the island, instead entering the island's nightlife where humans and vampires coexist.
Special Administrative Zone Administration Bureau
The Special Zone Management Office is commonly known as the Onmyo Bureau. Miu and Azusa held positions here; Human Azusa is responsible for supervising vampires and serves as the dormitory leader for Yuto and others. Masugata Hyoma from the disciplinary class is Miu and Azusa's superior. He works as a teacher at Tsukinaga Academy to monitor the situation, but does not actually teach. Moeka Awaji from the supervision team is responsible for the casino and other business rules.
Mayors and vampire representatives
The vampire Sayo Kojin serves as mayor, rarely appears publicly, and most external negotiations are handled by Anna Reticle. Sayo prioritizes the city's safety, even if it puts the vampires at a disadvantage; Anna values the vampire's perspective more, which leads to disagreements between the two.
Dormitories, coffee bars, and casinos
Rion Inazura handles dormitory chores and works with Hiyori Ofusa at the café Alexand, run by Moeka. Elina works as a dealer at a hotel casino; Nicola, who works at the same shop as her, also aims to become a dealer.
Routes and international PC versions
The official international guide lists Miu, Azusa, Rion, Elina, and the normal ending; The Nikolai route opens after clearing either route. The 2026 international PC version will feature 2560×1440 resolution, supporting switching between Chinese Simplified, Traditional Chinese, English, and Japanese, as well as cloud saving.
Theme songs and character songs
Yui Sakakibara performed the opening theme song "Scarlet," and Riryka performed the ending song "Kimi Dake no Boku." The four character songs correspond in order to Miwa Yarai, Azusa Furara, Rion Inasura, and Elina Olegovna Aven, with song merchandise and radio dramas listed in the release catalog.
A review of the making of the sheet music
In 2016, when Famishin explained the score, he listed "DRACU-RIOT!" as an example of personally organizing sheet music for performance. He first inputs note data through his DAW, then adjusts the sheet music, adding dynamics and playing techniques for the actual instrument.
Main Story: The Urban Crisis of the Miwa Line
Miu feels guilty for Yuto becoming a vampire, and Yuto accepts a new life, responding to her worries. When the city faces a crisis, Moeka gathers intelligence, Sayo prepares an evacuation cargo ship, and Erina senses the signal; Yuto and Miu hovered and detonated the incoming missiles.
Main story: Reveal of Azusa and Rion's storyline
Azusa's story reveals that Anna is Azusa's grandmother, who is of mixed heritage; Azusa, from the hunter clan, is ostracized by her clan for traveling with Yuto. The Rion route reveals Yuto and Rine's experiences in the orphanage and artificial experiments; After their final battle with Motoki, the two sucked each other's blood and returned to being human.
Main story: External pressure on the Erina and Nicola line
Elina once lived at the Russian Institute, and after Sayo destroyed the facility, she came to the sea city. In some storylines, Russia targets Yuto for military purposes, and both are pursued. The pressure on the Nicola route comes from the head of the family: the man tries to take him off the island, but after persuasion, he gives up.
The international version's three endings diverge
In the international official guide, Elina, Nikola, and the normal ending share a pre-selection chain: choose together with Miu, prefer large breasts, forget it, don't go with her, help her paint, or keep silent. Next, he promised to trouble Elina and respond to Elina's END; Apologies for the Normal END. If any character has already cleared the stage, after the same first six choices, change to 'Promise the Troublesome Rice Bush,' corresponding to Nikola's END.
