# Libra of the Vampire Princess Summer DB entity ID: 86b8a71d\-e1a3\-4c6b\-9cb6\-a95d370ce828 Steam App ID: 604170 A Story of Battle, Blood, and Love\! Shuma Kusanagi is just an ordinary boy\.\.\. Until one day, he's suddenly abducted by the vampire ringleader Iris Pumila, who reveals a shocking secret: Shuma has vampire blood coursing through his veins, and it is her destiny to awaken him\! Although Shuma manages to return to his normal life, he now faces unexpected challenges\. His body is overwhelmed by sudden vampiric impulses, making it harder to maintain his humanity\. To make matters worse, strange individuals begin appearing, disrupting his once\-peaceful existence\. First, there's Mari, a werewolf maid who was tasked by Shuma's deceased father to restore the Kusanagi family to its former glory\. Then comes Calen of the Officinalis family—one of the three progenitor vampire lineages—who boldly declares herself his fiancée\. On the opposite side is Aoi Kamishiro, a vampire hunter sent by the Holy See's secret anti\-supernatural organization, the Rubina\. And lurking in the shadows is Lycoris, an assassin dispatched by Iris, seemingly mocking Shuma's hopes for a normal life\. Caught between these conflicting forces, Shuma struggles to live as a human, not as a vampire\. However, the rising tide of darkness threatens everything, forcing him to wield the very powers he despises\. In the end, Shuma must overcome his inner turmoil and embrace his supernatural heritage—if only to protect those he cares about from the evil closing in around him\. Main Features 30\-40 hours of gameplay\. 4 paths: Calen, Aoi, Mari, and Lycoris\. 2D battle scenes\. ## Game information - Type: game - Developer: onomatope\*, MiKandi Japan - Publisher: onomatope\*, MiKandi Japan - Release date: Jun 20, 2017 - Coming soon: false - Free to play: false - Parent Steam app: Not collected - Genres: Adventure, Casual, Simulation - Categories: Single\-player, Steam Achievements, Steam Trading Cards, Family Sharing - Platforms: windows - Website: Not collected - Screenshots: https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/604170/ss\_d44f916af149061529ddbadb3a09efcaf38a0ff7\.1920x1080\.jpg?t=1730443952, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/604170/ss\_2061c16e76fa94cb556f0b94d413e7a7f3611924\.1920x1080\.jpg?t=1730443952, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/604170/ss\_fbc49d37632c4aac0bdfe880f63ed4b2578a76dd\.1920x1080\.jpg?t=1730443952, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/604170/ss\_5951fc490d804fdf6f6c68c2efb0af5478455a50\.1920x1080\.jpg?t=1730443952, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/604170/ss\_0a571b137bb7375a24b6e25b3b0029aec34954ef\.1920x1080\.jpg?t=1730443952, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/604170/ss\_0a6cbb906516e6f925e38d292e6f460746b91c74\.1920x1080\.jpg?t=1730443952, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/604170/ss\_3aebe5a342c140c24e2f9f750ef4f6452740f7b9\.1920x1080\.jpg?t=1730443952, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/604170/ss\_6ff203f1679e5b426d6a4cab3a75b1aa5801b321\.1920x1080\.jpg?t=1730443952, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/604170/ss\_248d621641b34f0c0b9d77330e6c401d9631ffdc\.1920x1080\.jpg?t=1730443952, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/604170/ss\_77bb290d7603575871d2dda84d6bea2422c75a76\.1920x1080\.jpg?t=1730443952, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/604170/ss\_bacf10000260bc3216d01a57c2881f8191d98630\.1920x1080\.jpg?t=1730443952, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/604170/ss\_3a12226fdbe2742c0b34a0a893c595d2faad99d0\.1920x1080\.jpg?t=1730443952, https://shared\.akamai\.steamstatic\.com/store\_item\_assets/steam/apps/604170/ss\_8c210fbb6395623b3d68844a94a05262e990ea5d\.1920x1080\.jpg?t=1730443952 - Price: 3999 minor units USD; discount 0% - Price country: US ## Observed metrics - Current players: 0 - Steam review count: 43 - Steam positive reviews: 37 - Steam negative reviews: 6 - Steam positive percentage: 86.04651162790698% - Summer DB rating: No native votes Review filters: \{"language":"all","review\_type":"all","purchase\_type":"all","filter\_offtopic\_activity":0\} ## Player history [Seven-day chart data as Markdown](/api/v1/entities/86b8a71d-e1a3-4c6b-9cb6-a95d370ce828/player-metrics?days=7&format=markdown) · [JSON](/api/v1/entities/86b8a71d-e1a3-4c6b-9cb6-a95d370ce828/player-metrics?days=7) Chart values are hourly observed maxima.
