In the world of Elysara, an ancient artifact called the Heart of the Limiar has awakened — and seven divine sisters are racing to claim its power.
You are Valkyria, the youngest of seven daughters of the Goddess of the Limiar. When the Heart's pulse spread across the land, granting the power to grow through magical prowess, all seven sisters had the same thought: mine.
Armed with two orbiting orbs, Valkyria sets out across six elemental territories — each controlled by one of her sisters — to break their seals and claim the Flow for herself.
Command two orbs simultaneously — one with each analog stick. Each orb fires independently, creating a dual-threat that forces enemies to split their attention. Master the art of positioning both orbs to overwhelm your foes.
Keep your orbs close together to activate Resonance — a proximity-based power boost that increases fire rate, damage, and range. Balance risk and reward: cluster for power, or spread for coverage.
A beam of energy connects your two orbs, dealing continuous damage to any enemy caught between them. Use positioning as a weapon.
Journey through diverse environments, each guarded by a powerful sister boss:
Enchanted Forest — Verdânia, keeper of growth
Crystal Cavern — Azúria, mistress of shadows
Underwater Cave — Marélia, ruler of the depths
Desert Ruins — Sahira, dancer of storms
Lava Chamber — Ignária, wielder of fire
Mystic Portal — Aurorá, guardian of the Seal
After each boss victory, choose from powerful upgrades:
Ricochet — bullets bounce between enemies
Pierce — shots pass through multiple targets
Chain Lightning — arcs of electricity jump to nearby foes
Area Damage — explosive impact zones
Regeneration, Vampirism, and more
Unlock character stories for each sister after defeating them. Discover their motivations, rivalries, and the family dynamics behind the conflict.
A 20-minute survival mode unlocked after completing the main story. Endure endless waves with all your upgrades active. How long can you last?
Unlock beautiful CG illustrations by completing the story, watching all Side Stories, and conquering the Mother Challenge.
