Stories
3Case File I
Sana is a military doctor in the Bifrost Military. Born in the border region, she grew up in the Stoker Complex and loved taking care of the children around her from a young age. Later, worried about her friend who had joined the army, Sana applied and passed the assessment to enter the military academy, eventually becoming a military doctor. Relentless and dedicated, Sana refuses to give up any chance to save a life even in the most dangerous situations on the battlefield, earning deep respect from the soldiers in her unit.
Case File II
Sana's friend, Masa, was someone who naively believed that war was a progressive path to a better future, enlisting with the hope of making the world a better place. Fearing that Masa would be crushed after witnessing the real battlefield, Sana applied for the military academy right after Masa enlisted and became a military doctor. Sana's worries proved justified. Once Masa arrived at the front lines, she was indeed unable to adapt. Just then, Sana arrived at her side as both a military doctor and a comrade, giving Masa the strength to persevere. However, having been raised in the Complex, Masa was simply not built for the battlefield. After suffering a severe injury and being saved by Sana, the two had a long talk. In the end, Masa chose to discharge, while Sana stayed in the military.
Case File III
Unlike Masa, Sana, hailing from the border regions, never harbored any illusions about war. She was far better adapted to its cruelty than Masa. Yet, Masa's passion for life deeply influenced Sana, making her unwilling to abandon any chance to save a life, even under the most perilous circumstances. Through her own studies and the trial of war, Sana gradually grew into a top-tier military doctor, developing her unique insights into complex afflictions related to Echo Crystals. It was precisely because of Sana's exceptional skills that the Underworld Reaper sought her out, hoping she could treat the children suffering from Echo Crystal Corrosion in the Dark Road. Sana saw no reason to refuse.

Pneuma FieldT1Limit-broken Cases enter a dangerous Pneuma state when they overuse their power. While in this state, they automatically activate a Pneuma Field. When a Case not in the Pneuma state fights within an active Pneuma Field, their passive and status effects have a 2% chance to fail. The failure rate will increase with the star level of the Case in the Pneuma state, up to a maximum of 5%. This rate stacks when multiple Pneuma-state Cases are deployed.
