Light Screen

Biodata

Background / History

The Light Screen first manifested across the world and declared that humanity had forgotten its supernatural history. Its initial broadcast introduced a Holy Grail War and publicly identified Artoria as King Arthur, immediately triggering worldwide disbelief and scrutiny of everyone shown onscreen 2.

Su Yun secretly operates the broadcasts to collect Fantasy Power from the audience's shock, imagination, fear, and investment in the stories. The broadcasts also build faith in featured figures, enabling him to create or strengthen real-world superhumans connected to the footage 6 114 360.

The Light Screen's public image developed independently of Su Yun's secret role. Governments, researchers, corporations, and ordinary viewers treat each appearance as a global event, analyzing every scene for intelligence about erased supernatural history, Heroic Spirits, magi, Mysteries, and threats to humanity 15 114.

Later broadcasts expanded beyond the Fourth Holy Grail War into Yoriichi Tsugikuni's legend, Emiya Shirou's Holy Grail War, Chaldea's crises, Honkai history, the Land of Fairies, and other interconnected narratives 121 366 563 809 1247. By Chapter 1246, Su Yun begins relying on an AI-created version of the footage; his intuition indicates that its output reflects real events in the world's history rather than merely fabricated stories 1246.

Appearance

The Light Screen manifests in the sky on a global scale, functioning as an enormous visible display rather than a conventional device.

• It can appear simultaneously around the world, including at night, when its brightness makes the surrounding darkness appear like daylight 61.
• Broadcasts commonly begin with a black screen, text, and a ten-minute countdown that allows viewers and institutions to prepare 61 809.
• It may remain in the sky after a program appears to have ended, then begin an unexpected bonus or side-story broadcast 1054.
• Its camera work can deliberately conceal information, such as obscuring a person's face or showing only part of a figure 61 114.

Capabilities

Worldwide Projection

The Light Screen can display footage to a global audience regardless of distance or local conditions.

• Its arrival causes people worldwide to stop work, school, and other activities to watch 41 405.
• Governments organize experts, recording equipment, and emergency analysis teams whenever it appears 15 41.
• Its schedule is irregular; broadcasts may be separated by days, weeks, or longer intervals after an arc concludes 41 563 809.

Narrative Presentation

The Screen presents footage as a structured audiovisual program, using camera shifts, subtitles, narration, music, titles, and countdowns to frame events for viewers.

• Narration explains unfamiliar concepts such as Noble Phantasms and magecraft, allowing the public to follow supernatural events 16 19.
• It can shift between battles, historical scenes, memories, dream sequences, and epilogues without warning 17 522 1054.
• Its contents are widely believed to reveal erased events from the past; Gilles de Rais explicitly describes it as a screen that records and broadcasts past events 203.
• Some broadcasts contain deliberate omissions or compressed developments, leaving viewers and even real-world counterparts uncertain about what was excluded 1306.

Audience Influence and Power Generation

Viewing the Light Screen produces Fantasy Power and faith power for Su Yun, making the audience's emotional response a strategic resource.

• Combat, mystery, admiration, fear, and speculation generate Fantasy Power 17 117 257.
• A single extended Holy Grail War broadcast generated more than fifty thousand Fantasy Power, though audience fatigue sharply reduced returns later in the program 114.
• Faith built through broadcasts supports the awakening and enhancement of individuals who correspond to onscreen characters 311 360.
• Su Yun spaces broadcasts partly to let audiences recover their capacity to generate Fantasy Power 114.

Reality-Adjacent Effects

Although most footage is presented as a broadcast, its content can affect the real world beyond ordinary viewing.

• Lancer's charm ability briefly influenced real-world viewers before the footage appeared to block its effect 16.
• Su Yun embeds subtle psychological suggestion into certain broadcasts to heighten viewers' sensory and emotional reactions 394.
• The Destiny Observer can retrieve background information on entities that have appeared in the footage, though unrevealed or locked information remains inaccessible 78.
