Background / History

Keir first became acquainted with Yicha through an academic disagreement over Yicha's work, Six Applications of Power Domain Theory in Will-Based Spells. Their dispute became a friendship, and they subsequently arranged secret cross-planar academic discussions. 1

When the War of Dawn summons all angels to mobilize, Keir deserts rather than participate in fighting and killing. Hearing that Yicha is in trouble, he travels to find him and asks to remain at his side. 5

Keir accompanies Yicha's group to Chaos Hell despite never having visited it during the seven-thousand-year Isolated Island Era. Chaos Hell's environment overwhelms him: he vomits order energy and becomes too weak to travel independently, prompting Yicha to have Xiqisi take him to the Demon Courtyard. 6 8

At the Demon Courtyard, the Fallen Angel Cult mistakes Keir for the angel sent to save them. His accidental miracles reinforce their belief. Though he initially tells them that Lucifer does not exist and that he cannot take them away, sympathy for their despair leads him to claim that the first fallen angel will come for them and to name Yicha as that figure. 11 12

The cult's faith later changes Keir into the likeness of the First Fallen Angel and grants him a portion of that being's power. He develops and explains a Transfiguration theory based on changing an existence's origin, destination, and path. 20

Keir guides Yicha's attempted Transfiguration into an order-domain existence. He refashions Yicha's horn chain into an anchor and uses his own order energy to generate an order field in the Law Field Energy Chamber, but Yifomiet's attack severely wounds him and interrupts the process. 21 22

After Nese teleports him away, Keir's injury worsens in Chaos Hell. His unstable miracles repeatedly create dangerous outcomes while he and Nese attempt to survive the Fire-Thunder Zesan River and Alexander Hanging Ghost's forest. Goodbye ultimately consumes Keir's physical form to contain his remaining energy safely; Yicha concludes that his pure order energy cannot inhabit a demon shell. 31 32 35 36 37

Appearance

Keir is a winged angel with glittering golden eyes, usually associated with white robes, white feathers, and visible holy radiance. 5 11 20

• His wings and order-energy aura distinguish him as an angel. 8 31
• His holy radiance vanishes when he transforms after speaking prohibited profanity. 5
• Faith from the Fallen Angel Cult changes him into the appearance of the First Fallen Angel. 20
• His right shoulder and wing are severely damaged by Yifomiet's spear. 22 31

Personality

Keir is sincerely compassionate, even when that compassion leads him into trouble. Faced with the Fallen Angel Cult's centuries of waiting, he cannot bring himself to leave them hopeless and instead makes a promise he is not certain can be fulfilled. 12

He is intellectually curious and competitive, particularly in discussions with Yicha. He eagerly seeks unpublished principles, analyzes Yicha's horn chain, and develops Transfiguration Theory with unusual seriousness and clarity. 7 20

Despite his scholarly ability, Keir is anxious and easily flustered in danger. He avoids combat, struggles to adapt to Chaos Hell, and panics when using miracles under pressure. 5 8 31 32 His politeness remains remarkably consistent, including when speaking with the hostile Alexander Hanging Ghost. 33 34

Abilities & Skills

Order Energy

Keir is an order-domain energy being. His order energy can be directed through spell formations and used to create a temporary order field. 22 31

• Generates the order environment needed for Yicha's attempted Transfiguration. 22
• His energy can be concealed by Yicha's golden horn chain. 7 8
• Pure order energy is incompatible with ordinary demon shells. 36
• Chaos Hell weakens him severely and attracts surrounding disorder energy to his damaged form. 8 33

Miracle

Keir's innate angelic ability is Miracle, a direct but highly unstable application of order energy. 31 32

• Can produce physical phenomena without visible preparation, including light-feathers that become flowers. 11
• A miracle enables Yicha's escape from Beelzebub's captivity. 40
• Its results vary with Keir's mood, circumstances, desired outcome, and even incidental thoughts. 31 32
• His panicked miracles can worsen a situation, such as turning him into a heavy sphere that plugs the Fire-Thunder Zesan River. 32

Transfiguration Theory

Keir's Transfiguration model defines an existence through origin, destination, and path. A complete Transfiguration requires all three to be replaced in a coherent whole. 20

• Identifies faith power as a means to alter a being's path. 20
• Reforges Yicha's horn chain into a new anchor representing the origin position. 21
• Requires genuine acceptance of the intended final position rather than a merely verbal agreement. 21
• Requires the transformation to occur within the energy conditions of the target domain. 22

Academic Knowledge

Keir is a capable theoretical researcher with knowledge of faith, energy analysis, angelic history, and spell theory. 1 12 20

• Originally met Yicha through an academic dispute and continued exchanging research with him. 1
• Recognizes the Fallen Angel Cult's doctrine as a collective delusion while warning that their will can still produce faith power. 12
• Extracts information about the Isolated Island Era and the Chaos Child from Alexander Hanging Ghost through careful conversation. 34

Angelic Prohibition

Keir is subject to a built-in angelic code of conduct that reacts to profanity by transforming him into animals. 5

• Becomes a winged pig after an impure statement. 5
• Later transforms into a fat rabbit after swearing. 5
• Attempts to substitute “turnip” for prohibited language. 20

Relationships

• Yicha / Ichaint — Academic rival, loyal reader, best friend, and traveling companion. Keir deserts the War of Dawn summons to seek refuge with him and later helps carry out his Transfiguration. 1 5 21 22
• Nese / Villed — Fellow companion. Nese attempts to heal and protect Keir after his injury, while Keir helps him navigate Alexander Hanging Ghost's forest. 31 33 34
• Xiqisi — Fellow traveler who carries Keir to the Demon Courtyard, then leaves him with the Fallen Angel Cult. 8 10 11
• Sankarabi — Leader of the Fallen Angel Cult and one of Keir's believers. Keir's words about the First Fallen Angel profoundly shape Sankarabi and the cult's hopes. 11 12
• Fallen Angel Cult — Their collective faith causes Keir to take on the appearance and part of the power of the First Fallen Angel. 20
• Goodbye — Yicha's hellhound consumes Keir's physical form to preserve his energy after his injuries become critical. 35 36

Story Role / Major Arcs

Desertion and Journey to Chaos Hell

Keir abandons the angelic war summons and joins Yicha, Nese, and Xiqisi. His arrival confirms Yicha's information about the War of Dawn, while his inability to withstand Chaos Hell becomes an immediate liability for the group. 5 6 8

Fallen Angel Cult

Mistaken for a savior by the Fallen Angel Cult, Keir accidentally becomes central to their faith. His attempt to comfort them establishes Yicha as their promised First Fallen Angel. 11 12

First Fallen Angel and Transfiguration

The cult's faith transforms Keir and enables him to formulate a practical Transfiguration method. He becomes Yicha's guide during the attempt to escape Beelzebub's demonic suppression through an order-based existence. 20 21 22

Survival in Chaos Hell

After Yifomiet's attack, Keir and Nese are stranded in Chaos Hell. Keir's unstable miracles, his worsening destruction-energy wound, and his unexpected rapport with Alexander Hanging Ghost define their escape attempt. 31 32 33 34 35
