Eren Long

Eren Long is a silver-haired Nest veteran whose partnership with the Silver Dragon defines both his power and his grief when the Curses are released.

Biography

Arx, the Sacred Desert, and Bloodline Revelations

Eren confronts Bloodhound as a scarred veteran who previously killed two enemies while protecting a Cursed Child. He helps evaluate Michael's Fang bloodline, supplies a Diamond Transportation Token for Michael's first mission, and works within the Nest's uneasy effort to protect Curse Users from the Supreme Human Alliance. His pride rests less on avoiding injury than on ensuring the child under his protection survived. (Chapters 742–750)

The Unknown Domain and the New Era

After Michael frees the Curses, Eren's Silver Dragon chooses to leave while Evee's Rainbow Dragon stays, making him feel abandoned and useless. Evee forces him to acknowledge that the separation cannot be reversed. Eren then accepts a Human Protection Service post in the Zelgon Stellar System, redirecting his experience toward guarding Lesser Humans and confronting an Insectoid threat rather than pursuing his former partner. (Chapters 1094–1095)

Appearance and personality

Eren is explicitly silver-haired and bears a scar associated with his earlier fight against Bloodhound's group; other physical details are not fixed. He is proud, protective, sardonic, and deeply attached to his Curse. Losing that lifelong companion exposes vulnerability beneath the veteran confidence, but he ultimately accepts a constructive duty instead of remaining immobilized by grief. (Chapters 742, 1094)

Silver Dragon Curse and Nest expertise

Eren's long-term partner is the Silver Dragon Curse, which grants him the power expected of an experienced Nest Curse User. The corpus does not fully catalogue its attacks in the cited record, and the later separation removes his Curse access. His enduring capabilities are experience, knowledge of Cursed Children, mission planning, and the judgment to protect vulnerable populations as a former Curse User. (Chapters 742–750, 1094–1095)

Relationships

Evee is Eren's daughter and the person who helps him accept the Silver Dragon's departure. The Silver Dragon is described as friend and lifelong partner rather than property. Michael Fang receives Eren's mission support and later funds the protection program that gives Eren a new purpose. (Chapters 742–750, 1094–1095)

Items

Eren gives Michael a consumable Diamond Transportation Token that carries him to the Sacred Desert without creating an unwanted Link of Loyalty. The token breaks upon use and has no generated item page. (Chapter 750)
