Edin Dan is a D-rank Regular Scout renowned for his exceptional speed, first noted even during his E-rank days. He possesses long black hair, usually tied in a ponytail, and favors an orange vest over brown shirts. To evade FUG surveillance during the Workshop Battle on the 30th Floor, he adopted the alias "Dinn," dyed his hair orange, and wore an orange tank top with black training pants. Personally proud of his abilities, Dan harbors a deep reluctance to form new teams stemming from past trauma. He was the sole survivor after his original teammates were killed, leading him to abandon climbing the Tower and become a hunter on the 25th Floor. This resolve caused him to decline all climbing invitations until Khun Aguero Agnis forcibly recruited him through a rigged gamble. Joining Khun's team, Dan participated in internal ranking battles but was placed last after a swift defeat by Novick. His background involves significant betrayal and violence. Initially resisting Khun's recruitment due to disillusionment with the Tower's lethality, Dan became part of Team Tangsooyook after losing the gamble. His role evolved into supporting Khun's strategies, including acting as a "fence" around Rachel. During the Workshop Battle prologue on the 29th Floor, he utilized an AI program named Emile to locate enemies and disable cannons, securing a team victory despite Khun criticizing the risk. A pivotal moment occurred when Rachel intervened to save him from FUG operatives Apple and Michael, then asked him to "become her legs." Dan recoiled at this request, citing her betrayal of friends, which provoked Rachel to stab him repeatedly, causing permanent leg damage. Despite this injury, he insisted on participating in the Workshop Battle to demonstrate resilience, refusing to "give in to despair a second time." Though initially unable to run at full capacity, he gradually regained limited mobility, employing his speed in short bursts during later missions. In the Workshop Battle, Dan partnered with Rak Wraithraiser (disguised as "Red Hawk") to win the 15th round of the "Plug Battle" event. His tactical contributions continued into the Hell Train arc, where he scouted adversaries like Aka Williams and used his speed to navigate maze challenges by pressing buttons to open doors. He later assisted in missions such as capturing Beniamino Cassano and navigating the Name Hunt Station, subduing unnamed Regulars and surviving a sedative attack thanks to allies Leesoo and Hatsu. Dan's core ability is extreme speed as a "Speeder," generating red or yellow electric-like sparks at his feet. This mobility was severely impaired after Rachel's attack, but partial recovery allowed tactical applications in combat and reconnaissance. Ran, a prominent Khun team member, acknowledged Dan's unmatched velocity despite its limitations in direct combat.
