Ep. 15: Silver Crow loses his wings to Dusk Taker and seeks Sky Raker's guidance.

15

During a duel, Silver Crow discovers Dusk Taker levels up by threatening other Burst Linkers rather than fighting. Although Silver Crow initially dominates, Dusk Taker uses Demonic Command to permanently steal his Aviation ability once his SP gauge fills. Defeated and stripped of his powers, Silver Crow loses Burst Points and leaves the Accelerated World. Dusk Taker, known as Seiji, refuses to return the ability until graduation and forces Haruyuki and Chiyuri to keep the incident secret from Takumu and Kuroyukihime. This secrecy strains Haruyuki’s friendship with Takumu, leading to depression and thoughts of uninstalling Brain Burst. Unable to fight without wings, Silver Crow loses a match against Ash Roller. Feeling pity, Ash Roller takes him to the old Tokyo Tower in the Unlimited Field to meet Sky Raker, his predecessor in aerial combat.
