Nel

Nel is one of Riser Phenex's Pawns. She's the twin sister of Ile. Despite their innocent appearance, Ile and Nel are very dangerous and will cut down their opponents without a second thought. However the twins have demonstrated a habit of underestimating their opponents which in their fight with Issei resulted in their humiliating defeat. Ile and Nel first appeared in Volume 2 at the Occult Research Club, when Riser is introduces his peerage to Rias after the two of them decide to have a Rating Game. During the Rating Game, they fought against Issei in the replicated gymnasium.
