Rei

Rei is one of the 3 monsters summoned by Keima to assist the inn. She has silver hair and crimson eyes like glittering rubies. Rei has great pride as a dungeon monster, and as a Vampire. After her summoning, she wanted to crush every single "invader" of the dungeon, just to prove her loyalty to her Lord, Keima. However, at first, her job was being a simple receptionist. She was devastated. She just wanted to be useful to her Master. She is quite intelligent as she could deduce who was knocking on her door in seconds. Neruneh, Rei, and Kinue were summoned with Dungeon Points after Kei...
