Bebe is a magical beast, a shadowmouse and the companion of Linley Baruch.
When Linley was searching for treasure in the ancestral hall of the Baruch clan, he discovered a 20-centimeter long black mouse chewing on a piece of stone rubble, an infant black Shadowmouse. Because of the admiration he felt for the magus who tamed the Seventh-rank Velocidragon magical beast, Linley wanted a magical beast of his own.
Delia/Doehring Cowart suggested that Linley try to form a bond of equals with the Shadowmouse. So Linley, over the course of a year, convinced the Shadowmouse into trusting him. Starting with feeding him raw Hare, Linley eventually fed the Shadowmouse cooked meat. As they both grew, Bebe seemed to grow attached to Linley. When Linley was on the road to the Ernst Institute, Bebe instantly chased after him. Knowing that he was not going to see Linley for a long time, Bebe formed a bond of equals so he could travel with Linley.
Bebe accompanies Linley throughout all sorts of events, always staying by Linley's side. After they both enter the Mountain Range of Magical Beasts, Bebe helped in taming Haeru who afterward joined the inseparable duo.
