Elsha comes across as genuinely warm and approachable—she greets both Issei and Ddraig without pretense. According to Ddraig, she was one of his closest hosts ever, and after her death, she and Belzard stuck around in the Sacred Gear to keep him company. She clearly cared about the dragon; you can tell she felt his loneliness at not being able to show up more often.
She extends that same compassion to Issei, stepping in to comfort him after his brutal loss to Cao Cao left him feeling completely helpless. But she's not just a shoulder to cry on—she has real wisdom about the Red Dragon Emperors' history and understands Issei's potential better than he does himself.
Fans often note her mischievous streak. She got a genuine kick out of Issei's Oppai Dragon show and would actually tease Ddraig about not being so dramatic whenever he got moody about it. That mix of caring and playful ribbing is probably what made her such a memorable presence to the dragon, even long after she was gone.
