Shuka is generally approachable and friendly but can exhibit a deadly and ruthless side when the situation demands it.

Her relationship with Rein also evolved positively, with Shuka seeking her advice on how to keep Kaname’s affection focused solely on her, showcasing her growing respect and camaraderie.
