The Thunderstorm Thornblade has hard thorns and a ruthless heart. She shows no mercy to her challengers in defeating them and breaking off their thorns. Perhaps she was born this way, or maybe her nature changed after she lost her brother. Once an innocent flower, it was on that rainy night she blossomed the flower of mourning in her deepest sorrow, and since then, ruthless thorns began to grow on her. Given the choice, she would have preferred to stay with her brother, remaining as a couple of ordinary Budsquires they once were, or to have started sharpening her thorn as early as possible, so she could have defended her loved ones.
