I am not a native Chinese speaker so these will be machine translated. If there are more accurate translations, I would be happy to edit the description.
The kind-hearted Fluttershy (Softly) is timid and shy, but very good at communicating with animals, whether ants or dragons, all will be touched by her gentleness and sincerity. Despite her lack of self-confidence, when her friends are in crisis, she will stand up for herself and fight bravely.
