The opposite of the symbol of the seven deadly sins, the Hope Family created seven individuals that symbolised the seven heavenly virtues.
Bunbun's mother or Claire manifests the heavenly virtue "kindness" her ability to heal has improved drastically, even Leafinia cannot deny that she is at her level or probably even greater in terms of healing capabilities.
But just like the individuals that manifest and symbolise seven deadly sins, they carry some burdens because of their power.
The one that carries the virtue "kindness" cannot harm any being, even if they are their enemy, harming life is impossible for them and they have become something like a plant, they only need to absorb energy from the source of life, the sun and the origin of life on land, water.
That is okay for Claire, she knows that her family will protect her and the soldiers will do everything just to keep her safe, they will not hesitate to lay down their life for her.
