Even the carpenter guy, who was supposed to be a production type ability user, was better than her.
A plant tamer was indeed powerful when there were many plants around, but they would also be helpless in front of many beasts and monsters.
Not to say that there were many mutant plants out there that couldn't be tamed at all and were not friendly toward tamers like her.
It was only because of her taming ability that plants 'liked' her.
Compared to non-human beings loved by nature, she was like a fake who forced plants to obey her and like her through coercion and persuasion.
After knowing that the plant-tamer girl could not be another water lily, everyone fell into another round of despair.
They could not possibly come out of the boat during the siege and to be honest, most of the people in this boat didn't have any abilities that could safely take away the flower of the water lily without offending the water lily.
