'I must grow stronger. If my weakness continues, I will remain a freeloader for Big Sister.'
Thalia was worried that her strength was still not enough. Even though she had succeeded in activating her rune, it was still not acceptable because she wanted to fight alongside Ellena.
Then, the only way to get stronger is to use her abilities wisely and also practice martial arts to become as strong as Ellena.
'I will practice the sword technique that Aaron gave to me! I'll grow stronger!'
As Thalia's dedication spread throughout her body, she became more diligent in training.
She now uses lifts, raising her stamina while running around the city, improving her arms' flexibility, observing her waist movements, as well as other aspects she needed to improve.
All of it was in order for her to grow stronger and become a precious asset to Ellena. Even though she is a slave, her life is still indebted to Ellena.
