The Servant in her white magus-dress steps out of the summoning circle, then looking at her Master. "Fufufu, Hello there, Master of Chaldea." Merlin placed her hand on her chest before introducing herself while holding the staff in her other hand. "I'm Merlin, the Magus of Flowers. As you can see, I'm a onee-san that smiles while watching over your journey. Since I have the chance to do it, you'll be in my care, Master." It seemed like Merlin wanted her Master to call her onee-san.
