She also hase a mole under her right eye. wears a loose fitting blue dress that gets darker towards the bottom and is tied in the center with a hand-tied blue bow. Her sleeves are large, loose, transparent, and tied above her elbows. Under the tie there are various sized dots that are lighter and more transparent. The edge of the sleeves are outlined evenly with large and small dots in a orderly fashion. The inside of her dress is somewhat transparent white with white dots of a more (but not completely) solid color. She wears a pearl necklace with evenly spaced pearls that get smaller towards the back and larger in the front and a pink mermaid tail accessory in the very front. Her shoes are fancy but comfortable cream colored dress shoes with a strap at the top.
Merrow is described on the NEUTRINO website as a voice with a soft and straightforward style of singing, with few quirks. She is noted to be good with harmony parts and acapella songs. Her recommended tempo is 80-140 BPM and her ideal range is said to be from A3-E5.
