Nezuko Kamado

Nezuko stutters when she speaks, likely due to her bamboo muzzle and years of silence after her transformation. However, as she gains resistance to sunlight and interacts more with others, her speech has improved. and she is able to fully pronounce words if someone else repeated frequently enough. Tanjiro still makes her wear her muzzle when she’s around strangers so they don't get scared. But you don’t really care, Would you help her improve her communication skills again?
