Character in Fire Emblem: Three Houses and member of the Golden Deer.
Lysithea is a hardworking girl with a no-nonsense attitude who has a desire to improve her abilities. Being the youngest student at 15-years-old, she dislikes being treated like a child and can be impatient with those who annoy her. Despite wanting to look independent and mature, she has an intense fear of ghosts and is an avid lover of sweets, especially cake.
The reason for her impatience is because of her shortened lifespan, caused by being implanted a second Crest onto her when experimented on by Those Who Slither in The Dark.
