ギルベルト・フォン・リィンベルク

The main hero.

He seems to have been bedridden for a while, and often gets scolded for leaving his bed. He's generally kind and refined, but also has a slightly mischievous side. He's objective about his own appearance, deliberately acting "like a prince" to annoy the protagonist.

He always wears an elegant smile, but he'll sometimes wear a slightly melancholic expression.

He seems to like the protagonist quite a bit, since she doesn't seem to be the type to stick close by, so he often takes care of her.

Interestingly, he also has a hobby of making picture books.
