Byoukidere
A byoukidere (ビョウキデレ) is a character that is usually sweet and kind but suffers from a physical illness. The term comes from "byouki" (病気), which means illness, and "dere" (デレ), which means "lovey-dovey". Some byoukideres have tsundere personalities instead of being sweet and kind.
Due to their illness, many byoukideres are frail/feeble. They normally die from their illness, but if they don't die, they are chosen and saved by the protagonist.
