Tag: Imouto-type Heroine
These games have at least one imouto-type-heroine. An imouto-type heroine is a heroine who is not a sibling or a step-sibling to the protagonist but acts and gets treated like a little sister anyway.
This tag is used as a character trait of heroines. For actual sister connection please use the sister heroine tag.
TL Note: Imouto means younger sister.
