# Mark In very, very rare cases, in addition to their respective spots, koins may present a birthmark on their forehead with a pronounced kanji indicating the lineage they derive from. To be blessed with this mark, their parents must come from the same lineage. You should also know, the Genesis are also among the koin that can carry this mark. You’re going to need a lot of luck to find them! ![Tenkai](/files/4H30N4HUiapg8fZl0lxl) ![Lumine](/files/8UONZupEVfO8wQqDYjs5) ![Hatsu](/files/gbuKtXFS6zipjBMJ3fr8) ![Maneki](/files/iz4Sq5kWtpHNTbg4F6fv) ![Yume](/files/iuPlZ0H000ruddy6evsR) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
