Bestiary Entry 159:

Shizuka's Bestiary:

"This is a Youkai that takes on the appearance of a giant shark! Genbu-san mentioned that they feast on the deceased. Which reminds me, in her current form Genbu probably looked quite appetizing to them. It seems the Dark Fin lay a lot of eggs, so are the younger sharks properly taken care of? The presence of its huge shape is terrifying, but it melts like a shadow."
