Hotaru Akai belongs to the Kindred of the East.
She's an undead she-demon, who follows the dharma of the Thrashing Dragon, which means she seeks all the pleasures life can offer.
The sign on her earring means "Dragon", on her necklace "Moon", on her hairpin "Sun" and on the last piece of jewellery "Akai Hotaru" (Red Firefly).
The inscription in japanese says: "Thrashing Dragon".
