Samayou Midara na Lunatics

Sharing a bond that goes well beyond what royalty — or anyone, really — is supposed to have, Princess Eifa and her brother Prince Alois make up the kind of pair that looks perfect on the surface until you realize the feelings involved are deeply forbidden. She's known as the 'daughter of the Moon,' he's the 'son of the Sun,' and together they're the kind of pair that looks perfect on the surface until you realize the feelings involved are deeply forbidden. When their stepmother hands Eifa a love potion and things spiral from there, a jealous witch catches wind of the situation and curses them both — leaving Eifa as herself only at night, while Alois takes over their shared body during the day. Then the kingdom finds out about their relationship and banishes them entirely. Now they're on the run, cursed, and searching for another witch named Yorandel who might be able to undo what's been done. This 2-episode OVA from Studio 9 Maiami leans hard into the dark, atmospheric side of its medieval fantasy setting. The supernatural curse mechanic gives the story more structure than you'd expect from the genre, and the production quality is noticeably solid — detailed character designs and a moody soundtrack that actually fits the world. If you've watched something like Bible Black and appreciated when these titles put genuine effort into world-building, this scratches a similar itch. Fans of Discipline: The Record of a Crusade who like a darker emotional undercurrent will find familiar ground here. It's not trying to be subtle about what it is, but it does commit to its premise more than most.
