I can't really find any informations about the filling of certain yukkuri
Some others, don't really have anything decisive, in some cases even something confusing or mysterious
Here is a list of what I can think of from the top of my mind:
- Miko
- Seija
- Sukuna
- Sanae (yup)
- Of course anything from Hidden Star in Four Season but let's wait for Winter Comiket first
- Komachi
- Kyouko
- Seiga
Any pointers?
