Misaka
Misaka (美坂) is a SHIORI created by ls. It is a SHIORI that is straightforward to write simple ghosts in, and also has a setup for creating ghosts with different modes very easily.
Information about Misaka and its syntax can be found on its specification pages and FAQ.
Misaka reads files as Shift_JIS and has no way to change this setting, so it may be difficult to write ghosts with it in languages other than Japanese or English.
