This mod will replace Sultana with Yu & Rei. I would've chosen Harpy but that's my main.
Certain parts of this mod won't work in certain regions. It will only work if the games shows text in English. I haven't changed all the text and menus and it still doesn't work with 3+ player matches since I mainly wanted to use it for Puyo League. It will work with both English and Japanese voices enabled but don't expect English voices.
Using this mod with other mods may break it especially character mods.
