Chiara finds herself transparent and with a red string attached to her little finger. With nothing else to do she decides to follow it, only to find Keita with the other end of the same string attached to his other little finger. He already feels enough eyes on him, he doesn't need a ghost following him wherever he goes and trying to convince him to spill his deepest secret to everyone. But now that she got close enough to him it doesn’t seem like she can go away even if she wanted to.
Just a gremlin that came from the depths of Tartarus to bring you all of the lore.
