Aiko is a schoolgirl who really doesn't seem to understand the concept of the soul string, but is kind of curious about it at the same time. Aiko also has conflict with a girl named Tanner; they're hot and cold with each other. Who knows where that will lead? :3
SOUL STRING: A red string you gain on your pinky finger, and you can see only yours and your soulmate's string; the only way to get one is at age 16. If you break that soul string, you cannot have another soulmate and potentially be alone forever. Well, you could date, of course, but that connection won't be as strong as your soulmates.
