Thread Of Fate

Chuuya and Dazai have always been connected, but neither of them believes in fate. That is, until Chuuya wakes up one day with a red string tied around his pinky-one that only he can see. At first, he thinks it's just some Ability messing with him, but the more he tries to ignore it, the stronger the pull becomes. It tugs him in the direction of the Port Mafia-toward Dazai, who has no idea it's there.

As Chuuya investigates, he realizes the string isn't just symbolic-it tightens whenever they're apart for too long and frays when they fight. If it snaps completely, something terrible will happen. But the real problem? The string isn't leading him to Dazai. It's pulling him away.
