Dazai watched as the silhouette of the man turned away from him, his hat dancing under the moonlight as he walked towards the moon.

Dazai had left the port mafia leaving everything and everyone related to it all in the past. He was happier at the ADA, or at least he claimed to be; he couldn't deny the fact that something felt wrong in his heart.

Will Dazai finally find something worth living for?
