It was Christmas Eve at the ADA headquarters and the members were celebrating with their annual Christmas party. Kunikida and Fukuzawa sat together by the fireplace, sipping hot coco and discussing their plans for the new year. Nearby, Tanizaki and Naomi were decorating the large Christmas tree, hanging ornaments and stringing popcorn garlands.

In the kitchen, Yosano looked out the window at the falling snow. She enjoyed a glass of wine as she watched the white flakes gently drift to the ground, lost in thought. Meanwhile, Atsushi, Ranpo, Haruno and Kyoka sat together on the couch, laughing and chatting happily as they drank cups of cocoa topped with marshmallows.

Out on the balcony, Dazai stood alone looking up at the starry sky. The festive music and cheerful voices drifting out from inside did little to lift his melancholy mood. In his hand was a small gift wrapped in shining red paper - a present he had meant to give to Chuuya. But with his former partner now living across the city as a member of the Port Mafia, Dazai knew this Christmas would be lonely without him.
