This one was actually the first one I ever wrote.
Like Scrabble
It was a well known fact in the underground that Dr. Jackal treated every assignment as a game, basing its worth solely on its entertainment value. It was not, however, a well known fact that this applied to his personal life as well. Akabane derived great pleasure from teasing and taunting those around him, and his favorite toys were Ginji Amano and Ban Midou.
Akabane played his games with his 'coworkers' like anyone else might play a board game or a card game, and for many of the same reasons, as well.
It was just like Scrabble, really, only sicker.
