Among all the personas currently implemented in the game, Daku is a Loner. Meaning that he will run home and called the police when witnessing murder. However, he will not respond if a camera is pointed at him as the animations for that are not implemented.

- He was implemented as of the January 1st, 2016 Build. He was only created when the modeler,Druelbozo, discovered that there weren't enough Occult Club members for the game.
- His name is a play on the phrase "dark arts" translated into Japanese: daaku aatsu (ダーク・アーツ).
- Daku may or may not remain in the game for he is not a true character and just a test dummy for debugging. If he does remain, he may undergo a heavy change.
