|Persona|| Teacher's Pet (9/2/17)|
|Appears||Week 1 (Debug)|
Daku has neat dark blue hair and bangs that cover his forehead. He wears black-rimmed glasses with the right lens being completely opaque. He wears a black choker with a crescent moon on it. If the club disbands, he will not wear the choker anymore. The top half of his face is shadowed.
Among the personas currently implemented in the game, he is a Teacher's Pet. If he sees a corpse or witnesses a murder he will report to his teacher, unless another Teacher's Pet already has. He will give Yandere-chan a suspicious look before crossing his arms if she aims her phone at him. He cannot participate in physical fights against murderers.
If he sees the player murder anyone, he will believe that they are possessed by a demon, according to Oka Ruto. If left alive, he will refuse to talk to Yandere-chan every day, and will damage her reputation every subsequent day until he's killed.
At 7:05 AM, Daku enters the school grounds. He walks to his locker at 7:10 AM and changes from his outdoor shoes to his indoor shoes. At 7:15 AM, he walks to the Occult Club on the first floor.
At 8:00 AM, Daku walks into Classroom 1-1 and sits at his desk. He starts his morning classes at 8:30 AM, and leaves to go back to the Occult Club at 1:00 PM.
Daku walks back to class again at 1:30 PM and participates in cleaning time between 3:30 PM and 4:00 PM. Afterwards, he heads to the Occult Club and stays there until the end of the day. If Yandere-chan joins in club activities, he will unsuccessfully try to summon a demon with the other members from 5:30 PM to 6:00 PM.
If the Occult Club is inactive, he will socialize with the other former members outside of the club during periods when he would normally attend it (7:15 AM, 1:00 PM, and 3:30 PM).
- He was implemented as of the January 1st, 2016 Build. He was only created when the modeler, Druelbozo, found out that there weren't enough Occult members for the game.
- His name is a play on the phrase "dark arts" transcripted into Japanese: daaku aatsu (ダーク アーツ).
- As stated in his student info, one of the lenses of his glasses is completely opaque. No student has ever seen his right eye. Some students suspect that he only has one eye because they have never seen it before, and prefers to wear an opaque lens over that eye than an eyepatch.
- Druelbozo states that Daku's appearance is a reference to Yu Narukami from Persona 4.
