Devil Survivor 2
Dera Daka is, in fact, Airi Ban's father, and superior of Ronaldo Kuriki. He used to be a detective who was investigating JP's in secret. To prevent himself from being found out, he faked his death so he can continue his investigations safely. He also left a memo book behind for Airi, which the protagonist can acquire. If said memo book is brought to Ronaldo, it is deciphered, revealing the presence of a secret within the JP's database. The protagonist can pursue this lead to find logs from when Fumi was hacking JP's while under Botis' control. While the data is corrupt, part of it is deciphered, partially revealing Yamato's involvement with Polaris.

6th Day Friday's Partings
If the protagonist has followed Dera Daka's events up to this point, he meets with Dera Daka on Friday evening to find that Dera Daka has attempted to use Nicaea. The demon he summoned is Jikokuten, but Dera Daka is unable to keep up with the demons' might to seal the contract and is killed. After the protagonist finishes off the demons, Dera Daka asks for the protagonist to keep their meetings and his real death a secret, since to Airi, he is already dead.

Jikokuten is unlocked for fusion at the end of this event.
