Diligentia

"" —

Originally Riku Utamiya, Diligentia became a witch after Riku solved the Epitaph and became the successor to the Utamiya name. She was recognized as Solatium's successor, and was a very merciful being.

Unlike her predecessors, Diligentia still has a strong grasp of her former humanity, being genuinely remorseful for carrying on the murders of her family and even rejecting her own existence so that her game would be void and Piko can be free for another game.
