One of the ten Artificial Intelligences (AI) known as "Sephirah." Birthday: March 24th. Height: 163cm. A woman with a brown bob cut wearing a red headband. Optimistic and a bit of a klutz. She always carries a notebook with her, which supposedly contains everything she needs to do. Lobotomy Corp, the setting of the game, is divided into ten departments. The story progresses and departments grow as tasks issued by each department are cleared. In-game, progressing through the tasks of the "Control Team" she oversees increases the player's capabilities, such as allowing the change of game speed or issuing assembly orders to the main room. She does not enter containment units.

The female Tiphereth has a strong-willed and harsh personality. She is biting toward the manager and often makes remarks telling them not to interfere with work.

He often ponders philosophical questions, giving the impression that he is spacing out. She does not enter containment units.
