A character in the otome game La Grande. He seems to know something about the mysterious deaths or deletions of the male leads caused by a strange error. He is a difficult person to read, often wearing a dubious smile. Originally a minor noble of a Marquis family in the world of La Grande, he will kill the user under certain circumstances.

The Saintess of the Holy See in the world of La Grande. Though she has the appearance of a young child due to halted aging, she has lived through several generations of noble families. She is the only character who exists exactly as the original game story intended. Normally, she should have died as a penalty for her long life after having her divine power stolen upon the appearance of the new Saintess (the female protagonist). However, for some reason, she is still alive even after you logged into the game. She greets you with a smile and speaks in a soft voice, but being left alone with her is not recommended. She will kill the user under certain circumstances.

A sort of guide character who is by the user's side the moment they wake up. The voice of the notification windows that pop up during emergencies in the game is also this character's voice. In the 'normal state of La Grande' before the errors took over, he was an immortal NPC-like character. However, as the game story became twisted due to errors, he changed. While it remains the same that only the user knows he is connected to the system, he can now be discovered by other characters if you aren't careful. If that happens, Sis is highly likely to be killed by the game characters. Warning: Naturally, if Sis—the game's guide and your exit button—dies, there are no retries or returns to the real world for you. It will be Game Over in both the game and reality (Deletion). He is hiding something from you.

A character in the otome game La Grande. In the world of La Grande, where male leads have suffered mysterious deaths or deletions due to a strange error, he is one of the individuals watching you. It is unclear whether his interest is favorable or hostile. He will kill the user under certain circumstances.

The daughter of the Duke of Udel, the family that produced the Saintess. She is clear about rewards and punishments—to a cruel degree. However, as a relative of the Imperial family and the lady of the house that produced the Saintess 'Latel', no one dares to question her cruelty. A beauty with golden hair and golden eyes, looking as if she were sculpted from gold. In the original work, she was killed by the love interests after bullying the female protagonist in one of the endings. Due to the error, all the male leads who were supposed to help you have disappeared. She will kill you depending on your favorability level.
