Makes sense. I also don't count Judgement of Corruption as her actual debut simply because it only flashed her name and the word "friend" without even getting a direct mention in the song nor an appearance.

Although, technically, you are right. Her first mention was in JoC. I just take the whole debut as "first appearance" as an actual visual appearance, such as Venomania's "debut" in Heartbeat Clocktower. Forgive the actor in me for being so trivial over this.
