After reading the introduction to the dressing mirror named "Voice of Forgetfulness," Angel vaguely feels something amiss.
"Make the user forget someone or something," this effect isn't particularly potent, as spell techniques can achieve it. For example, Angel uses the Power of Nightmare Illusion to infiltrate others' minds, achieving a similar effect.
To say even more, without using Extraordinary Power, a simple physical impact might cause a brain neural short-circuit, tossing the Memory Casket into the Abyss of Thoughts, ultimately resulting in amnesia.
Therefore, in Angel's view, this tool seems somewhat redundant. He doesn't understand why Culori recorded it specifically and even wrote annotations.
Could it be because Culori crafted this dressing mirror himself, which is why he recorded it specifically?
Angel's gaze stops on the second line "Hoopa Coefficient: 2." What exactly is this Hoopa Coefficient? He has never heard of it.
