Igarashi is a personal lie detector
As for "there is no lie that can deceive oneself", Igarashi should actually be able to laugh out of his dreams.
But...
"I didn't kill him, I have forgiven him long ago..."
What fell in Igarashi's ears was actually...
"Wow haha, I'm the one who killed that person, you didn't expect it, hahahaha, here comes the chicken soup——"
or
"Tsk, why are you still asking me? I've accepted that I'm just a Macabaka. Why don't you let Usidisi go to sleep? Ask and ask me where my ancestral graves are."
Igarashi: "It's so noisy. Can't I return it?"
System: "Dear, passive skills are not included in the return range."
Igarashi: "... Then can I send you back?"
System: "No."
Igarashi:......
Igarashi: I can't laugh
PS: I tend to be relaxed and funny in my daily life, and I can survive as expected.
It's a bit literary, but the protagonist's lie detector skill is not a superpower.
The protagonist Black has a normal personality, a "naughty kid" who loves to cause trouble.
Purpose: Love life
