I REPEAT there is no right answer to this, this is what you think which character would lie to the police of a crime they for real commit.

Senku cause he smart af

I'm betting it's hanako he would lied to the cop clean because of that cute face he has. Which the cop would let him go freely.

Hak... if it's for Yona.

I'm going with hanoko because hes the only one I don't know. The others just seem a bit to straight forward/ honest or just terrible at lying. Like take darkness she would just say what she did and then ask for punishment. Or senku who would say exactly what he did and even give the full explanation to the point where the cops don't even know what to do anymore

Wow dude so your smart-smart I never thought about that.

Senku or Darkness

Hanako lies all the time, so an obvious choice.

I would say senku

This question is oddly specific.
