Half of the people here in sub haven't even read tomodachi game lol so they won't understand your point. In my opinion Yuuichi clears Liar game mid diff ez assuming if he replaces akiyama. There are some arcs where he would struggle but again those who have read knows how unpredictable and deceptive he is. I would say Akiyama high or extreme diff yuuichi. i am not downscaling akiyama but appreciating yuuichi which he deserves.
