So, I don't know if Kunigami was the only person in the wild card room or not, but if he was then that means he was basically in solitary confinement for about a month and a week. Spoilers, Kunigami went to the wild card room in chapter 94, when the 3 week tryouts for the blue lock eleven started. After the U-20 match there is a 2 week break. After that the Neo egoist league arc and then he is back in chapter 155. So in total that is 5 weeks in the wild card room if I did it right. And a month has 4 weeks. So Kunigami spent a little over a month in in solitary confinement, went through very VERY harsh training(Wild card tried to make a copy of Noel Noa), and if he did talk to anyone, it was probably a weird guy (Ego)through a screen. To add to that Shido said some rather impactful words that already messed with Kunigamis mental state. So yep that is all, and solitary confinement has not good effects, especially if it is for over a MONTH straight. Ok, goodbye! (Wait, is this not illegal? Could Ego get arrested? who knows) ( I checked its illegal, Egos going to jail)
