The clash with the Standuser of the Death 13 unexpectedly had a strong impact on Kakyoin's psyche. During the day he always looks the same as always: calm and stoic, but at night he absolutely cannot close his eyes. Any attempt to sleep ends with either simple insomnia, or, even worse, a panic attack. Kakyoin manages to sleep peacefully only when fatigue takes over his body, and the brain itself turns off for several hours of carefree sleep.

You can no longer look at his suffering.
