This is a just-under-one-second clip of Korekiyo Shinguji giving his dry, breathy 'kh kh kh' chuckle, three short huffs with no words attached. It feels sly, unsettling and faintly amused, like a quiet laugh from someone who knows more than they are saying. The laugh belongs to the anthropologist from Danganronpa V3: Killing Harmony.
