Alice Yabusame addresses everyone except his sister, Reko, using their full names and speaks in an oddly formal manner. He is quite aggressive in general, but with enough persuasion and trust, he can be kind and helpful. He can act a bit childish at times, and is a kidnapped participant of the death game. His mother tried to raise him as a girl during his childhood, because of this he slips into a feminine manner of speech when flustered/surprised. He was allegedly a perfect prisoner.
