Guest is a Giver (you can choose your special item) as well as Jabber and a bunch of others.

Jabber Wonger from Gachiakuta is a psychotic, thrill-seeking masochist who loves both inflicting and experiencing extreme pain.Unpredictable and Sadistic: Driven purely by his chaotic desires rather than a grand moral ideal, he switches between extreme emotions rapidly and revels in the distress of others.Disregard for the Weak: He completely dismisses people he views as weak or boring, while showing deep fondness, excitement, and respect for opponents who can actually put up a strong fight.The Thrill of Battle: He enters fights with a wide grin and lives for the chaos of combat, often testing dangerous poisons on himself or hurting his own body just to feel the rush and make his attacks unpredictable.
