|Occupation:||Light Brigade member|

Kloak is a pale-skinned young man pitch-black hair and navy blue eyes. He typically wears a dark purple cowl, complete with long sleeves, which covers the rest of his outfit. Underneath the cowl is a purple shirt, black sweatpants, and black shoes.
Kloak is a reserved character with a tendency to speak in poetic dialogue. While he appears distant, he's actually quite friendly and able to make small talk.
Through Caius's power, Kloak can vanish instantly by turning into a shadow through his cowl.
Fitting his name and position in the Light Brigade, Kloak plays a Shadow Deck, which has a largely evasive strategy. His primary card is "", which he can eventually upgrade into "Caius the Mega Monarch".
