Kalicchi is married to Kaliyan according to Akilathirattu Ammanai, the holy book of the Ayyavazhi sect of Hinduism.
As soon as Kaliyan was born in an inverted form he was presented to Shiva.
Kaliyan replied, "Will that fellow, by wearing a snake on his neck, and ash on forehead and seated on a skin of elephant, be ready to give me what I need?"
(This is an allusion to when Shiva appeared in a form of endless lingam of light when there was a dispute between Mayon and Nathan as to who is the greatest and in order to subdue their pride.)
Shiva queried, "Shall I create a girl who was in equal strength with you?"
Then as per the request of Kaliyan, Shiva decided to create Kalicchi.
Shiva's vision falls keely on a left rib-bone of Kaliyan, and he in his mind thinks Manmadan.
