Mantis is a cerberus-orthurian hydra hybrid and one of the future eight offspring of Koji and Kaya.


Mantis often overestimates himself and his capabilities. But out of all his siblings, he is easily the most skilled. He is very serious and seems to have no detectable sense of humor. He is commonly described by others as being "tightly wound."




Mantis was born at Ueno Castle and is one of the eight eggs laid by Kaya with her mate Koji. He is a hybrid between cerberus hydras and orthurian hydras. Mantis is a dark pale green color with three heads and two tails.


  • Mantis is named after the shade of green of the same name.
