Apus represents a fabulous bird of paradise, as found in New Guinea, but it is a disappointing tribute to such an exotic animal. The name comes from the Greek apous, meaning “footless”, since the birds were originally known to westerners only from dead specimens from which the feet and wings had been removed.
Paradise is one of the students in Palaestra, and overcame the selection trials to enter the tournament known as Saint Fight, reaching the quarterfinals, where he faced Orion Eden. Paradise uses a technique against Eden, but Eden easily defeats him with a single blow with his Folgore Renaissance. Later, after the invasion of the Palaestra by Martians, Paradise is captured to absorb the Cosmos in the Babel Tower.
