Agalia Rept (アガリア・レプト, Agaria Reputo) is a defender for Shining Satans.
Agalia has tanned skin and is tall in height, with a muscular build. He has shoulder-length black hair, with three strands of hair being coloured olive-green. The ones on the sides resemble horns and the one in the middle falls over his face. He has golden eyes with black sclerae, a big nose, a broad chin and two stitches on his mouth.
Agalia played with his team against Inazuma Japan during the Football Frontier International. He didn't have much defending to do at first since Inazuma Japan was struggling with Shining Satans' plays and their captain, Endou Mamoru, wasn't able to stop Satan Gaul's Time Trance due to the timing of the technique. However, Inazuma Japan's players were able to figure out their opponents plays and quickly tied the score 4-4. At the end of the match, Agalia watched Inazuma Japan celebrating their victory after Haizaki Ryouhei and Kira Hiroto scored the winning goal with Penguin The God & Devil while some of his teammates helped Pazuzu Zaham to get up.
- His name is derived from Agaliarept, which is one of the two demons serving directly under Lucifer according to the 18th-century grimoire Grimorium Verum.
