Percival

is the son of Ironside and grandson of Balgis, and is the main protagonist of the sequel, Four Knights of the Apocalypse.

Appearance
Percival looks like a very young boy showing a small and lean figure, despite being in his late adolescence, with green hair and purple eyes. His outfit composes of tunic cloth and short. He later wears his grandfather's purple horned iron helmet and an orange cloak with a brooch shaped like a serpentine creature biting his own tail.

Abilities/Equipment
Despite his small size, he is shown to be incredibly strong, beyond that of almost any human adult. This is best shown when he takes out a monster wolf the size of a house with nothing more than a slap to the face.

He has also shown the apparent ability to aim at targets behind him, how he achieves this feat is not yet understood. But it seems that this happens even when he fires at a target right in front of him with his bow and arrow.

Balgis
Balgis is Percival's grandfather and was his only family. Percival greatly admired and loved him, as the two had a very good relationship and never showed any signs of anger or annoyance with him.
