Sugata is the leader of the New World Discovery Club (新大陸発見部Shin Tairiku Hakkenbu?) at Tomoki's school. In the anime, Sugata usually opens the episodes with some philosophical narrations which reference historical explorers such as Magellan and Columbus. He is an eccentric scientist of sorts and visits Synapse by using Nymph's Dive Game portal. He lives in a tent by a river and is usually seen in his school uniform. Because of his camping lifestyle, he usually eats what he can forage and hunt in the wild, where he fishes and fights off bears.
Sugata appears to be old friends with Mikako Satsukitane, who refers to him as "Ei-kun", and whose servants call him master. He behaves in a generally deadpan manner unless it involves the "New World", or if it threatens to reveal his family background.
