Shiggy

Shiggy is an orphan from the Belchero Orphanage in the town at the edge of the Abyss, Orth. Like all the children of the orphanage, he's studied to become a delver since a young age and attained the rank of Red Whistle after his first descent.

Appearance
He has short dark hair and bright-red eyes, wears rounded glasses, and bears a red whistle around his neck. He is often seen in his plain white sailor collar shirt and khaki green or black pants and track shoes.

Personality
He has a great inquisitiveness, especially when it comes to the maps of the Abyss. He's helpful and kind and gives Riko plenty of advice. For someone so little, he has a lot of wisdom.

Intelligence
From what we've seen of him, Shiggy is the brains of the team at Belchero; whether he's making plans on how to sneak Reg into the orphanage or briefing Riko on the dangers of the Abyss, Shiggy's intellect is an important asset to the others.

Delving
Shiggy can travel into the Abyss's first layer because of his rank as a Red Whistle, which means he is likely a skilled beginner delver.

Trivia
