Shige is a young lad of average height. He has unkempt, almost curly, jet black hair, and black eyes. He has a heart-shaped face, and his sideburns reach inches past his ears. Shige's left ring finger is adorned by a black ring with intricate patterns, and both his wrists are clad in dark bangles. He dons a three-fourth shirt with a black collar, black sleeves, and a printing on the chest area. In addition, Shige wears a pair of baggy black pants, and dark shoes.
Shige shares a close relationship with the residents of Garage Island. He cares deeply for his friends, to the point where he tears up over the fate that Gemma suffered. He goes out of his way to keep his friends from harm, as seen when he rushes to the Glory household, just to warn Haru of the havoc in town.
On the aftermath of Feber's assault on the Glory residences, Shige rushes to Haru and reports about a man rampaging around town. When Haru inquires about the people's safety, Shige breaks down in tears as he struggles to relate what had happened to Gemma. Hearing this, Haru leaves and calls for Shige to watch over his sister.
