Sonosuke is stated to be a "silent type" who avoids talking to others, the only exception being his romantic partner, Ruruka. Sonosuke is incredibly loyal and protective of her, drawing a weapon on anyone who gets close to her. He loves Ruruka's candy and she seems to feed him as a reward, him often resting his head on her lap as he eats and calling the sweets "dewicious". Once Sonosuke's trust is broken, it is very difficult to gain it back, as he believes "once a traitor, always a traitor".
As the Ultimate Blacksmith, Sonosuke is skilled at developing and using different weapons, and he stocks all kinds of hidden weapons inside his coat. His parents, who were also blacksmiths, taught him from a very young age. At the Academy, he opened his own shop to take requests from people to forge any weapons they requested. He created weapons for two purposes, practical and collection. He takes a special interest in weapons that would typically used by ninja. He is also shown to be able to create many kinds of traps, including explosives that can be triggered with a switch or pressure activated traps.
~!He is the sixth person to die during the Final Killing Game. While it first appears that he was stabbed with one of his own weapons, Kyoko Kirigiri later discovers and reveals that he actually died from NG code poisoning from his bracelet after he violated his code, "don't put food in your mouth". Ruruka was so afraid of a possible betrayal that, when they're alone, she pulls Sonosuke into a kiss and then puts a sweet in his mouth, "betraying him before he can betray her". Sonosuke tastes the sweet and his NG Code activates the poison. However, Sonosuke doesn't consider it a betrayal and says that he loves her, giving Ruruka one final kiss right before he dies.!~
