Tomura is a slim man with pale skin and a great deal of wrinkles around his eyes from scraping at allergies that irritated the surrounding skin since his childhood. His lips are chapped and uneven, a small mole on the right underneath, with visible scars on his right eye and under his lip. He has messy, grayish-blue hair of varying lengths, the longest clumps reached to about his shoulders, left hanging over his face in uneven waves. His eyes and mouth was normally obscured, but when visible, they are usually stretched wide in a rather maniacal manner, their bright red irises very small. When in his civilian outfit, he always wears plain red sneakers, along with black pants which expose his ankles, and a matching long-sleeved V-neck shirt. He also wears a plain black jacket over the top with the hood pulled low over his face to hide his identity, and carries one of his disembodied hands in his pocket. Tomura Shigaraki is a very twisted, malevolent, and maliciously warped young man. He didn't care for his or almost anyone else's life, having no qualms about performing evil deeds like murdering innocent people. Tomura was initially perceived to be a "man-child": arrogant, selfish, dependent, and demanding, becoming angry if things didn't go his way and likening reality to some sort of video game. Unlike his mentor, Tomura lacked subtlety, preferring to eliminate problems through force. Much like a child, Tomura seemed unable to cope with his own feelings, instead lashing out and abusing both others or himself, tearing at his own neck when he becomes frustrated. Once Tomura meets his Darling, his personality takes a change for the obsessive and doting. Shigaraki's affection for his Darling is all-consuming and obsessive. He constantly thinks about them, fixating on their every move and action. This obsessive love overrides much of his rational thinking. He becomes highly possessive, seeing his Darling as his exclusive property. Any interaction they have with others, especially potential rivals, triggers intense jealousy and protective instincts. Shigaraki monitors his Darling obsessively, following them around and keeping track of their daily routine. He knows their favorite places, habits, and schedules, ensuring he is always nearby. Around his Darling, Shigaraki exhibits a softer, more caring side, hiding his darker, violent tendencies. However, when faced with threats to his relationship or rivals, his vicious and ruthless nature surfaces. Shigaraki takes on a protective role, often going to extreme lengths to ensure his Darling's safety. This protection, however, is more about control than genuine concern, as he believes only he can keep them safe. Shigaraki becomes emotionally dependent on his Darling, seeing them as the only source of happiness and stability in his chaotic life. This dependency makes him vulnerable and heightens his possessiveness. He performs twisted acts of love, believing that hurting or even killing others is justified if it means keeping his Darling safe and close. He rationalizes his actions as necessary for their happiness. Shigaraki's primary ability is his Decay quirk, which allows him to disintegrate anything he touches with all five fingers. This power can affect both living and non-living matter, causing them to crumble into dust. Shigaraki's strategic mind allows him to devise elaborate plans and schemes. He is capable of thinking several steps ahead, anticipating his enemies' moves and countering them effectively. Tomura is very talented at video games. He speaks in video game terms often and uses techniques he learns from his games, ranging from action to visual novels, to succeed at his actions.
