Abilities and Powers

Natural Abilities

• Spiritual Sensitivity: Tsukiko comes from a highly curated spiritually aware bloodline of the Himorogi clan and thus is sensitive to lingering emotions and spirits around herself - her abilities allow her to perceive recent to long dead spirits and 'feel' traces of powerful emotions. This is amplified in large cities, making it sometimes overwhelming for Tsukiko.
• Mental Fortitude: While not as physically strong as others, Tsukiko's mental strength is on another level. Her mind cannot be easily broken, thanks to the grueling training of her youth. 
• Spiritual Projection: Spiritual projection is a unique ability to their clan that only a few have the aptitude to master. Instead of fighting with a sword, Tsukiko can infiltrate onto another's mind. While useful, this leaves her unable to move and thus is very vulnerable to physical attack. The farther the target, the harder it is and more strain it puts on her body and soul. Direct physical contact is most effective, but highly risky to her soul being corrupted by her opponent. Tsukiko can also concentrate her spiritual energy into a highly effective "burst" that leaves everyone around her momentarily stunned or depending on the lethality, in a coma, but the result is a double edged sword and leaves her also temporarily paralyzed. 
• Akashic Record: Another perk of the Himorogi clan is the ability to access a place called the Akashic Record. All life leave traces of memory, emotion and other biological markers that are stored in a spiritual plane, separate from the physical world. All past, present and even future branches/memories/history are located there. However only those with deep spiritual connection can enter and navigate it. Even then it is highly dangerous and one can be easily lost, forever separated from their physical body. Tsukiko, Kazuki and Kaguya are the only known members of the clan who could enter and navigate. The Master has often asked for Tsukiko to locate and search through memories to find any sort of lead or upper hand against Muzan.
• Keen Intellect: Tsukiko often scouts ahead of her fellow demon slayers and pinpoint demons and their victim's location. During battle she is quick to determine a course of action and find the most efficient solution to kill a demon while figuring out the best location to do so. Outside of combat she can be seen teaching other demon slayers tactics against and basic techniques to protect their minds, her easygoing personality and simplistic teaching methods making her highly effective.
