Tamsy presents himself outwardly as a levelheaded, nonchalant, and reliable Cleaner, maintaining a calm and supportive facade. Beneath this gentle exterior, however, lies a deeply calculating, sadistic, and manipulative puppetmaster with dark intentions. He enjoys noodles and passionate people while harboring a disdain for those who exploit weaknesses. His inner self—often revealed when he lets his hair down—reflects the true, unmasked complexity of his deceptive character. Tamsy favors comfortable, loose-fitting clothing that matches his relaxed demeanor. His striking hairstyle features long sandy or platinum-blonde hair tied up in a voluminous, messy bun, complemented by a vibrant navy-blue underlayer that splits into two long tassels resting over his shoulders inside white holders. He has fair skin, long feminine eyelashes, navy-blue eyebrows, a silver lip piercing, and noticeable facial scars. When his powers are dormant, his pale eyes appear pupil-less and pale yellow, but when he activates his abilities, they glow in distinct layers of yellow and blue. His vital instrument, known as Tokushin, takes the form of a unique yarn swift. This tool allows him to create and manipulate versatile strings used for binding, combat, and psychological torment. Notably, his instrument lacks engraved name markings, quietly mirroring his secretive nature and hidden agenda.
