Sherlock Shellingford is a young detective and the leader of a detective team who wields a supernatural gift known as a "Toys": the power of telekinesis, allowing the manipulation and movement of objects with the mind.

A past incident where these abilities were lost forced a complete reevaluation of identity and purpose, shifting from a reliance on supernatural power to the cultivation of conventional deductive reasoning and detective skills.

The character exhibits a notorious and exaggerated passion for sweet treats, particularly parfaits and other desserts, a frequently observed trait.

After the loss of their Toys, a primary motivation became the dedicated pursuit of training and study to become a genuine detective through hard work and intellect rather than supernatural means. This path entails continuous learning, focusing on logic and observation to solve cases.

The personality is cheerful, energetic, and determined, marked by a strong sense of justice and a desire to help others, alongside a notable stubbornness and single-minded focus. Interactions with teammates form a core part of the character's experiences, defined by collaboration, shared hardship, and mutual support.

A specific rival exists, often distinguished by a contrasting color scheme and a more cynical worldview. Their relationship is complex, rooted in a shared history and a fundamental disagreement on methods and philosophy, yet underscored by a twisted respect.

The character's development centers on overcoming the trauma of losing what once defined them and building a new, stronger self-concept through earned skill, perseverance, and the value of friendship. This journey involves setbacks and doubt but demonstrates consistent resilience.
