Tōru Kanzaki is a central member of the idol group X.I.P. He shares a longtime childhood friendship with fellow member Kento Fuwa. Before becoming an idol, he honed his vocal skills in his school choir, leading to his recognized singing talent within the group. Kanzaki is the shortest of all six idols across both X.I.P. and the rival group 3 Majesty.

His personality is marked by a candid, often apathetic demeanor. He frequently voices blunt opinions and habitually dismisses others casually, labeling them idiots. This straightforwardness defines his interactions.

In the "Tokimeki Restaurant: Miracle6" narrative, X.I.P., including Kanzaki, faces off against 3 Majesty. Both groups compete for the right to perform the legendary song "White and Black" at their 5th-anniversary event, a song historically associated with a disbandment curse. Overcoming the song's challenge required the unified effort of all six idols from both groups, shifting the focus towards collective achievement over rivalry.

The character originates from the "Tokimeki Restaurant" mobile game, where players managed a restaurant alongside interactions with him and other characters. The intellectual property continued through related media and events after the game ended service in 2018.
