Kenta Kanzaki is a character from the anime and manga series The Dangers in My Heart, appearing as a classmate of the protagonists, Kyotaro Ichikawa and Anna Yamada. His first name was revealed in a question-and-answer section of a special manga volume. In terms of background, Kenta is a student who is also a member of the school's baseball club, where he serves as the catcher, a position that necessitates his simple, practical, shaved-head hairstyle.

Kenta's personality is defined by a striking honesty and a complete lack of pretense about his personal interests, particularly his tastes in girls. He is open and unashamed to express preferences that are far outside conventional beauty standards, often making blunt and peculiar comments. He has stated that he does not like girls who are "too beautiful," that he would be fine with a girlfriend who weighs over 100 kilograms, and that he prefers girls who might not smell clean. This forthrightness leads classmates, including Kyotaro who internally labels him a "creep" or "ugly girl lover," to consider him a unique or weird individual, but he is proud of his tastes and means no harm. Despite his perverted-sounding conversations with friends, he maintains polite public manners and is generally regarded as harmless by the female students, who feel secure that his romantic attention is exclusively focused elsewhere.

Kenta's main motivation within the story is simple and straightforward, revolving around his open admiration for his classmate, Honoka Hara. Her chubby, voluptuous physique aligns perfectly with his stated preferences, and he frequently compliments her and praises her openly. This crush is an open secret, leading to teasing from his friends, with Adachi calling him a pervert and Ota making suggestive jokes about Hara's body. His role in the story is primarily to provide comic relief and color to the class dynamics through his unfiltered commentary on relationships and physical preferences, while also serving as a foil to Kyotaro's more reserved and anxious approach to romance.

Regarding key relationships, Kenta is good friends with Adachi Shou and Chikara Ota, forming a trio that often engages in silly, intimate, and bizarre conversations about girls. His relationship with Honoka Hara is his most significant. What begins as mutual interest eventually develops into them dating outside of school, becoming an acknowledged couple. He demonstrates protectiveness and jealousy over her, such as reacting negatively when Kyotaro unintentionally called her cute. Kyotaro and Yamada indirectly facilitate their bonding on at least one occasion, highlighting Kenta's role in the larger group's interactions. Over the course of the story, Kenta shows development by transitioning from simply having a distant crush on Honoka to forming a concrete, mutually recognized romantic relationship with her. His excessive affection for her contrasts directly with Kyotaro's shyness, providing a different model of teenage romance within the narrative. As for notable abilities, Kenta possesses no supernatural or extraordinary skills. His most distinctive trait is his social ability to be brutally honest about his unconventional tastes without causing serious conflict, as well as his physical abilities as a baseball player, specifically as a catcher.
