Smiley is of short stature and small build with fair skin and a light tan. He has voluminous curly peach-colored hair, a wide grin that masks his eyes, and silver double piercings on his left ear. Smiley is most often seen wearing the traditional Tokyo Manji Gang uniform but regularly matches outfits with his brother when he is not tending to gang duties. In the Valhalla timeline, Smiley has wavy shoulder-length hair and wears a predominantly white suit over a black dress shirt with a pair of dark loafers. Even as an adult, he retains his renowned grin.

Smiley is shown to be protective of his younger twin brother Souya Kawata and never wants him to cry. He enjoys a good fight and a strong opponent. He is extremely hard to read when fighting because of the constant grin on his face. Smiley is loyal to his friends but his strongest loyalty lands with his brother. He has a lot of respect for Manjiro Sano, as shown when he gets angry after thinking that Takemichi Hanagaki was disrespecting him.

• Authority

Smiley is the current Fourth Division Captain of Tokyo Manji Gang. Prior to his allegiance to Mikey, he was the leader of the Twin Devils Gang with Angry.

• Fighting Prowess

Smiley is recognized as one of Toman's most formidable fighters. During the battle between Toman and Tenjiku, Shion Madarame noted that Toman was easy to defeat due to the absence of the gang's strongest members, one of which was Smiley who was struck with a steel pipe and eventually hospitalized hours before the fight. Angry also continuously stated that Smiley would have beaten Ran and Rindo Haitani if only he was present and praised his brother for knowing what to do in his stead. Indeed, Smiley displays a skillful performance when fighting and always knows what to do when put in danger. He also has his limits when he fights but shows no mercy when he is challenged, as seen when he attacked and won against Kakucho, a Tenjiku Heavenly King, after Tenjiku's raid on the First Division.
