Shinichiro Sano

Shinichiro Sano is a supporting character in the Tokyo Revengers anime, primarily appearing through flashbacks and mentions rather than as an active present-day participant.

He is the older brother of Manjiro "Mikey" Sano and Emma Sano, as well as the adoptive older brother of Izana Kurokawa. Shinichiro was the founder and first-generation president of the Black Dragon gang, widely respected as a legendary delinquent figure in Tokyo's underworld despite not being strong in fights.

In terms of appearance (as shown in the anime's flashbacks), he has short, somewhat unkempt black hair, dull black eyes, a slim build, and stands around six feet tall with a heart-shaped face—bearing a strong resemblance to his younger brother Mikey.

His personality is kind-hearted, caring (especially toward his family and others), humble, and reliable. He's described as "weak to women, weak in fights, but reliable," yet he earned immense loyalty and respect from delinquents far stronger than him through his charisma, sense of justice, and ability to inspire and stand up for people. He ran a motorcycle shop (S.S. Motors) and taught his siblings about bikes, fashion, and delinquency.

Overall, Shinichiro serves as a major inspirational figure whose legacy heavily influences the story's events and characters, even though he's deceased in the main timeline.
