### Summary
A devastating flashback reveals the tragic origin of Izana Kurokawa's rage, stemming from his profound obsession with his perceived brother, Shinichiro Sano. The discovery that he shares no blood relation with the Sano family shatters his world, leaving a void of loneliness that Tetta Kisaki expertly exploits. This deep-seated pain culminates in Izana's cruelest act: murdering Emma Sano to make Mikey feel the same soul-crushing loss. The current, brutal battle between them is thus exposed not as a simple gang war, but as the tragic fallout of one boy's corrupted and desperate search for family.
