Arc 2Aofuji and the Silver Dragon Society
Shinnosuke defeated Shinomiya Kai, then joined him and his friends in tracing a drug operation from the Silver Dragon Society to Takeshi Sagara’s gang. After the Green Leaf Alliance fought its way through Kaikyu, Mitsuhashi exposed his fake injury and knocked Sagara unconscious, while Shinnosuke insisted they make him confess.
- Shinnosuke entered a warehouse with Inoue Ryushi and the others, then rescued them from Scarface’s gang and urged them to report the drug shipment anonymously.
- Shinnosuke challenged Shinomiya Kai, defeated him in a savage fight, and completed his mission to dominate Aofuji High.
- Shinnosuke reunited with Nanako Ohara, welcomed her into the Nohara home, and later defeated Sugihara Kei in a bridge-side fight.
- Shinomiya Kai identified the Silver Dragon Society as the source of the drugs, so Shinnosuke took him and his friends to Chiba and forced Tsukikawa to hand over money.
- Shinnosuke bought a used motorcycle from Ryuji Danma, while Shinomiya Kai later reported that Tsukikawa had died in a fire at the Silver Dragon Society building.
- Shinnosuke and Shinomiya Kai followed Takeshi Sagara’s trail to Kaikyu, where they joined Mitsuhashi, Ito, and Imai to form the Green Leaf Alliance.
- Shinnosuke fought through Kaikyu’s 300 fighters and knocked many unconscious, but grew exhausted as the battle continued.
- Mitsuhashi pretended to be bloodied, sprang up to knock Takeshi Sagara unconscious, and demanded the extorted money back.
- Shinnosuke grabbed the unconscious Sagara and insisted that the group make him confess before leaving Kaikyu.
