Naotoshi Hayashida operates as a ruthless rival to Somuku Kanou, leveraging ownership of the Akushi casino to relentlessly undermine Kanou’s influence over Yukiya Ayase. He manipulates Ayase’s cousin, Tetsuo Ishii, into orchestrating a rigged Russian roulette game, staking his company’s closure and Kanou’s financial ruin on the deceitful gamble. Kanou subverts the scheme by loading a live bullet, reversing the trap and coercing Hayashida to release them after a tense hostage standoff.

Unwavering in his vendetta, Hayashida allies with corrupt politician Kudou to kidnap Ayase, drugging him to fabricate blackmail through a staged assault. Kanou counters by threatening Kudou’s daughter, dismantling the plot while exposing the politician’s crimes and securing Ayase’s safety. These ruthless strategies emphasize Hayashida’s readiness to exploit others, yet his plans consistently unravel against Kanou’s calculated ingenuity.

Defined by tenacity and morally dubious tactics, Hayashida’s relentless schemes position him as a recurring adversary, challenging Kanou and Ayase’s resolve while intensifying the narrative’s exploration of power clashes and ethical compromise.
