His resolve strengthens, realizing his existence is crucial to saving his loved ones and the world.

Eliot's Grand Experiment Unveiled

Cristoph Eliot explains the Loop and Kaoru's role in bridging the virtual and real worlds. Kaoru's immunity to the MHC virus makes him the perfect candidate for Eliot's experiment. Eliot's vision is to use Kaoru's genetic information to develop a cure for the virus, saving countless lives.

The Loop's Cancerous Cycle

The Loop turned cancerous due to a mysterious virus, mirroring the MHC virus. Kaoru learns that the Loop's history must be rewritten to prevent its fate from affecting reality. His mission is to break this cycle and restore balance, ensuring the Loop's downfall does not repeat in the real world.

Kaoru's Sacrificial Decision

Kaoru decides to undergo the NSCS procedure, digitizing his being to provide data for a cure. This selfless act means leaving behind his life, including his family and Reiko. Kaoru's sacrifice is driven by the hope that his actions will save his loved ones and countless others threatened by the virus.

Rebirth and Redemption

The NSCS procedure transports Kaoru's consciousness into the Loop, where he is reborn as Ryuji Takayama. This rebirth offers a chance for redemption, as Kaoru, now Ryuji, carries the knowledge to change the Loop's fate and prevent the spread of the virus to the real world.

A New Beginning in Loop

As Ryuji Takayama, Kaoru embarks on a mission to rewrite the Loop's history. He develops a vaccine for the ring virus, guided by hope for a brighter future for both worlds. Takayama's journey is one of resilience, ensuring life in both worlds can thrive once more.
