Steins;Gate: Open the Missing Link - Divide By Zero

When the mad scientist quits, reality itself begins to fracture.

Rintarou Okabe, exhausted by endless loops and the weight of his promises, finally snaps. He turns his back on Suzuha's desperate bid to avert a global catastrophe, convinced that rescuing Kurisu is a futile chase. Stripping away his eccentric “mad scientist” façade, he slips into the role of an ordinary university student, hoping anonymity will shield him from the crushing paradoxes of his own inventions. Mayuri, ever the heart of his world, notices the change and celebrates what she believes is his recovery, but Okabe’s eyes betray a lingering storm. Beneath the calm surface, a new divergence sprouts—a timeline where the very fabric of fate strains beyond what any one person can bear. As the world teeters on the brink of a new calamity, the special delves into the fragile line between surrender and resolve, asking whether abandoning the fight truly frees a soul or merely delays the inevitable.

This special depicts the alternate timeline where Okabe gives up on saving Kurisu, focusing on his resulting mental health collapse and abandonment of his eccentric persona. It's emotionally intense and psychologically heavy, serving as a bridge to the darker Steins;Gate 0 storyline.
