That Time I Got Reincarnated Again as a Workaholic Slime

Rimuru's Funniest Alternate Universe Adventure

That Time I Got Reincarnated Again as a Workaholic Slime is a comedy-focused spin-off that reimagines the world of That Time I Got Reincarnated as a Slime in a completely different setting. Instead of ruling the Jura Tempest Federation in a fantasy world, Rimuru finds himself dealing with deadlines, paperwork, office politics, and the pressures of corporate life.

Unlike the main anime, this spin-off is a non-canon alternate universe story designed purely for entertainment. It takes familiar characters and places them in a modern workplace environment where meetings replace monster battles and office responsibilities replace nation-building.

The series embraces the absurdity of its premise, delivering a lighthearted parody that pokes fun at both workplace culture and the Tensura franchise itself.

Story Summary

In this alternate version of the Tensura universe, Rimuru is no longer building a nation filled with monsters and allies. Instead, he finds himself reincarnated into the world of office work, where endless paperwork, meetings, reports, and deadlines dominate everyday life.

Despite still retaining his familiar slime appearance, Rimuru must navigate the challenges of modern corporate culture. Whether dealing with demanding supervisors, workplace misunderstandings, or the constant pressure of productivity, he quickly discovers that office life can sometimes feel more dangerous than fighting Demon Lords.

The spin-off transforms many familiar characters into office workers, managers, and coworkers while adapting their personalities to fit the corporate setting. Relationships that originally developed through battles and adventures are reimagined through workplace interactions and comedic situations.

The result is a playful parody that uses the franchise's popular cast to explore themes of overwork, stress, and office culture through humor and exaggeration.
