Rimuru learns that Mjurran’s heart was stolen by Demon Lord Clayman, which ensured she’d have to obey him to live. As part of his ongoing quest to make things as “interesting” as possible, he sent her to spy on Tempest cast the anti-magic barrier within the capital to make things easier for the alliance of Falmuth and the Church.
Rimuru orders Mjurran detained until he has time to think of a punishment. He visits with and heals Hakurou and Gobta, whose spatial wounds couldn’t be closed by Shuna’s skills. Then he asks what I’ve been asking since her battle with Shougo: Where is Shion? Rather than say, Benimaru escorts Rimuru to the plaza to see for himself: Shion, along with Gobzo, are among the dead.
That’s right, Shion’s dead dead. He’s the first of his ragtag group of loyal companions to die, and she was killed protecting a child. Rimuru asks for time alone, re-creates Shizu’s mask and asks the Great Sage questions like “Why did this happen?”, “What should I have done?” “Was it a mistake to get involved with humans?”, and “Was I wrong?” The Sage has no answers.
Rimuru can’t understand why he can be so calm when such a torrent of emotions are surging and seething within him. He decides it’s because he too has become “a monster at heart.” As such, he’ll do what a monster like him can do and at least absorb Shion and the others as he did Shizu, with Gluttony.
But before he can, he’s interrupted by Eren and her party, who were the very first adventurers he encountered after being reincarnated as a slime. Eren comes bearing hope, if only the slightest sliver: it comes in the form of a fairy tale that has a basis in fact. She goes on to tell that tale, which we the audience recognize as the origin story of Demon Lord Milim Nava—lovingly rendered in a gorgeous watercolor/woodcut style.
Milim didn’t mean to become a Demon Lord, but when the king killed her only companion—a baby dragon her father created for her—she killed the king and wiped out his entire nation, killing tens of thousands. As a result, the baby dragon came back to life—but lost its soul when it died, thus becoming the became the Chaos Dragon, which Milim had to seal away.
While souls escape in all directions immediately after death, it dawns on Rimuru that the souls of Shion and the others cannot penetrate the barriers enveloping the capital. The souls are there, ready to be reunited with their resurrected bodies, thus preventing what befell Milim’s dragon friend. The Great Sage confirms there’s a roughly 3% chance of reviving everyone.
Naturally, Rimuru takes those odds, which while small are not zero. He thanks Eren, who turns out to be a damn princess, Eryune Grimwald! All this time she’s been disguised as an ordinary human so she could adventure freely; her party-mates are her royal guard. As the princess of the Sorcerous Dynasty Sarion, she pledges to help Rimuru with anything other help he might require.
First things first: Rimuru needs to get started on becoming a Demon Lord so he can revive everyone. First, he sets up his own barrier in case the other two go down. Then, he asks the Sage for the requisites of becoming a Demon Lord. Turns out he already acquired the Demon Lord “seed’ when he predated the Orc Disaster.
The seed requires nourishment to grow and sprout, in the form of a minimum of ten thousand human lives. Double that number from Falmuth/Church alliance just happen to be descending on the capital, so it looks like Rimuru is ready to go. But first, he returns to the reception hall, insisting that Mjurran “must die”, then killing her…though she doesn’t die!
The reason is simple: Rimuru never intended to kill her permanently, only for three seconds. That was enough time to destroy the artificial heart Clayman had placed within her—which doubled as a bug—and replace that with a new artificial heart. Mjurran is no longer tied down by Clayman, and free to be tied down (via marriage) by Youm.
She in turn immediately swears fealty to Rimuru as thanks for his mercy. Rimuru asks her and Youm for help with his crazy new plan. In a short while, he’ll wipe out the entire force of Falmuth and Church soldiers and mages, including Falmuth’s king. That means Falmuth will need a new king, and Rimuru picks Youm for the task. Once Rimuru is a Demon King, Shion and the others should resurrect, badda-bing badda-bang!
I’m all for this sequence of events unfolding. Sure, keeping someone like Shion dead would cement the consequences of Rimuru’s poor leadership. It would also crest palpable stakes, since if she could die, anyone could. On the other hand, Shion staying dead would be really lame. She got on my nerves at times with the drinking and violence, but like our blue friend I wasn’t ready to say goodbye. I want her back! Also, that Milim and Shion-heavy end sequence hit different this week.
