THIS was Maribel’s Master Plan? Are you Serious!

That Time I got Reincarnated as a Slime S4 Ep 9 Review

It’s storytime with Mr. Jay, no relation to the Joker. Once upon a time, there was a very happy girl with pink hair and godlike power. She spent her days playing with her adorable and easily marketable-as-a-plushie pet dragon. But then this Elven king wanted the girl’s power for himself, so he tried to assert his control by using magic to kill the dragon. But instead, the girl crashed out, became one of the first Demon Lords, killed the King, and leveled his kingdom. The survivors would build a new city that eventually became the ruins that Rimuru and the others are about to explore. Unfortunately for everyone, Maribel has gotten so desperate that she’s willing to do something just as stupid as the stupid king.

Let’s get one thing straight about this episode: it is just the setup to the climax of this first part of Slime Tensura’s fourth season. As such, anyone who came into this expecting some epic, Indiana Jones, Tomb Raider, Uncharted adventure is going to be sorely disappointed. In all honesty, though, those kinds of stories paint a pretty unrealistic picture of archaeology. There are moments when people make epic discoveries and fantastic treasures, but most of the time, archaeology is pretty uneventful. I should know; I took a class on archaeology 101 in college!

What I’m trying to say is that there is not a lot of action for most of this episode. Mostly, it involves exposition about how this city became the way it is as Kagali guides Rimuru’s group and the other explorers through the ruins. Though ruins would be a stretch, as the Dark Elves still live in the topmost sections. The rest is sealed behind magic barriers that only Clayman had been able to unlock. The plan was for the explorers they brought along to unlock it, but Rimuru does it in two seconds. Because of course he does. He’s lucky that those archaeologists are humble enough not to be offended by him making their jobs so easy.

The coolest part about this episode, though, is the mural that the group finds depicting the story I mentioned above. More importantly, though, is seeing how Millim reacts to it. It’s ancient history to everyone else, but to her, it’s looking back on a part of her life that she may not want to remember that well. And unfortunately for her, history is about to repeat itself thanks to Maribel, who’s so desperate to get rid of Rimuru that she’s willing to do something incredibly stupid. Something that not even Luffy would do!

Going back to the story about how Millim became a Demon Lord, much like how Rimuru used his evolution to revive Shion and the other citizens Falmuth killed, Millim used it to revive her pet dragon. The problem was that it was so hate-filled by its death that it went on its own rampage. Millim had no choice but to seal it away in a pocket dimension for all eternity. But now, Maribel has set it free to lure Millim away from Rimuru so she can control or kill him.

There are so many flaws to this plan that I dont even know where to start. Firstly, Maribel unleashed an angry dragon capable of leveling the world, endangering the lives of billions. Secondly, when Millim finds out who did this, she’s not going to be happy and want to know who did it. Lastly, does she really think that just luring Millim away will be enough to make Rimuru vulnerable? He’s still got Gobta and Shion.

To her credit, Maribel did think ahead by using the ruins for her trap. The security’s activation is enough to be a hassle for the group. But, again, this is Rimuru. So Maribel has no choice but to reveal herself.

I know I’ve heard speeches about how no one is created equal before, and they do have a point. There are always going to be people that are just better at some things than others and thus see the world differently. Though when the Founding Fathers of America wrote that, they meant that everyone has the same rights regardless of background. If everyone was truly the same and equal, the world would be pretty boring. That’s what Maribel doesn’t get, and that’s why she and Rimuru were always going to be at odds.

Next episode, the fight between Rimuru and Maribel finally begins! But let’s be real: we know Rimuru is gonna win. We just want to see how he wins.

I give “Investigating the Ruins” a 3/5
