Every week when I watch the OP and ED I wonder “When is Rimuru going to gain a human form?” Well, TenSura answers that question. There wasn’t much doubt that Shizu—or rather, Izawa Shizue—wasn’t going to get out of that bed in the hut. The curse was lifted, but her body, which had endured for decades, was at the end of its rope.
After giving Rimuru the full story of her eventful life after summoning, and learning his Japanese name, she asks him to eat her so she can rest in peace within him. Rimuru uses Predator as she requested, and has plans to meet and slug Leon Cromwell, even though that Demon Lord was the only reason Shizu lives as long as she did.
When Shizu’s former adventurers enter the hut, they’re shocked to see a kind of 3/4 scale Shizu with blue hair and yellow eyes: it’s Rimuru! Or rather, a new form Rimuru gained by absorbing Shizu, which he explains was her explicit wish.
They’re not mad, just sad they couldn’t say goodbye to Shizu. But after being supplied with some top-shelf gear from Kaijin and his friends (who are famous to the adventurers as masters of their craft) they say goodbye to Shizu through Rimuru’s human form, and then head home.
Having met and absorbed his “destined one”, Rimuru builds a simple grave for Izawa Shizue under a tree perched on a cliff with a view of the village, then prepares to gain more information on his new world before confronting Leon Cromwell.
Meanwhile, a pig-man is on his last legs in the desert, but is saved by an oddly well-dressed man named Gelmud who hides his face behind a Venetian mask. He names the pig-man and offers him food in exchange for his fealty. Gelmud has plans for his new “project” that relate to the Jura Forest, so no doubt they’ll be crossing paths with Rimuru and his crew.
