While sleeping in Rimuru’s goblin village, Shizu dreams of her wretched past, from when she was summoned from WWII-era Japan, was merged with Ifrit, and then essentially became a living weapon for the Demon Lord, who with one gaze can command her to destroy anyone from an interloping giant chicken to her poor friend and their unauthorized furry friend.
Waking up from a dream like that, it’s no surprise Shizu tries to make haste in leaving the village and her new friends behind, before the time comes when she can’t control the destructive power flowing within her. Unfortunately, her goodbyes run a bit too long, and Ifrit awakens in all his terrible fiery glory…right next to Rimuru’s newly rebuilt village.
To their credit, the experienced three-person party of adventurers don’t run, but try to fight to get their friend Shizu back, but Rimuru can tell they’re hopelessly under-leveled against a boss like Ifrit. However, Eren’s ice attack proves useful when Rimuru makes her use it agains thim and he analyzes and perfects it into a more powerful attack, which takes out all of Ifrit’s minions.
Ifrit counters by cloning himself dozens of times and surrounding Rimuru. When Rimuru takes the bait and blasts the clones with ice, Ifrit reveals a magic circle just beneath the slime, and casts Flare, enveloping Rimmy in a column of flame visible for miles around. The thing is…Rimuru is immune to fire, which means Ifrit is absolutely no threat, at least to the slime.
With that, Rimuru casts Predator and swallows Ifrit up where he joins Veldora in the void of the slime’s vast internal storage facility. Glad Veldora isn’t alone in there anymore! I have to admit I’ve missed the big guy ever since Rimuru ate him. In Ifrit’s place lies an unconscious but intact Shizu. Did Rimuru inadvertently free her from the curse she’s carried for decades?
