With Sei off on an expedition with Al, Yuri takes a shine to Aira. Sei confirms that the best way of summoning her saintly power is to think of Al, the man she loves. The thing is, she’s in no particular hurry to confess to him or start any kind of official relationship, despite the fact she’s already saved the guy’s life and they have superb chemistry. Meanwhile, the hulking Leonhart (no relation to Annie) thinks he might have a chance at Sei, but he’d only be setting himself up for Leonhartbreak—if Al doesn’t kill him first!
With the newfound realization of her feelings for Al, Sei has taken to blushing so much he asks if she’s ill…thought that might be less him being dense and more being courteous or playful. He’s not one to talk about blushing around someone, as he does it a lot around Sei. But besides the insertion of Leonhart, who is shaping up to be more of a big (or big little) brother to Sei than the vertex of a love triangle, there’s not much movement in the Sei x Al romance, which at least for Sei is the way she wants it, at least for now.
When the expeditionary group enters the deep forest, they come afoul of several nasty dark slimes, not at all like our pal Rimuru Tempest from TenSura. Sei is able to purify a bunch and shield herself, Al and others, but they’re soon pinned down by superior numbers. That’s when a column of flame heralds the arrival of Yuri…and Aira, who I’m glad to see in the field. It seems likely she and Sei will be fighting side by side next week, which is something I’ve been waiting for since they were first summoned!
