Origami finally stops being a plot device and becomes a person. Natsumi's arc hits different because the show actually commits to her damage instead of playing it for laughs. The action sequences carry real weight when they're not cutting corners, and the opening theme alone justifies hitting play. This season knows what it's building toward, even if the animation budget couldn't keep up with the ambition.

Shidou's romantic life just got even more complicated. Interdimensional beings called Spirits, who take the form of girls, keep appearing in his world, and their presence sets off devastating spatial quakes. The catch: he's the only person capable of stopping them. His method isn't combat or negotiation, it's romance. By making these otherworldly girls fall in love with him and sharing a kiss, he seals their destructive powers. The military's AST organization would rather destroy the Spirits outright, but Shidou refuses to let that happen. Six Spirits have already fallen for him, and they compete with one another for his affection, leaving him with endless headaches. Now new Spirits are appearing, bringing harder trials as he works for Ratatoskr to prevent further disasters and learns more about where the Spirits come from. Shidou juggles dates and relationships while keeping catastrophe at bay, in a mix of action, comedy and romance.
