Puniru disappears mid-training, and the show doesn't waste time pretending the mystery matters, what actually matters is watching Kotarou realize he's completely lost without her, even when she shows up again in increasingly ridiculous forms. The comedy landed harder this season because the jokes stop trying and just exist the way these two exist together, which is to say messily, stupidly, and with real weight underneath. This is a show about two people figuring out that love isn't about being cute or perfect or understanding what you're supposed to feel; it's about showing up, even when you arrive as a leaky package.
Kotarou's life takes an unexpected turn when Puniru, the adorable slime girl he's known for years, vanishes without warning during an intense cuteness training session. Left scrambling to understand her disappearance, he finds himself wrestling with emotions he'd rather keep buried. His carefully constructed routine crumbles as he realizes just how much her presence meant to him. Then something changes. A mysterious package arrives at his door, leaking and squishy, that turns out to be far more complicated than he bargained for. What unfolds is a second chance neither of them saw coming, wrapped in comedy, chaos, and the kind of awkward affection that comes from caring about someone who defies explanation. This season balances genuine emotional beats against ridiculous slime girl antics, creating a strange alchemy where heartfelt moments coexist with pure absurdity. Viewers who appreciate romance that doesn't take itself too seriously, mixed with fantasy nonsense that feels genuinely endearing, will find plenty to love here. Shape-shifting shenanigans and shape-shifting feelings collide.
