True to the series’ reputation, the animation quality remains exceptionally fluid.

Episode 3 also deepens the relationship between the siblings. Mihari is often framed as the "mad scientist," but here her role shifts to that of a protective caretaker.

This caretaking allows Mahiro to experience a childhood innocence he likely bypassed during his years as a NEET (Not in Education, Employment, or Training). Physicality and Humor
