Wasps are Diurnal - S1.E9

On his way back from a trip to Honchou, Kazuma finds Hina at the park alone and hungry. Buying the desolate girl food and drink, he sits with her as she describes a recent fight with her father that drove her to run away, left with nowhere to go. Against his better judgment, he discreetly takes her in. Senka discovers the hidden arrangement but agrees to house Hina in exchange for housekeeping. News of this reaches her father, and following a failed attempt to extradite his daughter, Kazuma is challenged to tug-of-war in her name. The battle is fierce and close, but thanks to no small measure of luck, Kazuma wins.
