1x21 - Sket Dance

Bossun bumps into Himeko outside on the weekend, and they happen to spot Switch and Yuuki meeting up nearby as well. Their curiosity piqued, they decide to trail the 'odd couple' into a shopping mall. Turns out Switch is helping Yuuki with a request- to choose and purchase a laptop, so she can create a website dedicated to her passion of all things occult. Hijinks ensue, with the embodiment of 'Otaku' and 'Occult' clashing their interests and respective positions(supernatural vs science) against each other all the way(in their usual fashion). Nonetheless, they seem to be getting along well(again, in their own way), and even Bossun and Himeko note how unusual it is for Switch to be going out of his way to help his 'archrival', Yuuki. Switch and Yuuki then bump into her old crush from middle school, Kobayashi, who was there with another girl. He talks down to Yuuki, which seems to rub Switch the wrong way.
