As Sensei proceeds home from school, someone calls out for "Tall Guy". It turns out to be Rin who sits with Sana. After they discuss nicknames for a while, Sana reveals to Sensei that she is allowed to touch Rin's skulls. She also reveals her insecurity as she wonders if everyone in class will be as friendly as Rin. Meanwhile, Rin responds by calling her cute. However, before she could reveal more, she stops speaking. Sensei figures that she was about to insinuate her sexual preference, however ultimately calms the situation down by calling himself and Rin "bros" (or, if she has bestowed that title on him, "homies").
