Kusakabe Yuki overhears some girls saying mean things about her. Gossip is not an uncommon problem among high school girls, but Yuki is particularly worried that it's happening because she's a demi. Tetsuo is sympathetic to thr concern and makes up his mind that, as her teacher, he must protect her. Hikari, a fellow demi, feels the same way.

Creo que debí hablar antes con ella.
J’aurais dû

para conversar com ela antes.
Всё же стоило заговорить
с ней пораньше...
