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.
I've been letting her cool off 
in the biology prep room.
.أنا أسمح لها بالاستمتاع ببرودة غرفة الأحياء التّطبيقيّة
Ich lasse sie sich nur im
Biologie-Vorbereitungsraum abkühlen.
Solo dejo que vaya
al salón de Biología.
Solo dejo que vaya
al aula de Biología.
Non, elle vient se rafraîchir
dans mon bureau.
La lascio solo
rinfrescarsi un po' in laboratorio.
Só tenho deixado que ela 
se ventile na sala de biologia.
Я просто даю ей охладиться
в лаборантской.
