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.
If you only see the human side, 
you won't understand their troubles.
،إن رأينا الجانب البشريّ فقط
.لن نفهم مشاكلهم
Aber begreift man sie nur als Menschen,
ignoriert man ihren Schmerz.
Si solo ves su lado humano,
no entenderás sus problemas.
Si solo ves el lado humano,
no entenderás sus problemas.
Si on ne voit que l’humain,
on ne comprend pas son mal-être.
Se vedi solo il loro lato umano,
non capirai mai cosa li preoccupa.
Se enxergar só o lado humano, 
não vai entender os seus problemas.
Глядя лишь на человеческую сторону,
не поймёшь причину его тревог.
