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 thinking about those things, 
but what's the real story?
،كنتُ أفكّر في هذه الأمور
لكن ما القصّة الحقيقيّة؟
Das wäre nun mein Schluss,
Pensaba en cosas como esa,
pero ¿qué hay de la realidad?
Pensaba en cosas como esa,
pero ¿qué hay de la realidad?
C’est mon hypothèse,
qu’en penses-tu ?
Questa è l'idea che mi sono fatto,
ma è davvero così?
Tenho pensando nessas coisas 
e tudo mais, mas será verdade?
Я вывел такую теорию, но правда ли это?
