Tetsuo has offered to work with the girls to figure out how Hikari and Yuki, who don't handle heat or sunlight well, can spend summer in comfort. But the school's head teacher suggests that the demi girls' total reliance on Tetsuo might actually be hurting them in the long run. This weighs on Tetsuo's mind...
If we can't ask Sensei, we can ask Sakki!
!إن لم نستطع سؤال سينسي، فيمكننا سؤال ساكّي
Ich frag einfach Sakki,
wenn der Pauker auf stur stellt.
Si no podemos preguntarle,
vayamos a ver a Sakki.
Si no podemos preguntarle,
vayamos a ver a Sakki.
Si on ne peut pas lui en parler,
autant demander à Sakki !
Se al prof non possiamo chiedere,
possiamo rivolgerci a Sakki!
Se não dá para ver com ele,
 a gente vê com a Sakki!
Если у него спросить нельзя,
то спросим у Сакки!
