Ino decides to challenge herself by participating in the Earth Science Olympiad. It's her first real step forward as their club president.
As their second semester comes to an end, the club celebrates Christmas and New Year's together around a warm hot pot followed by star gazing.
Yet as they're excitedly looking up at the winter diamond, Ao suddenly begins to cry. She says everything's all right, but...
I just managed to remember a few 
because they're named after rocks.
.تمكّنت من تذكّر بعضها بما أنّها سميّت على حجارة
Ich konnte mir sie nur merken,
weil sie nach Steinen benannt sind.
Lo recordé porque se llama
como una piedra preciosa.
Me he acordado porque se llama
como una piedra preciosa.

Du coup, je les connais.
Alcuni nomi sono uguali a quelli delle pietre,
quindi li ho più o meno imparati.
Eu consegui me lembrar de algumas,
já que têm o mesmo nome que pedras.
Помню несколько, 
потому что они названы в честь камней.
