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.

Mira, here's the key to the 
roof that you asked for.

Mira, du wolltest doch

Mira, voici la clé du toit
que tu m’as demandée.
Mira, tieni le chiavi del tetto che mi avevi chiesto.
Mira, aqui está a chave do
terraço, que você pediu.
Мира, вот ключ от крыши,
о котором ты просила.
