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...
But we promised to discover 
an asteroid together!
!لكنّنا قطعنا وعدًا بأن نقوم باكتشاف كويكب معا
Wir haben uns doch versprochen,
gemeinsam einen Asteroiden zu entdecken!
Tu m’avais promis

Avevamo deciso di trovare un asteroide insieme!
Nós prometemos descobrir
um asteroide juntas!
Мы же дали друг дружке слово,
 что вместе откроем астероид!
