It's a day of new beginnings at the College as Chise attends her first day of classes and meets some of her fellow students, and Elias adopts a mysterious guise for his first time teaching as a visiting instructor.
Observe everything. Note it down. 
Test it. Experience failure.
.راقبوا كلّ شيء. دوّنوا كلّ شيء
.اختبروا كلّ شيء. جرّبوا الفشل
Ihr werdet viele Dinge beobachten,
aufzeichnen, praktizieren,
Obsérvenlo todo, tomen nota,
Observadlo todo, tomad nota,
Il vous faut tout observer,
prendre des notes,
Dovrete osservare ogni cosa, 
registrare ogni fatto, provare, fallire
Observem tudo, anotem, testem, falhem.
Наблюдайте за всем. Записывайте.
Пробуйте. Ошибайтесь.
