As summer comes to an end, Hase comes to visit. But Akine says that Yushi's training isn't hard enough, and asks the landlord to make... a waterfall?!
It's been so long since 
someone's taken me seriously.
مضى وقتٌ طويل مذ أخذني أحدهم على محمل الجد
Hacía mucho que no me tomaban en serio.
Hace mucho que no me toman en serio.
Há muito tempo não me levam a sério.
Давно мне не встречались люди 
с таким серьёзным подходом к делу.
