With the island test over, Ayanokoji Kiyotaka and the others are enjoying their summer vacation on a luxury liner. Suddenly, they're interrupted by a new special test. Ayanokoji is called into the same room as Karuizawa Kei and others, where they learn that this test isn't strictly along class lines...
Staying in your shell all 
the time gets stuffy, right?
البقاء محبوسون طوال الوقت
سيشعركم بالاختناق
Ist doch auch unangenehm,
sich dauernd in seiner Schale zu verkriechen.
À trop vous enfermer sur vous-mêmes,
vous allez souffrir.
Non ha senso costringersi a fare i sostenuti.
Ficar muito fechado é
mais sofrido, eu diria.
Вам, небось, 
самим тяжело будет сидеть насупившись.
