Souma is really susceptible to cracking up, and even memories will put him into laughing fits. But being self-conscious about this, he always tries to hide it. When he does this again at a clothing store his friend works at, the friend asks him why he does that, especially when it's so easy to tell anyway. Later, Shun also repeats the same sentiment...
Pretty sure we have one.
أنا متأكّدٌ بأنّ لدينا واحد
Glaub, wir haben noch eine.
Ich hol sie schnell.
Creo que quedaban. Iré por una.
Por mientras, sigue mirando.
Creo que quedaban. Iré a por una.
Sigue mirando mientras.
Je crois en avoir.
Un instant, je vais te le chercher.
Dovremmo averla, vado a prenderla.
Acho que temos.
Вроде была. Сейчас принесу.
