After safely qualifying to become adventurers Taichi and Rin begin working out of the inn, Mithril, completing the easiest E-Rank quests. Then one day the guild makes its decision to directly entrust them with a difficult quest, holding high hopes for their abilities. The quest is one that D-Rank adventurers have already failed twice - the investigation of a smuggling operation in the slums.
There are two Xs on it, which means others 
have already failed it twice, right?
هناك إشارتا إكس عليه، ما يعني أنّه سبق
وفشلوا في إنجازه مرّتين، صحيح؟
Dass zwei Kreuze drauf sind, heißt, dass daran
schon zweimal andere gescheitert sind, oder?
Hay dos cruces. Significa
que ya fracasaron dos veces, ¿no?
Hay dos cruces. Significa
que ya se fracasó dos veces, ¿no?

Há dois x aqui, o que quer dizer
que duas pessoas já falharam, né?
Смотри, тут стоят два крестика.
То есть задание уже дважды провалили...
