Shin decides it's time to raise his adventurer rank, but waiting for him at the guild is royal summons from Bayrelicht.
Refusing stuff like that without 
a good reason only causes more trouble.
إنّ رفض أمور كهذه بدون سبب وجيه
.لن يتسبّب إلاّ في المزيد من المشاكل
So etwas grundlos abzulehnen,
könnte zu unnötigen Problemen führen.
Refuser sans raison valable
Rifiutare questo tipo di cose senza
una buona ragione causerebbe ancora più problemi.
Recusar coisas assim, sem um bom
motivo, só causa mais problemas.
Отказывать без причин
 будет очень невежливо.
