College student Iwatani Naofumi is reading a book titled "The Records of the Four Cardinal Weapons" in the library when he is suddenly summoned to another world and told he has to save the world as the Shield Hero, one of the Four Cardinal Heroes. And one morning, he finds all his money and equipment gone.
Scum or not, you're still a hero, one of 
the only beings who can fight the Waves.
سواء أكنتَ حثالة أم لا، تبقى بطلاً، وأحد الكائنات
الوحيدة القادرة على مقاتلةِ الموجات
Wohl oder übel bist nur du als einer
der Helden in der Lage, ihr entgegenzutreten.
Pese a estar podrido,
eres uno de los héroes.
Pese a estar podrido,
eres uno de los héroes.
Tu es une pourriture, mais tu restes
capable de contrer les calamités.
Feccia o meno, resti pur sempre un eroe,
le uniche persone in grado di affrontarle.
Canalha ou não, você é um dos heróis
que conseguirá lidar com as ondas.
Пусть и выродок, но ты Герой —
тот, кому по силам одолеть Волну.
